Copyright © 2014 Kepware, Inc.

Build Issue/Enhancement/Fix
V5.16.728.0
(11/18/14)
Application Report
  • Modified the Application Report Utility to capture process dumps from Kepware processes only. The utility released in 5.16.722.0 captured all process dumps on the system, which resulted in larger report file results than necessary.
  • Resolved an issue where the utility released in 5.16.722.0 could not correctly detect installed products when both KEPServerEX V4 and V5 were installed on the same system.
Build Issue/Enhancement/Fix
V5.16.722.0
(10/21/14)
Install
  • The OPC Core Components are now installed when the OPC Quick Client is installed. This allows the OPC Quick Client to browse remote servers if that is the only component installed.
  • The install will now notify users when another application is using the Sentinel HASP hardware key. In order for the Hardware Key to be properly installed, it requires that all Sentinel HASP hardware keys be disabled while the install is running.
Application Report
  • The Application Report Utility now gathers more information to enable the Technical Support team to better assist users needing support.
    • The utility was enhanced to collect running and core dumps for the KEPServerEX application.
    • The utility now gathers more diagnostic information about the system, including networking, .NET versions, and information pertaining to product licensing and DCOM settings.
    • The utility now remembers the last archive location and allows users to cancel an archive generation in progress.
    • The output archive was compressed and reorganized. Users are provided greater flexibility to manage the diagnostic, EFM, and Historian-related content in the output.
Server Configuration
  • Enhanced the tag browser to support both filtering of system and internal tags as well as bulk addition of tags from the branch level.
  • Added a status bar that is displayed when tags are moved between devices and tag groups using drag and drop to avoid the appearance of an unresponsive configuration application.
  • Fixed an issue that occurred in multiple File Open dialogs where the directory being referenced became the Current Working Directory in Windows and inhibited the directory from being deleted after the operation.
  • Fixed an issue where overlapping edits were allowed while the progress gauge was being displayed for a previous edit. Now, only one edit is allowed at a time.
  • Changed the Event Log message that indicates when a device was placed in Simulation Mode to tell users to reference the help file to understand how two tags with the same address in a simulated device may be separate tags if the tag scan rate and data types are different. Although this behavior in Simulation Mode is pre-existing, it is unexpected by most users.
  • Fixed an issue where undoing the deletion of a device would not display the tags that existed at time of deletion.
  • Removed leading or trailing whitespace in group names imported through CSV.
  • Fixed an issue that allowed the copying and pasting of a device with an invalid configuration on the last property page. The last page is now verified, and invalid settings are no longer allowed.
Server Runtime
  • Added a _SecondsInError System Tag to the device that shows the number of seconds the device has been in error state (_Error tag equal to 1).
  • Fixed an issue where the configuration and runtime could lock-up when a device was repeatedly enabled and disabled.
Quick Client
  • Added the ability to optionally use the system’s DCOM Configuration settings.
  • Added an Expand All option to the OPC Quick Client item browser that expands all branches in the tree.

V5.15.588.0
(09/23/14)
General
  • Maintenance release to fix a DataLogger issue introduced in 5.15.585.0. Please see 'Other' tab for details.
  • Additional fixes that were available were included in the release. Please see 'Drivers' tab for details.
Build Issue/Enhancement/Fix
V5.15.585.0
(07/22/14)
Install
  • Added the Omron NJ Ethernet Driver to the install.
  • Corrected how KEPServerEX version V4 is handled by the install: it is no longer removed on an upgrade. It is recommended users remove V4 as part of the V5 install, or manually uninstall V4 after installing V5.
Server Configuration
  • Fixed an issue where the CSV Import dialog retained an open handle on the import directory (which prevented users from modifying/renaming the directory until the server configuration was closed).
  • Fixed an issue where grid control lists would not automatically adjust their width for drop-down controls that contained large string options. This was discovered in DataLogger but also affected other parts of the server UI.
Server Event Log
  • Improved memory and CPU usage when processing large amounts of channel/device diagnostics, OPC diagnostics, and server events.
  • Improved performance and error handling on occasions where the Event Log service and server Configuration were accidently set to use the same port. This could occur with KEPServerEX alone or when KEPServerEX was paired with an OEM on the same machine. Unique system ports are always recommended for each part of the application.
Quick Client
  • Changed the default name of the Quick Client connection to "Quick Client". This allows Kepware's support team to easily identify via OPC Diagnostics if a customer is troubleshooting with the Quick Client or another OPC DA client.
Build Issue/Enhancement/Fix
V5.14.493.0
(03/04/14)
General
  • Maintenance release to address various driver related issues. (Please see 'Drivers' tab for details.)
Build Issue/Enhancement/Fix
V5.14.491.0
(02/18/14)
Install
  • Removed the sample client code examples that were written using the legacy OPC Foundation OPC 2.0 Automation Wrapper.
  • Fixed an issue where network and removable drives were not being shown when launching the installer with the /p option. When using this option now, the removable and network drives are visible and the product can be installed on them.
Server Administration
  • Access to the ProgID Redirect tab located in the Settings dialog is now restricted to users with "Modify Server Settings" permission.
  • Fixed the unhandled exceptions that were thrown when the configuration closed, which could have resulted in a configuration crash.
  • Fixed a bug where the Undo action was not properly handled during a CSV import.
Server Event Log
  • Improved the performance of the Event Log service under high load situations, which can occur when copying all Event Log messages to a file or when logging many messages at once.
Server Runtime
  • Added a new Read Only Boolean System Tag named "_System._IsDemo." This tag is true if the demo timer is tripped and the product is in demo mode.
  • Fixed an aliasing issue where aliasing would not work for drivers that use symbolic addressing.
Build Issue/Enhancement/Fix
V5.13.191.0
(10/15/13)
Server Administration
  • Resolved an issue caused when the Admin failed to switch the Process Mode setting (located in the server Administration's Runtime Process tab) to Interactive after viewing the Security Policies tab. This could cause a crash following the switch after the Security Policies tab had been initialized. The crash was caused by a failure to properly refresh the policy tree after the project had been reset, which resulted in access to project data that no longer existed.
Server Runtime
  • Added support for the new device-level "_DemandPoll" System Tag as part of the new Device Demand Poll feature available in this release.
  • Fixed an issue where a server crash could occur if a client removed the server reference while there were still references to a group or groups in the project.
  • Modified the runtime to allow the server to function on offline systems that require cached or online Certificate Revocation List (CRL) validation.
Server Configuration
  • As part of the new Device Demand Poll feature available in this release, added the new "Do not scan, demand poll only" option to the Scan Mode setting (located in the Scan Mode tab in Device Properties).
  • Added new a display option to the OPC Diagnostics window. The "Always On Top" option (located in the View menu) forces the OPC Diagnostics window to remain on the top of all other application windows. To match the Channel Diagnostics default setting for similar functionality, deselect this option.
  • Added the following new error messages to better clarify configuration problems related to Connection Sharing:
    • "A connection share pairing on COM <COM ID> is not supported by both drivers"
    • "COM <COM ID> currently exists in a different Virtual Network"
Install
  • Added a new dialog to the install. The External Dependencies dialog follows the Select Features dialog and is an informational window that indicates that certain features are known to have external dependencies and may require additional action prior to Runtime use.
  • The server installation no longer provides a copy of TcAdsDll.dll or the Beckhoff TwinCAT Remote Manager Utility. Users must obtain the TwinCAT ADS Communication Library from Beckhoff in order to access the tools that are required to configure successful AMS Remote Connections.
  • Resolved an issue with Silent Install mode, where installation to a removable drive failed when using the Hard Drive Check Override.
Build Issue/Enhancement/Fix
V5.12.142.0
(08/05/13)
Server Runtime
  • Updated to the latest Third-Party license redistributables to resolve an issue introduced in KEPServerEX version 5.11. A small number of customers reported an issue where the Server Runtime crashes when attempting to load licensing components. This issue was experienced by KEPServerEX version 5.11 and 5.12 users, and is not specific to project configuration or operating system.
  • For a description of the DataLogger Plug-In issue that was also resolved in this release, refer to the tab labeled "Other".
Build Issue/Enhancement/Fix
V5.12.140.0
(06/18/13)
Server Administration
  • Made the following enhancements to the built-in User Manager:
    • Added support for user groups.
    • Added support for the import/export of user and user group information.
    • Added new client access permissions to allow or deny read, write, and browse access.
    • Added new Event Log messages to report the following changes to user information:
      • Added user
      • Added group
      • Changed password
      • Changed user name
      • Changed user group name
      • Changed user group permissions
      • Moved user from one user group to another
      • Disabled user or user group
      • Enabled user or user group
      • Imported users
  • Initial release of the new Security Policies Plug-In, which is used to selectively apply client access permissions to any and all parts of the project namespace. The user interface of the plug-in is accessed through the Security Policies tab located in the Server Administration Utility's Settings dialog. To learn more about applying security to your application, refer to Kepware's whitepaper Leveraging KEPServerEX and Kepware's New Security Policies Plug-In to Meet Your Security Requirements.
Server Runtime
  • Stopped the OPC UA server from returning invalid items in a browse request. It is now consistent with OPC DA item browsing behavior.
  • Removed mandatory dependency between the Runtime service and TAPI, if it is determined at the time of installation that the TAPI service has been disabled by the user. To disable TAPI after server installation, utilize the Runtime Process tab located in the Server Administration Utility's Settings dialog and change the Runtime Mode to Interactive and then back to Service. This will remove the dependency.
  • Added access control checks for client read, write, and browse actions in addition to when using dynamic addressing to add items to the server.
  • Changed a behavior where the server would switch to the Default Network Adapter if the selected adapter was disconnected or disabled. The server will now continue to use the selected IP. When the server is assigned a static IP, this new behavior allows it to recover if a network adapter is unplugged or disabled.
Server Configuration
  • This version of the server contains a change in behavior with respect to Static Tags and the creation of client item references. In previous versions, a client item reference created from a Static Tag functioned like an alias: a tag could be changed after the reference was created and the next client reference would contain those changes. Starting in this version of the server, a reference count will be applied to Static Tags for each client item reference that is created from it. Consequently, a Static Tag with at least one client item reference cannot be edited or deleted.
  • Note: This change affects CSV import, and will cause it to fail if the target object has a client reference. It also affects automatic tag generation for devices that are configured to "Delete on create." When an automatically generated tag is encountered that should be deleted but cannot be (due to a non-zero reference count), the device will behave as if the automatic tag generation setting was configured to "Overwrite as necessary."
  • Updated the Event Viewer to support filtering for the new "Security" event type.
  • Removed duplicate "Starting <driver name> device driver" messages from the Event Log. The duplicate message issue was introduced in the 5.11 release.
Install
  • Added the new Micro800 Ethernet and Serial drivers to the Allen-Bradley Suite section of the Communication Drivers feature tree. These drivers will also be pre-selected for the Manufacturing Suite.
  • Added the Security Policies selection to the Plug-Ins feature tree.
  • Added the new Default Application Settings dialog to the installation wizard. This new page follows feature selection and contains settings related to Dynamic Tags and OPC UA client connections. It is independent of the Security Policies Plug-In.

V5.11.263.0
(08/20/13)
Server Runtime
  • Updated to the latest Third-Party license redistributables to resolve an issue introduced in KEPServerEX version 5.11.250.0 A small number of customers reported an issue where the Server Runtime crashes when attempting to load licensing components. This issue is not specific to project configuration or operating system, and results in the repeated failure of the Runtime during attempts to start and load the project.
Build Issue/Enhancement/Fix
V5.11.262.0
(05/03/13)
General
  • Maintenance release to address various driver related issues. (Please see 'Drivers' tab for details.)
Build Issue/Enhancement/Fix
V5.11.250.0
(03/05/13)
General
  • Windows 8 and Server 2012 are now officially supported.
Server Runtime
  • Reduced unnecessary memory consumption by waiting to load Internal Tags on demand instead of loading them all at once on startup. The on demand portion is driven by Clients connecting to the server and requesting items. For certain applications this update could yield a 50% reduction in memory use by the runtime.
  • Updated the Runtime to require that the Windows TAPI service is a dependency when the Runtime is installed as a service. This change was made to resolve a problem where the Runtime could fail to load after PC reboot if the server project contained serial drivers. The issue was initially identified by internal testing and was seen on Windows 7 operating systems and above.
Server Configuration
  • Resolved an issue where pressing the Tab key when focus is in the Channel/Device pane and there are no Channels defined caused the Configuration to crash.
  • Fixed a failure to show _Statistics at the device and channel level when working in the alias name dialog and the tag browser.
Install
  • Added the IEC 61850 MMS Client driver to the Communication Drivers feature tree. Additionally this driver will be preselected when the Power Suite is selected earlier in the install.
  • Added the OPC XML-DA Client driver to the Communication Drivers feature tree. This driver has been added to the OPC Connectivity Suite. The OPC XML-DA Client driver can be installed and activated for unlimited use with an existing OPC Connectivity Suite (OPC DA and OPC UA Client Drivers) license. Simply re-process the existing activation ID through the license utility and online license portal.
  • Added the EFM Simulator driver as a feature selection of the EFM Exporter plug-in. The EFM Simulator is a free component for users of the EFM Exporter. No license is required for the simulator.
  • Added the EFM Suite to the list of selections in the Vertical Suite Selection page of the install.
  • Removed VS2005 runtime redistributable from the payload of the install as it is no longer used.
  • Updated the example for the Custom Interface Driver (CID) to remove bad characters from strings and string arrays.
Build Issue/Enhancement/Fix
V5.10.205
(11/13/12)
Server Runtime
  • Added the new channel-level System Tags "_SharedConnection" and "_CommunicationSerialization._TransactionsPerCycle". Eliminated Property Tags from System Tags for consistency with 4.x. This also reduces memory consumption when a client browses a server address space that contains a large number of devices.
  • Prevented the server from loading drivers and plug-ins that fail digital signature verification.
  • Fixed an issue where the Key Service failed to start, resulting in an "Invalid or missing user information" message.
Server Configuration
  • Updated the user interface to support Connection Sharing.
    • Added a new view to show the list of channels.
    • Added a user-selectable organizational view of the Project Tree (by driver or connection).
    • Added access to the Driver Summary information from the driver organizational view.
    • Added an item to the Driver Summary information that indicates whether the driver supports Connection Sharing.
    • Provided drag and drop configuration for Connection Sharing project setup.
  • Changed the Communication Diagnostics view's color scheme to a grey background for RX and to green text for TX. The text and background color of TX and RX events is always set, so coloring will be consistent even on systems that have custom window colorings defined.
Install
  • Added the Connection Sharing Plug-In. It is selected for installation by default.
  • Added the ABB Totalflow Driver. It can be selected for installation independently or as part of the Oil & Gas product bundle.
Build Issue/Enhancement/Fix
V5.9.170
(06/26/12)
General

Windows 2000 is no longer supported for server versions V5.9 and up.

Admin
  • Fixed an issue where the User Access Control was not applied consistently to all the functions that required it in the Server Administration User Interface.
  • Removed the "Modify Server Settings" privilege from the Default User's list of privileges in the User Manager. The setting never allowed the Default User the privilege even when it was enabled.
  • Fixed an issue where privileged changes made in the User Manager were not applied to the active Configuration session.
  • Fixed an issue where the Help button located on the User Manager page linked to the wrong help file topic.
  • Fixed an issue where the server's Administration icon in the notification area of the Windows Taskbar was disappearing on Windows 7 64 bit operating systems.
Runtime
  • Fixed an issue where Ethernet Encapsulation would not initialize properly when the user switched from an invalid COM port to Ethernet Encapsulation.
  • Added support for automatically persisting channel and device diagnostics data to disk.
  • Added support for automatically persisting OPC diagnostics data to disk. OPC Diagnostics capture must now be enabled through OPC DA Settings (located in the server by clicking File | Project Properties).
Config
  • Added tag description length validation on both Automatic Tag Generation and CSV Import.
  • Updated the OPC DA 2.0 Automation Wrapper examples in the install to run correctly on 64 bit operating systems. They will now run under WOW64.
  • Fixed an issue where uninstalling the Wonderware InTouch Client Driver would inadvertently unregister the shared components required by Rockwell Automation's FactoryTalk HMI for loading its projects.
Build Issue/Enhancement/Fix
V5.8.109.0
(02/21/12)
Admin
  • Moved the User Manager from a separate dialog that was launched from the Administration menu to a tab in the Settings dialog (which is located through the Administration menu by clicking Settings | User Manager).
  • Enhanced the User Manager by adding granularity to specify whether users can modify channels, devices, and tags. Added a built-in user profile called "Data Client" to control whether clients can access Dynamic (Native) Tags.
  • Removed the "Allow clients to write to system level tags" option from the Runtime Options tab in the Settings dialog. Added it to the permissions list of the Data Client profile in the User Manager tab in the Settings dialog.
  • Updated the Event Log tab in the Settings dialog to provide grid control for Event Log persistence enhancements.
  • Streamlined host resolution to eliminate the need for user configuration settings. These settings have been removed from the Server Administration UI. The updated implementation is quicker to react to changes in network address mapping but the change should be transparent to existing applications. The drivers that use host resolution are as follows: Bristol BSAP, ControlLogix Ethernet, DNP Ethernet, Modbus Ethernet, MT Connect, Ping, Siemens TCP/IP, SNMP and Weatherbug.
Runtime
  • Fixed an issue where a deadlock could occur in Communications Diagnostics when diagnostics were published from a driver at the same time that a project was automatically saving.
  • The Administrator user will now always assume write privileges when logging in from the Server Configuration. Any existing writers (users) will be demoted for as long as the Administrator session is active. Overlapping Administrator logins will always favor the most recent.
Config
  • Channel Diagnostics are now referred to as "Communications Diagnostics". As part of this change, Communications Diagnostics can now be displayed at the device level.
  • Fixed the font corruption occurring on some non-English OS configurations that was caused by the unexpected destruction of a needed resource. Applied dynamic font replacement to the Device View in order to correct the inconsistent appearance under these same conditions.
  • Fixed the following issues in the GUI:
    1. Fixed performance issues when processing Runtime updates after Automatic Tag Generation (ATG) completes and includes a large number of nested tag groups.
    2. Fixed an issue where display of the Alias Name dialog or Tag Browser window was slow.
    3. Fixed the slow processing of multi-tag deletion.
    4. Fixed the incorrect advancement of the progress gauge on the Status Bar.
    5. Fixed the missing view updates in listen-only clients when processing a Runtime update that signals the addition of multiple devices or individual tags.
    6. Fixed the Tag Browser window's position restoration logic so that it works properly in multi-monitor situations.
    7. Prevented the Multiple Tag Generator Tool from replacing the active selection out from under the tag dialog after tag generation. This was causing problems in situations where a tag was selected in the dialog before the Multiple Tag Generator Tool was invoked.
    8. Fixed a failure to undo a CSV import.
Event Log

Added new persistence settings to support extended data storage. These settings are configured from the Event Log tab in the Settings dialog.

Install

A user is now allowed to transfer licenses between Virtual Machines. Eliminated the Virtual Machine (VM) detection and User Agreement UI seen prior to 5.8 when installing on a VM.

Build Issue/Enhancement/Fix
V5.7.84.0
(10/24/11)
Runtime
- Fixed an issue where a deadlock could occur while a client is adding items and one or more components is utilizing Lite Licensing.
- Fixed an issue where items in an OPC group could fail to update after Advise and Unadvise calls occurred during a call to the client's data change handler.
- Upgraded OPC Core Components to version 3.00.105.1. This version resolves conflicts between x64 and x86 versions of OpcEnum.
- Added a new system tag called "_OpcClientNames" that lists the names of all OPC clients that connect to the server and register their name through the IOPCCommon::SetClientName method.
- Changed the OPC DA "Return Initial updates for items in a single callback" compliance setting to be disabled by default for new installations of the server. In case of slow communications (slow protocols), it is recommended that this server configuration setting be disabled to improve responsiveness. This setting can be located in the server configuration by clicking File | Project Properties | OPC DA Compliance.
Build Issue/Enhancement/Fix
V5.6.122.0
(07/25/11)
Admin
- Added a new ProgID Redirect feature that allows users to map another server's OPC registration to KEPServerEX. This feature may be accessed through the Administration menu by clicking Settings | ProgID Redirect.
Config
- Initial release of Media Level Redundancy (MLR), which increases reliability by providing two basic types of redundancy: communications path redundancy and device redundancy. MLR operating modes include "Switch On Failure," "Primary Only," and "Secondary Only."
- Replaced the tab view on the left pane with individual View Menu items for selecting the edit mode. Added a drop-down menu to the toolbar for quicker selection (and to provide visual feedback on which view is active).
- Removed the Diagnostics sub-menu from the View menu, and then moved items from the Diagnostics sub-menu to the View menu.
- Added a device detail view to the server's right pane. When a channel is selected, the right pane will now display a list of devices that are assigned to that channel.
- Provided the ability to enforce a scan rate floor or fixed scan rate when polling underlying data sources. This feature can override the rates requested by client applications.
- Added communication serialization to the Channel Wizard Summary dialog.
Event Log
- Improved the Event Log's performance by increasing the number of records sent per packet.
Install
- Added support for Hyper-V.
- Added an option for Bundle Selection. Users can pre-select drivers by market vertical (such as Building Automation) before reaching the installation's Features list. The default option is "None", which does not preselect drivers. This change is only visible in new installations, and will not be displayed to users that upgrade.
- Updated VB.NET OPC client sample applications to work in VS2005, 2008, and 2010.
- Added the "SupportAgreement.rtf" agreement and updated the "LicenseAgreement.rtf" (EULA).
Runtime
- Added a new OPC Diagnostic message to indicate that the client-supplied shutdown notification sink is being called. The new filter "ShutdownRequest" was added to the Filter dialog beneath "IConnectionPoint (Server)" to enable this event. It is displayed in the OPC Diagnostics View as "Calling registered shutdown sink". The detail shows the return value from the call as "Client returned = <HRESULT>."
- Altered the shutdown sequence to ensure that the OPC Diagnostics generated during Runtime shutdown will be delivered to the Configuration before it disconnects.
- Fixed a server initialization issue that could result in a non-responsive service on system startup (which may cause a lockup).
Build Issue/Enhancement/Fix
V5.5.98.0
(03/02/11)
Allen-Bradley ControlLogix Ethernet (5.5.98.0)
A problem has been corrected which could cause data requests to MicroLogix models to fail with CIP Error 0x08.
Build Issue/Enhancement/Fix
V5.5.94.0
(02/18/11)
Config
- OPC Diagnostics will no longer be stopped when a project is uploaded or downloaded between the server configuration and the server runtime.
- A new Multiple Tag Generation tool was added to help users add a large number of tags into the server database quickly. This feature can be accessed via the "Tag Properties" page.
Runtime
- Fixed an issue where a runtime failure could occur when an OPC DA client attempts to use the IOPCAsyncIO2 interface without first setting up a data callback.
- Modem functionality has been enhanced to support auto-dialing and improved phone number management.
- Fixed an issue where driver communications could be interrupted by virus scans or other processes that block access to the hard drive.
- Added text to the server's administration "Runtime Process" property page clarifying that DCOM settings do not persist when the Process Mode is changed from System Service mode to Interactive mode.
Build Issue/Enhancement/Fix
V5.4.135.0
(11/02/10)
Install
- Fixed an issue with the 5.4.131.0 installation package where it was always setting the Process Mode to "System Service". This would affect users who have the Process Mode set to "Interactive" prior to upgrading from 5.x versions prior to 5.4.131.0.
- Fixed an issue with the 5.4.131.0 installation package. Future upgrades for users who installed version 5.4.131.0 will remove the registry settings related to DCOM and cause issues with remote connectivity. It is recommended that these users upgrade to 5.4.135.0: although the issue will persist in this case, any upgrades following 5.4.135.0 will not cause these problems.
Build Issue/Enhancement/Fix
V5.4.131.0
(10/28/10)
Config
- Fixed an issue wherein menu text was missing in Channel Diagnostics if a modal window was also open.
- Previously, both Import and Export CSV did not suggest a file name when the device or group contained a space. This was fixed by adding logic to accepted spaces, as well as the "-", and by automatically filling the file name for alphanumerics, digits, and the following special characters: ^&'@{}[],$=!-#()%.+~_
- The last viewed tab in the Tools | Options dialog now persists independently of how the window is closed.
- The size of the driver information dialog was decreased and made resizable.
- Added a check to the Device Wizard ID pages to make sure a new device can be added.
- Fixed a crash issue when property pages are open and a new project is loaded by double-clicking on an .opf project file. Now, users cannot load a new project if a modal dialog is currently open.
- Increased the text limit of the Numeric ID edit box to 6 digits in order to support the largest octal value that fits in a word. The width of the edit box was also increased in order to fit the new digit limit.
- Fixed an issue wherein the Alias Import/Export file dialog did not remember the last used path.
- Added an option to the View menu to show/hide plug-in tabs.
Event Log
- Added message pump for Third-Party applications that call SendMessageTimeout ().
Runtime
- Modified the server to post a message whenever the Licensing Service is not detected.
- Fixed an issue with copying and pasting devices on a driver that does not allow duplicate Device IDs.
- Fixed an issue wherein project backup was being created whenever the startup project was used.
- Plug-In tags are now included in the project tag count.
- Fixed an issue wherein clients were unable to reconnect to the server via SuiteLink/FastDDE after the server was reinitialized.
- Added check to project loader. This suppresses a warning message from being posted for a missing Advanced Tag plug-in if advanced tags data was not loaded.
- Set the default DCOM access permissions to the same for both Service and Interactive Mode. Previously, it was Interactive User, Self, and SYSTEM for Service Mode only. Now, Built-in Users and SYSTEM is for both.
Build Issue/Enhancement/Fix
V5.3.118.0
(06/09/10)
Config
- Added "Advanced" channel property page and a property called "Communication Serialization: Virtual Network". The page will not be shown for drivers that do not support communication serialization.
- Added support for auto-generated aliases in the alias map export if "show auto-generated aliases" option is checked in alias map dialog.
- Added support for UTF-8 encoding of CSV import/export files for aliases and tags.
- Removed the 'Contents' and 'Search' menu options from the help menu and replaced them with 'Server Help'.
- Corrected instance where undo information was not saved when multiple tags are copied and pasted.
- Alias map menu option is now enabled without requiring a device or a channel to exist in the active project.
- Fixed failure to open a project file when double-clicked in Windows Explorer if an instance of the Server Configuration is already running.
- Fixed an issue where the incorrect channel wizard page was displayed when both Ethernet encapsulation and RTS Manual flow control was enabled.
- Added a horizontal scroll bar to the hint box for cases where the length of a hint exceeds the size of the hint box.
- Increased COM ports range from 1-100 to 1-256.
- Fixed issue where "Auto Create" button on the "Database Creation" tab would not work until the "Apply" button was pressed. Changes made on sibling pages are now applied when "Auto Create" button is pressed.
- The server's event log now supports Event Type (Error, Warning , Information) for the Save-As-Text-file output. Output file is now UTF-16 encoded.
- A warning message was added to the Alias Name dialog if the alias name matches any of the channel names in the project.
- Added check for wizard page mode before enabling back and next buttons. Without the check, the cancel button was the default button in property sheet mode.
- The configuration client now waits a maximum of 30 seconds for the runtime to initialize (this was originally set at 10 seconds). This extra time will help prevent connection timeouts from occurring when the runtime is either starting on a slow machine or loading a large project.
Runtime
- BCD tag values are now clamped to the max value for their data type.
- Added support for user-specified startup project from any location in the file system.
Build Issue/Enhancement/Fix
V5.2.133.0
(02/18/10)
Admin
- Added support for OPC UA Configuration management
- From the Settings|Configuration tab added ability to enable remote connections to support Exchange feature of UA Configuration Manager (secure by default).

- Added support for OPC UA Project Configuration
- Fixed failure to close the channel diagnostics window attached to a recently deleted channel.
- Fixed "Runtime Update Failed" messages following tag duplication, object paste.
- Fixed the print button in the event log print preview.
- Resolved issue where the DCOM setting 'Identity' for the Configuration Client was not retained when "The launching user" option was selected.
- Updated project handling logic for case where a Read/Write user was not given a warning to save a modified project offline before loading new project.
- Updated project handling logic to prevent an update to the Runtime when connecting the Configuration as a Read Only user.
- For issue introduced in the 5.1 release, fixed failure to launch the server runtime process from the Configuration client if the Runtime is configured for interactive use and UAC is enabled.
- Updated the Alias browse GUI to eliminate the dependence on the parent dialog's check box with corresponding help update to better describe the "Show systems tag group:" checkbox. - Added enable/disable checkbox for AE project settings.
Runtime
- New OPC UA server interface v1.01 supporting optimized binary TCP.
- Improved DDE server capability when running as a service, to prevent MS Excel DDE client stability issues. (Requires interact with desktop to be enabled.)
- Fixed failure to apply Alias scan rate override to items added via the FastDDE/SuiteLink native interface.
- Added the ability for a user to specify the 'default' project to use the next time the runtime is started. This change is primarily for OEMs who use an external configuration utility to deploy a default project for the Runtime. The Runtime will look for user-supplied project.xml or project.opf file in the same directory as the default.opf at server startup
- Resolved issue where no client update was being generated from the OPC layer upon item state transition from inactive to active.

KEPServerEX v4 Updates and Versions

Current Release KEPServerEX V4.500.465.0
Copyright © 2014 Kepware, Inc.

Upgrading KEPServerEX v4 to KEPServerEX v5

Build Issue/Enhancement/Fix
V4.500.465.0
(07/20/09)
Fixed:
1. Fixed memory leak that occurs when loading invalid XML files, whether manually through UI or through our IPersistFile interface.
2. Fixed issue where an invalid branch could be returned to a client application when using OPC_BROWSE_TO
V4.500.462.0
(02/11/09)
Fixed:
1. Fixed issue where doing cache reads on an item that is inactive or belongs to an inactive group and whose requested data type does not match the cached data type could result in a memory leak.
2. Fixed issue when resolving hostnames.
3. Fixed issue where the server would stop accepting new client connections under stress in a terminal service environment
4. Fixed channel diagnostic's buffer view so that it now respects the buffer size setting.
We now send an item update to clients when the OPC group active state transitions from inactive to active, regardless if the last item update sent to the client contained the same value and quality.
V4.300.449.0
(08/29/08)
Enhancements:
1. Added support for the Oracle Connectivity Suite plug-in.
2. Added support for Advanced Tags feature. This includes Average, Complex, Derived, Maximum, Minimum, and New Oracle Cumulative Tags..
3. Added tooltip tips to the tag view so that when hovering over a field which is not fully visible you can now see the full text in the field

Fixed:
1. Fixed issue where server Active Tag count could exceed the Total Tag count as viewed on the server Status Bar.
2. Fixed issue where server would return an OPC Error if a Cache Read was made on an Item which had not received an Initial Update. Server now returns an appropriate Bad quality result.
3. Fixed issue where server would return an OPC Error if a Value could not be converted (e.g., out of range) from its Canonical data type to the requested data type in addition to setting the quality of the data Bad. The correct behavior is to simply set the data to Bad quality.
4. Fixed issue where Ethernet Encapsulation mode could change from Unsolicited to Solicited when editing channel properties.
5. Fixed issue where we could not open a legacy KEPServer 3.0 project if an invalid flow control was set in the project file. We will now set the flow control to none and allow the project to load.
V4.280.435.0
(04/30/08)
Enhancements:
1. Added OPC item property which allows access to the item's (tag's) address.
2. Added support for 64 bit floating point data for the iFix/PDB interface.
3. Added support for 14AL and 14BN signal processing for the iFix/PDB interface.

Fixed:
1. Fixed issue where the server would no longer automatically shutdown if a clients loaded a new project with the IPersistFile interface.
2. Fixed issue where unconfigured plugins (e.g., DataLogger) would incorrectly persist data in XML format preventing the project to be reloaded.
3. Fixed device wizard issue for drivers with no custom device properties, where selecting "Back" from the Summary page, shows the "Finish" navigation button on the previous page.
4. Fixed a memory leak issue when CSV tag import fails because of an unrecoverable issue.
5. Fixed issue where CSV tag import error messages were not referencing the correct record that caused the failure.
6. Fixed issue with float and double array precision in iFix/PDB interface.
V4.270.416.0
(09/27/07)
Enhancements:
1. Added ability to load XML files using IPersistFile.
2. Added ability for users to negate scaled values for a tag.
3. Added ability for users to configure the CSV delimiter to be a comma (,) or semicolon (;) under Tools | Options | General.
4. Added OPC compliance option which allows the user to control whether or not the server should obey the Locale ID set by the client.
5. Added support for Date data type to String data type conversions through the FastDDE/SuiteLink interface.

Fixed:
1. Fixed potential security vulnerability in regards to how the server validates OPC handles passed in from client applications.
2. Fixed issue where "Protocol" value always loads up as "UDP" for a driver configured in unsolicited Ethernet encapsulation mode (only when loading XML project file).
3. When loading a project that contains a network adapter that is not available on the machine, we will fall back and select any available adapter that is assigned the same IP. If both fail, we will fall back to default as before.
4. Added event message (warning) when writing to an item that belongs to a device that is disabled. Previously, we would silently fail the write with no message.
5. Fixed anomaly that could occur when canceling the Save dialog that is displayed as a result of shutting down the application with a modified project.
6. Fixed proper initialization of the 'LastUpdateTime' that is returned to clients in an OPC GetStatus call. Clients based off the .NET sample code provided by the OPC-F could see an exception being thrown in the .NET code if no updates had occurred at the time of the GetStatus call.
7. Fixed anomaly that could occur if we are sampling item data (OPC DA 3.0) with buffering enabled and the quality of the data changes to bad quality.
V4.280.435.0
(04/30/08)
Enhancements:
1. Added OPC item property which allows access to the item's (tag's) address.
2. Added support for 64 bit floating point data for the iFix/PDB interface.

2. Fixed issue where unconfigured plugins (e.g., DataLogger) would incorrectly persist data in XML format preventing the project to be reloaded.
3. Fixed device wizard issue for drivers with no custom device properties, where selecting "Back" from the Summary page, shows the "Finish" navigation button on the previous page.
4. Fixed a memory leak issue when CSV tag import fails because of an unrecoverable issue.
5. Fixed issue where CSV tag import error messages were not referencing the correct record that caused the failure.
6. Fixed issue with float and double array precision in iFix/PDB interface.
V4.270.416.0
(09/27/07)
Enhancements:

7. Fixed anomaly that could occur if we are sampling item data (OPC DA 3.0) with buffering enabled and the quality of the data changes to bad quality.
V4.264.401
(06/06/07)
Enhancements:
1. Added DataLogger component to KEPServerEX.
V4.264.398
(06/01/07)
Enhancements:
1. Added ability to load/save project configurations in an XML format.
2. Added functionality to save channel diagnostics as text file.

Fixed:
1. Fixed issue where "Save As Text File" for event log was omitting lines present in the event log.
2. Fixed issue where the server rejected writes for out of range data for tags that we configured for scaling and were clamped. The server now clamps the value appropriately to the low/high clamped value.
3. Fixed issue where renaming a device and auto-generating an automated alias (alias map) resulting in a duplicate internal record would cause the save to fail resulting in a corrupted file.
V4.222.376 (01/26/07) Fixed:
1. Fixed issue where the client count, shown in the status bar, could be out of sync with the actually number of clients connected. You could see a client count of zero, while having active tags.
2. Fixed Wonderware interface issue where an initial update for string tags with bad quality could cause a server anomaly.
3. Fixed iFix/PDB interface issue where we would provide invalid timestamp values when server has not read initial values from hardware and device is autodemoted.
4. Fixed iFix/PDB interface issue where a value may never be displayed as bad if written to as the device goes into error state.
V4.210.367
(11/17/06)
Enhancements:
1. Added support for Boolean arrays using the iFix PDB interface.

Fixed:
1. Fixed issue that could result in a server anomaly following a request timeout in iFix PDB interface.
V4.201.359
(07/19/06)
Enhancements:
1. Added ability to set the location and name of the server's event log. This can be configured under Tools|Options|EventLog.

Fixed:
1. Fixed issue in the OPC layer where data changes would not be seen after a float or double value is set to NAN.
2. Fixed issue where the server would register the DX Link Option on any installation update (servermain.exe –register), regardless of whether or not the DX Link Option functionality was enabled or not.
3. Fixed anomaly that would occur if deleting a device that previously created multiple aliases with the same name.
4. Fixed issue in the OPC layer where we did not set the quality of an item to bad, when we fail to convert the data to the requested data type.
V4.200.353
(03/24/06)
Enhancements:
1. Allow users to copy the license number and computer ID within our license dialogs so they can easily be pasted into an e-mail and sent to us.
2. This feature will always perform a backup of an existing project file prior to overwriting the file. This option can be turned on through the Tools|Options|General menu item.
3. Added capability to process OPC qualities than "Good non-specific" and "Bad non-specific" to our NIO Interface. This was required for our Triconex driver.

Fixed:
1. Fixed DA 3.0 Browse compliance test issues related to returning a null pointer for a continuation point value rather than the appropriate empty string.
2. Fixed issue when exporting aliases with item references that contain commas. This field should have been double quoted so that we can successfully re-import the csv we create.
3. Fixed issue where we would continue to process outstanding write requests on devices that were disabled.
4. Fixed issue where the _Error tag for a device was not set if the COM port was not available or invalid on startup.
5. Fixed issue where the _Error tag for a device was not set if the modem was not available or invalid on startup.
V4.190.341
(11/23/05)
Enhancements:
1. Added new system tag "_NoError". This value will be set to TRUE when the device is not in an error state and FALSE when it is in an error state. This is the inverse of our _Error tag.
2. Added tooltip support for the device ID setting found on the device property page. If the device ID exceeds the length at which it can be fully displayed, hovering over the control will display the ID in a tooltip.

Fixed:
1. Fixed event view painting issue when sorting the event list by Date/Time when Autoscroll was not selected.
V4.180.338
(08/12/05)
Enhancements:
1. Added event log message when the enabled state is modified on a device. On startup, a message for each device that is disabled is logged to indicate the disabled state.
2. Added the following application system tags: Date_Month, Date_Day, Date_Year4, Date_Year2, Time_Hour, Time_Hour24, Time_Minute, Time_Second, Time_PM. These tags break up the components of the existing Date and Time system string tags, so that client applications are no longer required to parse the strings to obtain the individual elements.
3. Last file Open and Save As paths are now shared rather than being separate. This makes it easier for users to open up the last saved project if it resides in a location that is different from the last opened project location.
4. Added multi-line tool tip support for the event view. If the column that the mouse cursor is over contains text that can not be fully displayed in the current view, a tool tip with all the data will be shown.
5. Updated event log Copy/Paste contents to include the date and time with each TX/RX frame in the same format as the event log and OPC diagnostics. This will assist with cross-referencing diagnostic information.

Fixed:
1. Fixed event view painting issue when sorting the event list by Date/Time when Autoscroll was not selected.
2. Fixed DA 3.0 compliancy issue when running on systems with multiple processors or hyper-threading enabled. Cloning a group with a requested interface that is not supported by the group could cause the server to not perform device reads on any item that referenced the same address (qualified ID) as an item belonging to the cloned group. The result is that the server would always return failure for a device read request on these particular items for the lifetime of the client/server connection that performed the Clone Group request.
3. Fixed DA 3.0 compliancy issue when running the server on a machine with multiple processors or hyper-threading enabled. Due to the nature of the fix and how it would affect existing projects the user must enable this compliance fix under Tools | Options | OPC Compliance : "Return initial updates for items in a single callback". When selected (compliant behavior) we will return all outstanding initial item updates in a single callback. When deselected (default behavior) we will return initial updates as they are available which could result in multiple callbacks. Note: If the server was previously running with Full Compliancy selected, this will automatically be deselected so that the pre-existing behavior is maintained.
4. Fixed potential application deadlock when viewing Channel Diagnostics and either Resetting or Pausing the view.
V4.170.328
(05/19/05)
Enhancements:
1. Full OPC Data Access 3.0 Support. 100% Compliance Test Success and Tested at the 2005 North American Interoperability Workshop in Tampa (4/25-4/29).
2. Ability to access Tag Properties as OPC Data Access Items (e.g., Channel.Device.Tag._Description, Channel.Device.Tag._ClientAccess, etc…).
3. Opened up the Channel, Device, Tag Group, Tag (etc.) naming convention to allow for non-alphanumeric characters other than the underscore. The only limitations will be the period (a special delimiter used by the server) and using an underscore as the first character in a name (a special naming convention indicating that the object is an internal/system object).
4. Added support for drivers to include a device ID wizard.
5. Added the ability to save the event log contents to a text file.
6. Added the ability to select or clear all OPC diagnostics filters with the click of a button.
7. Added [Topic Name] to Wonderware specific add item failure event messages.
8. Added demo expiration time left to the application's title bar (if in demo mode).
9. Added support for the drivers to set the quality and/or timestamp corresponding to the value read from the device.

Fixed:
1. Fixed issue with synchronous device reads blocking for a lengthy amount of time if a device has data collection disabled.
2. Fixed issue with asynchronous device reads never returning an appropriate callback if a device has data collection disabled.
3. Fixed item browse issue with leaves (tags) with the same name as their parent branch (device or tag group).
4. Fixed default serial communications settings for a channel when modifying the selected driver for the channel. This only occurred in wizard mode and only if the serial communications page was activated and then the back button was pressed to modify the selected driver.
5. Fixed the appropriate clamping of the scan rate to 99999990 milliseconds upon importing a value larger than 99999990 via CSV import.
6. Fixed driver library initial update behavior for tags with slow update rates (e.g., If a tag was scanned at 10 seconds, it could take up to 20 seconds (always a factor of 2) to send the client the initial update).
7. Fixed driver library performance issue when placing a device in simulation mode with large tag counts.
4.160.317
(03/15/05)
- Incorporated driver update for Siemens TCP/IP Ethernet and new drivers.
4.160.316
(02/11/05)
- Added support for auto-demotion of a device for most drivers.
4.150.304
(09/09/04)
- Updated server to comply with the latest 2.05a compliance test.
- Fixed OPC diagnostics issue with not being able to open up user-saved .opcdiag files if Auto Save was not turned on. When Auto Save was not tuned on we did not allocate an appropriate resource to be able to open other diagnostic files.
4.142.297
(09/09/04)
- Added support for 14400 and 28800 baud rate selections.
- Modified server to return the timestamp @ which the data actually changed when sending client OnDataChange events, rather than the latest timestamp in cache. Due to internal threads being preempted it was possible to update the cache twice before sending an update to the client; the first where the data changes, the second containing the same value but an updated timestamp to indicate the freshness of the cache. This new behavior is on by default by turning off the returning of the latest cache timestamp through the following servermain.ini: "Use Latest Cache Timestamp For OnDataChange Events.
4.141.293
(7/22/04)
- Fixed general issues with scaling BCD and LBCD array types.
- Fixed scaling precision issues when dealing with raw BCD and LBCD data types.
4.130.287
(5/28/04)
- Rebuilt with latest OPC-F supplied proxy/stub includes.
- Added milli-second resolution to OPC diagnostic events.
- Added OPC DX functionality to KEPServerEX.
- Added acccess to the OPC DX Configuration utility from the KEPServerEX menu bar.
- NIOToolkitinterface.dll: Corrected "over range" alarm on startup issue for IDS version. (V1.27.24)
4.120.274
(4/7/04)
- Fixed alias map resizing re-paint issues for machines that have modifed their Windows settings to 'Show window contents while dragging' setting.
.273 - Fixed ability to apply string filter to the flat item browse that correlated to 'channel' portion of the fully qualified item id (e.g, Channel_1.Device_1.Tag_1 -> Ch* would not return the qualified item ID).
.271 - Added ability to resize the alias map.
- Added ability to import/export aliases from/to a CSV file.
- Modified alias system filter to filter all auto-generated aliases.
4.110.270
(3/22/04)
- Library fix for all drivers.
4.106.269
(3/11/04)
- Added OPC Diagnostics Tool.
- Fixed proper clean-up of tags when a client disconnects in an improper fashion.
4.105.260
(1/09/04)
- Intellution NIO - Added support for AR and DR registers.
4.103.252
(10/30/03)
- Fixed Dead band issue when applying to scaled values.
4.102.251
(9/25/03)
- Fixed Default project path on new installations.
- Fixed issue with setting the modify bit appropriately when modifying custom channel properties.
4.101.241
(8/7/03)
- Fixed minor cosmetics to the GUI.
4.100.239
(7/10/03)
- Added timestamp to diagnostics when copying to the clipboard.
4.90.237
(6/09/03)
- Fixed object pointer validation (OPC Layer) to check to see if we have access to the specified memory location, prior to checking the object signature.
.236 - (Bug Fix #275) Allow clients to utilize the IOPCShutdown and IOPCItemProperties interfaces even when "Enable DA 1.0 connections..." is the only selectable option.
.235 - We now ensure that the AppId\LocalService= is set if starting as a service. This is required for COM clients to be able to connect. This state can occur since our setup interrogates servermain.ini (left over from uninstall) and configures the server to run as a service.
.234 - Reworked dxserverinteface/server mechanism for setting DX items (exposed as DA items) values and write complete notifications, due to Windows CE linking limitations.
.233 - Fixed possible deadlock when shutting the server down when a client is still connected.
.232 - Modified driver versions dialog to include plug-in information.
- Removed DDE from "DDE Scan Rate" in tag dialog, alias map references since this applies to DDE/WWDDE/NIO and possibly other future client/server methodolgies.
.231 - Fixed possible deadlock that could occur if 1 client is browsing for tags and another is adding/validating/removing items.
.230 - (Bug Fix #275) Allow clients to utilize the IOPCShutdown and IOPCItemProperties interfaces even when "Enable DA 1.0 connections..." is the only selectable option.
- (Bug Fix #103) The OPC layer could potentially send 2 initial update for a non-changing value if the update comes in after we check for initial data updates and we are looking for changed data updates. If the data has been changed, the initial update flag should have been set to prevent an extra update.
- (Bug Fix #277) Modified "FileDescription" field embedded in servermain.exe resource image from "Kepware Enhanced OPC/DDE Server" to "servermain.exe". This is so that messages generated by the OS use a generic name for private labels (e.g., "Are you sure you want to delete the shortcut to servermain.exe?").
- (Bug Fix #209) Fixed inability to re-purchase a lite version license when there is only 1 driver installed that is purchasable.
.229 - We now pre-validate the item ID in QueryAvailableProperties, so that when clients call this on a path that is not an item (i.e., Channel_1.Device_1), an error message is not posted.
- Removed assertions that occur when a client adds an item that references a tag that is currently set to T_DEFAULT. This is OK for tags that have undefined values and is handled properly.
.228 - OPC: Fixed potential HEAP error that could occur when freeing an item that has outstanding asynchronous transactions.
4.84.227 - Fixed Wonderware update issue with Wonderware clients connected via SuiteLink remotely. KEPServerEX was presenting only newly changed data to the Wonderware toolkit interface taking the burden of change detection upon itself. Through the help of our partner in the Wonderware channel, Software Toolbox, we were able to determine that the toolkit prefers that we pass it all data updates regardless of change.
.226 - Fixed issue where Wonderware tags would not respect Alias override of the tags scan rate.
- Fixed issue with the Intellution interface for users that were running Intellution as a service on NT/2000/XP. This only effected users running in this mode of operation.
4.84.225 - Enhanced driver to server interface to allow CE version of the driver to operate and load in the same manner as the desktop versions. This change has no effect on the desktop operation of the driver but does require that the server and driver be updated for compatibility reasons.
4.84.223 - Fixed demo mode operation for projects that contain drivers that support an unsolicited mode of operation. These driver will now timeout in their demo mode in the same way other drivers operate.
- This release now support direct access to KEPServerEX for Intellution users. The Intellution native driver interface is now built into KEPServeEX, therefore the OPC Power tool from Intellution is no longer needed.
.222 - Reworked help system to default to .chm rather than our legacy .hlp files.
- Added support for private-labeled resource DLLs to override the application description and version information on the About box.
- Modified how we launch .chm help files so that the main server window can receive the focus while the help file is displayed.
- Modified "demo expiration" message for private-labels that perform custom licensing.
.221 - Fixed TAPI issue regarding clients attempting to open a line that has not been previously closed. The server will close the line and re-open on the clients behalf rather than failing.
- Fixed lockup that could occur when a client loads a project through the IPersistFile interface.
.220 - Fixed issue with rejecting all client connection request if an IPersistFile::Load operation failed.
.219 - The OPC layer no longer affects the quality of active items when the group update rate is modified. The result is that any reads from cache during the period of changing scan rates at the device layer will return the last known value, timestamp and now quality.
.218 - Fixed canonical data type return when the OPC layer coerces the data type on behalf of the driver. Previously the canonical type was returned as the type the driver returns to the OPC layer. This should actually have been the type the OPC layer returns to the client.
.217 - Fixed OPC compliance issues with OPC Data Access Compliance Tool 2.04 SR4.
.216 - Modified resource wording: "Intellution NIO" to "iFix PDB".
.215 - Fixed Asynchronous 1.0 Read/Refresh stream pre-allocation issue that can occur with string and/or array data updates. If a string update contained a value that was longer than the previous value and this is updated between the time the stream allocation occurred and the time we actually updated the stream an anomaly can occur and/or the client will receive incorrect data.
- New Automation wrapper fixes server browsing for servers that respond as OPC DA 2.0 only.
.214 - Added generic support for custom driver licensing.
- Added generic support for hooking into our event messaging system.
- Modified OPC logic for setting a group active/inactive to prevent updates to clients that are in progress while the group is changing its active state.
- Modified OPC DA 1.0 cache-refresh logic so that we cancel a refresh request if between the request for the refresh and the actual packaging of the response the group is set to inactive.
.212 - Fixed wonderware add topic/item issue when the topic includes more than a <channel>_<device>.
.211
.210
- Fixed failure to trap changes to the write optimization method if the controls are enabled and a client has connected before applying the changes.
- Fixed repaint issue when closing a channel or device property sheet. The repaint issue occurs since we activate each page on the sheet for validation before closing the window. During the loop where we activate each page, the sheet is disabled for drawing so we do not see an distorted paint update.
- Modified 'Reset' in diagnostics view to clear all counts as well as the displayed bytes.
- Added CAUTION statement to the initial transfer driver license page to alert the user to use the same version of the server for both source and target machines.
- Fixed HEAP exception on shutdown due to accessing our main window object after it had been destroyed.

ODBC Client Driver (5.16.722.0)
  • Increased the maximum number of channels from 100 to 256.
  • Updated the driver so that it will not force the access of tags added manually to be Read Only when the Set write access for imported database tags option is unchecked. This option only applies during automatic tag generation.
  • Updated automatic tag generation to force the internal tags that should be Read Only to be Read Only.
OMRON Host Link (5.16.722.0)
  • Fixed an issue where the driver was not working correctly when unexpected characters were received from a non-Omron device that supported the HostLink protocol.
OMRON NJ Ethernet (5.16.722.0)
  • Fixed issues with reading and writing UTF-8 characters that exceeded the tag-defined length limit in bytes. Truncating the strings resulted in the strings being invalid. Strings are now truncated appropriately.

  • Changed tag addressing to define polled versus unsolicited tags by the address. All tags with the generic address are now polled. Unsolicited or RCB tags now have a special : address syntax. This allows clients to know if a tag is polled or unsolicited by looking at the address. Previously, there was one generic address syntax and a setting to enable RCBs. For legacy projects, all tags will become polled tags until the address syntax is changed.
  • RCB are now enabled on first client reference to an unsolicited tag in the block, and disabled when the last client reference is removed.
  • Updated automatic tag generation from SCL files to support <RCB>:<Data> syntax and to flatten the generated tag hierarchy. There are no longer tag groups for every nested 61850 object.
  • Added a configurable Integrity Poll Rate (ms) parameter to Device Properties to report when the server loses connectivity to a device when using unsolicited tags.

SNMP (5.14.491.0)
  • Fixed an issue where tags would have bad quality if the data type length was in long form.
  • Added (EncExtAsc) as an encoding identifier (appended to the OID in the Address field) so extended ASCII characters will be human readable instead of represented in Hex.
Yokogawa Controller Serial (5.14.491.0)
  • Fixed an issue where a block tag was being incorrectly set in broadcasting mode.
Driver updates below coincide with Server Release V5.13.191.0 (10/15/13)

  • Added support for the new "Do not scan, demand poll only" device-level Scan Mode setting as part of the Device Demand Poll feature available in this release.
  • Resolved an issue where reading initially inactive subscriptions would fail on some devices. This issue could be seen with the Lufkin Modbus Serial Driver when a read was initiated on an inactive subscription and the block size was modified on-the-fly before the driver was able to update the tag with data from the device.
  • Resolved an issue introduced in server version 5.12 that prevented duplicate names from being made unique during Automatic Tag Generation (ATG). This could be seen when performing ATG with the Fisher ROC Plus Serial Driver, which resulted in fewer tags being generated than in previous versions of the driver.
ABB Totalflow (5.13.191.0)
  • Increased the maximum number of supported channels from 100 to 256.
Allen-Bradley ControlLogix Ethernet (5.13.191.0)
  • Fixed an issue introduced in server version 5.11 where in certain conditions, reads and writes would be performed in the reverse order in which they were submitted to the driver from a client application.
  • Corrected the message size estimation for Symbolic Writes, which was making it possible to underestimate and overflow a request packet.
Allen-Bradley ControlLogix Unsolicited Ethernet (5.13.191.0)
  • Enhanced the driver to support ODVA Conformance. New features include Connected Messaging, ODVA Member ID, and EDS file.
  • Improved error handling so that unsupported data types (such as BCD and LBCD) will result in an "Invalid data type" error message instead of an "Out-of-range" error message.
  • Corrected a problem in dimension detection for tag paths that contain 16 bit element offsets.
  • Corrected a defect in element count calculation that was exposed by the Allen-Bradley Micro800 Ethernet Driver. The element count is now correct if the element offsets indicate that less than the specified element count need to be returned.
  • Runtime tag values are no longer reset when a device's slot configuration is changed.
  • Removed support that allowed users to specify Port 0 (system determined) for the EIP server binding. Because the driver binds a listen socket to both UDP and TCP for conformance, these ports must be the same.
  • Removed the potential server hang that could occur if EIP messages were being processed while a channel's Network Interface or Port was changed.
  • Corrected int64<->Double conversion to match behavior in ControlLogix Ethernet Master Driver.
  • Removed support for the Media-Level Redundancy Plug-In because it was never intended.

  • Enhanced the Fisher ROC Serial Driver to support User-Defined Points. This includes support for Dynamic Tag Creation as well as Online and Offline Automatic Tag Generation.
  • Added support for the following point ranges:
    • Lower UDP range: Points 22 through 39 (excluding 24)
    • Upper UDP range: Points 178 through 189
  • Resolved an issue where, depending on the size and number of parameters in a block, the driver could request more parameters than will fit into a ROC serial response frame. An example of this is reading parameters 53 through 75 of point type 80 on a FloBoss Model 107 device, which would result in framing errors and bad quality for the entire block of parameters.
  • Increased the maximum number of supported channels to 1024.
  • Added support for FloBoss Model 107 specific parameters in point type 14. This support resolves an issue where adding or enabling parameter 37 of point type 14 would cause the entire set of point type 14 tags to go bad.
  • Added support for FloBoss Model 107 specific parameters in point type 57. This support resolves an issue where adding or enabling parameter 5 of point type 57 would cause the entire set of point type 57 tags to go bad.
Fisher ROC Plus Serial (5.13.191.0)
  • Enhanced the Fisher ROC Plus Serial Driver to support User-Defined Points. This includes support for Dynamic Tag creation as well as Online and Offline Automatic Tag Generation.

    • Lower UDP range: Points 60 through 78
    • Upper UDP range: Points 196 through 254
  • Increased the maximum number of supported channels to 1024.
  • Resolved an issue where an EFM history upload from a device with five or less points configured in a history segment would fail due to framing error.
  • Added support for point type 177, Wireless HART.
GE Ethernet (SRTP) (5.13.191.0)
  • Improved performance of the PACSystems model by requesting bytes instead of byte per bit when reading symbolic variables that are in discrete memory.
Lufkin Modbus (5.13.191.0)
  • Added the new "First word low in 32 bit data types" option (located in the Data Encoding tab of Device Properties). The default setting is the same as the legacy behavior, which is checked. Projects saved prior to this update will be loaded with the default setting.
Omron Hostlink (5.13.191.0)
  • Fixed an issue where the driver could process the response for a different memory type other than what was issued in the request.
ODBC Client (5.13.191.0)

The driver would post the "Unable to open recordset on device (Reason: Query timeout expired)" error message in the Event Log. This issue was due to an unnecessary query being used to count the number of items in the table.
OPC XML-DA Client (5.13.191.0)
  • Fixed an issue where one tag with a bad address would cause all tags to have bad quality with certain XML-DA servers.
  • Added support for HTTP Authentication.
  • Added the item path to the tag address. The new syntax is <ItemPath><Delimiter><ItemName>. Tag import will read the item path; if it's not empty, it will build the tag address as displayed above. Users can specify the item path in Static Tags (which are manually created) in the same way. For a list of allowed item path delimiters, refer to the "Channel Setup" topic located in the help file.
  • Added the channel and device names to the "The item path <Channel>.<Device>.<ItemPath> is no longer available in the server address space" error message.
  • Added the item path (if it is not empty) to the "The item name <channel Name>.<Device Name>.<Item Path><delimiter><Item Name> is no longer available in the server address space" error message.
OPC UA Client (5.13.191.0)
  • Resolved an issue where the driver failed to import tags if the data type returned by the target server was VT_EMPTY.
Opto 22 Ethernet (5.13.191.0)
  • Fixed an issue where the driver sent a NULL terminator for CONT string writes.
SquareD Serial (5.13.191.0)
  • Enhanced the driver to allow users to set the Block Size, which is the number of registers that will be read in a single request. The valid block sizes are 16, 32, 64, and 128. The default setting is 16.
  • Fixed an issue where the driver transmitted erroneous PAD characters (0xfe).
  • Fixed an issue where the driver replied with the incorrect acknowledgement control frame.
  • Fixed an issue where the driver sent the acknowledgement control frame as two separate transactions.
  • Fixed an issue where the driver failed to send an acknowledgement control frame when it received an inquiry from the device and it did not have a tag to process.

  • Resolved an issue where the driver would not send a start command before reissuing the last command (on a retry attempt) if the socket was closed.
  • Fixed an issue where the driver refreshed the TCP socket when the Connection Timeout setting was modified.
  • Fixed an issue where the driver closed the TCP socket on the "WSAEWOULDBLOCK" error code, which is a Windows socket error code.
User-Configurable (U-CON) (5.13.191.0)
  • Fixed an issue where deadlock could occur if multiple pieces of outgoing data were queued while the driver was still processing incoming data. This change affects the Transmit and Transmit Byte Commands.
  • Fixed an issue where data loss could occur if there was still data on the wire from a previous transmission when either a Transmit or Transmit Byte command was called.
  • Added logic to handle writing packets larger than 1024.
  • Added support for the CRC-8 Checksum, which is listed as "Custom #15 (8-bit)." The checksum's CRC polynomial is: x^7 + x^3 + 1.
Yokogawa DX Serial (5.13.191.0)
  • Resolved an issue where deadlock could occur after multiple user-driven Automatic Tag Generation attempts were triggered from the Server Configuration's Device Properties.
Yokogawa DXP Serial (5.13.191.0)
  • Resolved an issue where deadlock could occur after multiple user-driven Automatic Tag Generation attempts were triggered from the Server Configuration's Device Properties.
Driver updates below coincide with Server Release V5.12.140.0 (06/18/13)
All Drivers (5.12.140.0)
  • Resolved an issue related to write performance where certain drivers with the ability to perform multiple writes per transaction were incorrectly performing single writes after an initial multi-write transaction. This change affects the following Ethernet drivers: BACnet IP, Beckhoff TwinCAT, Allen-Bradley ControlLogix Ethernet, Custom Interface, GE Ethernet (SRTP), Siemens TCP/IP Ethernet, Simatic TI 505 Ethernet, SNMP, Triconex Ethernet, and WeatherBug.
  • Changed the behavior with regard to how specific NIC adapters are handled. Prior to the 5.12 release, the server switched to the "Default" Network Adapter if the specific NIC adapter was disconnected or disabled. After the 5.12 release, the server will continue to use the specific NIC adapter initially selected. This change affects all Ethernet drivers as well as all serial drivers that support Ethernet Encapsulation.
ABB Totalflow (5.12.140.0)
  • Updated the driver to convert flow times reported by Totalflow devices in integer seconds to floating-point minutes. This makes flow times exported by the EFM Exporter for Totalflow meters consistent with other meter types.
Allen-Bradley ControlLogix Ethernet (5.12.140.0)
  • Fixed a defect in which the "Synchronize with Controller after" settings were not being respected with regard to Online and Offline edits.
  • Changed a behavior where the driver will now retry tags instead of failing them upon detecting an Online or Offline edit (except for Downloads). It's likely that the next attempt will succeed. Also, Offline edits will take priority over Online edits if both occur before being detected by the driver.
  • Fixed an issue where the Protocol Mode drop-down selection arrow would not redraw correctly if the selection invoked a vertical scroll bar in the grid.
Allen-Bradley Micro800 Ethernet (5.12.140.0)
  • Initial release of this new Ethernet driver, which will be part of both the Allen-Bradley Suite and the Manufacturing Suite.
Allen-Bradley Micro800 Serial (5.12.140.0)
  • Initial release of this new serial driver, which will be part of both the Allen-Bradley Suite and the Manufacturing Suite
DNP Master Ethernet (5.12.140.0)
  • Addressed a security vulnerability that could allow a master station to be sent into an infinite loop by sending a specially crafted TCP packet or through serial communications. A successful attack exploiting this vulnerability could allow an attacker to put the master station into an infinite loop, causing a denial-of-service condition. The master station (KEPServerEX runtime service) must be manually restarted to recover from the loop condition.
  • Fixed an issue with g70v3 Open File requests, where the File Size and Time of Creation fields were not being initialized properly when the request was to open a file for writing on the slave.
  • Corrected an issue introduced through a fix in server version 5.10 in which events would continue to play back when a device was in an error state. Errors other than Device Not Responding (DNR) were not being considered. When event play back is enabled and the event poll times out while communicating, the .Value and .Timestamp tags will receive BAD quality (which was the previous behavior).
  • Fixed an issue introduced in server version 5.10 where integrity and/or event polls would not occur on schedule if channel serialization was in use with many .Explicit Tags.
  • Corrected an issue where an "Initialization Completed" message would be posted when no communications had occurred with the device.

  • Added support for legacy devices that use a local time zone adjusted with time reference instead of the UTC time base in events and during time synchronization.
  • Converted the Communications device property page to a grid control.
  • Fixed an issue where processing too many continuous internal/cache tags may have delayed the processing of device tags (especially when Channel Serialization was in use and devices were not communicating).
  • Fixed an issue where a non-empty Activate Configuration Object string incorrectly triggered automatic tag generation when other device properties were modified.
  • Fixed a rare issue where an erroneous file transfer failure message could be posted along with a file transfer completed successfully message when the file transfer was successful.
  • Corrected an issue where event play back paused during TCP connection attempts.
  • Corrected an issue where event play back paused while the device was demoted.

  • Corrected an issue where event play back paused while the device was demoted.
Fisher ROC Plus Serial (5.12.140.0)
  • Fixed an issue where automatic tag generation would not create Point Types 101 through 109.
  • Fixed an issue where automatic tag generation created point types with incorrect Logical Addresses.
  • Added support for Point Types 98-x.53 through 98-x.60.
  • Added a Set/Clear indication to the beginning of the alarm strings exported via the EFM Exporter Plug-In.
GE Ethernet (SRTP) (5.12.140.0)
  • Corrected an issue that occurred when reading symbolic variables with the PACSystems model, where symbolic array and array element tags might not be included in the same request
IEC 61850 MMS Client (5.12.140.0)
  • The NIC card selected in Channel Properties is now respected by the driver. Prior to this fix, users could have encountered problems with device connectivity when selecting a non-default NIC card.
  • Updated the driver to disconnect and reconnect to devices when the NIC selection is changed while clients are connected to the server and requesting item updates from the device.
  • Resolved an issue that could occur when processing incoming data for multiple devices under a channel and result in communication deadlock
Modbus TCP/IP Ethernet (5.12.140.0)
  • Updated the driver to change the unsolicited communications timeout value from -1 to 0 (if applicable) when loading a project. This invalid value may be present in projects that were saved using older driver versions, and will invoke an error pop-up message after the Unsolicited tab is viewed in Device Properties.
OPC XML-DA Client (5.12.140.0)
  • Fixed faulty browsing logic where the driver would continue attempting to browse after an error was encountered. This could result in the driver being stuck in a loop while browsing.
  • Corrected a failure to import tags from servers that do not return the item name in the GetProperties response.
  • Fixed a defect where if the target XML-DA server returned OPC quality for an item, the driver would set the tag quality to Good during a subscription poll refresh.
Siemens TCP/IP Ethernet (5.12.140.0)
  • Added support for BOOL arrays.
Yokogawa CX Ethernet (5.12.140.0)
  • Added a check for the "EA" characters while parsing the response to the AT, AV, CM, CR, FP, and HM commands.
Yokogawa DX Ethernet (5.12.140.0)
  • Fixed an issue where writes to multiple Alarm Setpoints could result in erroneous DNR messages being posted in the Event Log.

  • Prevented a server crash from occurring when processing incoming data using Unsolicited Ethernet Encapsulation. This issue only affects Metter Toledo Serial, Modbus Slave RTU Serial, and U-CON (User-Configurable).
  • Fixed an issue where Unsolicited Ethernet Encapsulation loaded the host port instead of the source port. KEPServerEX 5.9 or older projects would break if the Port was not set to the default value (2101). This issue only affects Metter Toledo Serial, Modbus Slave RTU Serial, and U-CON (User-Configurable).
Allen-Bradley ControlLogix Ethernet (5.11.262.0)
  • Fixed an issue where synchronization failed on controllers with Firmware revision 15 or older that contained CAM_PROFILE Tags. This caused the driver to revert to and stay in Symbolic Mode.
Driver updates below coincide with Server Release V5.11.250.0 (03/05/13)
All Drivers (5.11.250.0)
Minor update to several drivers to disable the ability to show the diagnostics window if the driver does not support device level communication diagnostics. The following drivers do not support communication diagnostics at the device level: Allen-Bradley Unsolicited Ethernet, Advanced Simulator, Dataforth IsoLynx, DDE Client, DNP Master Serial, DNP Master Ethernet, GE Ethernet Global Data, GE Focas1 Ethernet, GE Focas1 HSSB, InTouch Client, Memory Based, Mettler Toledo Serial, Modbus Unsolicited Serial, ODBC Client, OPC DA Client, OPC UA Client, Simulator, Siemens TCP/IP Unsolicited Ethernet, Telemecanique Uni-Telway Slave.
ABB Totalflow Serial (5.11.250.0)
  • Improved the driver's EFM data collection performance and efficiency when intermittent communication errors are seen with the connection to the EFM data source. The optimizations are handled in the driver automatically and no project configuration changes are required in the driver UI.
  • Added DB1 as a supported Protocol Version of the driver to support G1 and early G2 Totalflow FCUs. The default setting for the driver is DB2 so users must edit Totalflow Settings to select DB1 for applicable devices in the server project.
  • Fixed an issue where the Access Type for Characteristic tags was set to Read/Write when it should have been Read Only.
Allen-Bradley ControlLogix Ethernet (5.11.250.0)
  • Added Device-level error message for Identity request failures.
  • Added project change detection support for online and offline project edits. Device setting, "Synchronize with Controller after", is available on the Logix Options property page.
  • Following a project download or edit is a period in which Logical reads/writes resort to Symbolic mode, after which the driver synchronizes with the controller so Logical reads/writes can resume. This time period has been lowered from 60 seconds to 30 seconds to improve recovery time.
    1. In the event of an "Invalid or corrupt project" error during synchronization, we now wait 30 seconds until retrying again. Before we retried immediately which caused unnecessary upload attempts and event log errors.
    2. Added support for failing a synchronization in progress as soon as a project download is detected. Synchronization will be retried after 30 seconds.
  • Fixed issue that was causing an unnecessary event log message to be posted if a project change occurs during a CIP reconnect (Idle Watchdog expires).
  • Improved logic that determines how many reads or writes can fit in a single packet, yielding a slight increase in performance.
  • Message size estimation for Symbol Instance reads was incorrect for array element blocks whose starting offset exceeded 255 (likely), making it possible to underestimate and overflow a request packet.
  • Message size estimation and generation for Symbol Instance writes was incorrect for paths exceeding 255 in size (unlikely).
  • Update for Logix FRN V21. Updated Predefined Data Types for offline ATG per Logix FRN V21:
    1. Added new pre-defined types, DATALOG_INSTRUCTION and HMIBC.
    2. Added several new members to ALARM_ANALOG, ALARM_DIGITAL, and AXIS_CIP_DRIVE per V21 changes.

DNP Master Ethernet (5.11.250.0)
  • Fixed an issue where the server could become unresponsive during automatic tag generation. This problem was introduced in the 5.10 release.
  • Fixed an issue where the driver failed to report an Event Log error message if the socket bind failed. This message failure occurred for bind failures where the protocol selected was UDP and the optional source port was set to a non-zero value.
  • Added an error message to be posted when a tag fails due to the DNP flags containing an exception condition. The error message will list the actual DNP flags byte in hexadecimal format as well as a comma delimited string listing the exceptions. An example of the message is as follows: Unable to read tag '1.0.0.Explicit' on device 'Channel1.Device1'. Device indicates one or more exception conditions (DNP flags byte='0x28' - 'Offline, Remote Force, Chatter Filter').
  • Fixed an issue where on-the-fly changes to channel properties that affect the socket did not consistently force a socket reconnect.
  • Fixed an issue where no 'Device Not Responding' message was logged and tags did not show Bad quality when the keep-alive request timed out and the project was configured with no event or integrity polling and no explicit read tags.
  • Fixed an issue where tag quality was not updated after disabling the Enable Data Collection property.
DNP Master Serial (5.11.250.0)
  • Fixed an issue where the server could become unresponsive during automatic tag generation. This problem was introduced in the 5.10 release.

Fisher ROC Plus Serial (5.11.250.0)
Improved the driver's EFM data collection performance and efficiency when intermittent communication errors occur with the connection to the EFM data source. The optimizations are automatically handled in the driver: no project configuration changes were required in the driver UI.
GE Ethernet (SRTP) (5.11.250.0)
  • Enhanced the driver to support the reading of Symbolic addresses (for PACSystems devices) via multiple blocks within a single read packet, which dramatically improves the driver's read performance in large projects. Changed the default value of the Maximum Bytes Per Request device property from 256 to 2048.
  • Enhanced the driver to support Bit-level access within Symbolic addresses within the PACSystems model selection of the driver. This change affects the following data types: BYTE, INT, UINT, WORD, DINT, DWORD, and array elements of those data types (in both discrete and non-discrete memory). Added new error messages for invalid bit index and invalid data type for bit access.
IEC 61850 MMS Client (5.11.250.0)

Lufkin Modbus Serial Client (5.11.250.0)
Fixed a minor issue where Channel level Statistics tag "_MsgResent" value was erroneously incremented instead of the "_MsgSent" count in certain situations for read attempts following a read failure. This situation could cause the "_PercentReturn" value to be greater than 100% but did not affect the value of "_PercentValid".
Omni Flow Computer Serial (5.11.250.0)
  • Improved the driver's EFM data collection performance and efficiency when intermittent communication errors are seen with the connection to the EFM data source. The optimizations are handled in the driver automatically and no project configuration changes are required in the driver UI.
  • Fixed a device password login problem that caused the driver to stop polling for data until the server runtime was restarted. The error was triggered when Ethernet Encapsulation devices returned "Exception Code 5" as a result of a login attempt with an incorrect password.
OPC DA Client (5.11.250.0)
Resolved an issue where the driver would invalidate tags if the remote server did not provide a supported data type when the item was added to the server. The driver will now wait for the first update before invalidating unsupported data types.
OPC XML-DA Client (5.11.250.0)
Initial release of a new driver used to connect to Third Party OPC XML-DA Servers.
Driver updates below coincide with Server Release V5.10.205 (11/13/12)
All Drivers (5.10.205)
Updated the driver library to prioritize a tag read following the failure of a tag write in order to expedite an update of the tag's quality.
ABB Totalflow Serial (5.10.205)
Initial release of the new driver with support for real-time and EFM communications. This release provides support for connectivity to Totalflow devices using the native DB2 protocol. The driver is a serial driver but supports Ethernet Encapsulation. The driver can be selected for installation independently or as part of the Oil & Gas Suite.
Allen-Bradley ControlLogix Ethernet (5.10.205)
  • Added support for a new service introduced in Logix FRN V21 for reading Native Tags, called Symbol Instance Addressing. Physical addressing has been deprecated for V21 but is still supported in the driver for Logix FRN V20 and below. Replaced Physical Non-Blocking and Physical Blocking with Logical Non-Blocking and Logical Blocking to encapsulate these two services.
  • Improved the demotion of tags while in an error state by increasing the number of tags failed per transaction. The driver still attempts at least one read tag per transaction to recover from the error state. This does not apply when Auto Demotion is enabled.
  • Fixed an issue where project correlation state information was not being properly reset when switching from one device connection to another which could result in that device using Symbolic mode indefinitely.
  • Resolved a buffer overrun issue where the Device ID could become corrupt if the length of the portion preceding the comma exceeded 16 characters.
  • Added an address validation check to ensure a tag's Symbolic address fits within a single CIP packet. If it exceeds a single packet, the tag will fail with "Address out of range".
  • Floats and Doubles written to BOOL, SINT, INT, DINT, and LINT Tags are now clamped in order to prevent roll-over. For example, the Float 4294967395.0 is larger than a DWord (4294967295) and would roll-over to 0. With this fix, 4294967395.0 will be clamped to 4294967295.
  • Fixed an issue that occurred when writing to BOOL and SINT Tags for Serial Gateway models.
Allen-Bradley Ethernet (5.10.205)
Added support for Communication Serialization.
Beckhoff TwinCAT (5.10.205)

    Note: A Read/Modify/Write transaction occurs when writing to a bit within a register.

  • Removed the ability for meter names to begin with an underscore, contain quotation marks or periods, or have leading or trailing whitespace.
  • EFM upload (data collection) architecture was enhanced to improve application scalability for projects containing a large number of EFM meters per poll group.
Fisher ROC Serial (5.10.205)
  • Added Electronic Flow Measurement (EFM) Support
  • Updated the driver with the new Connection Sharing feature.
  • Added a device setting to enable/disable sending a device login password.
  • When transactions fail due to an Operator ID failure, a single custom error message will now be posted per device.
  • Enhanced the driver to consume the extra bytes that may be received following a valid frame. This allows communication with ROC 300 devices, which may append an extra byte to every frame they transmit.
Fisher ROC Plus Serial (5.10.205)
  • Added Electronic Flow Measurement (EFM) Support

- Resolved an issue where the driver was failing to send closely-timed Transmit commands while using Ethernet Encapsulation.
- Fixed an obscure issue where a temporary buffer used by the state machine of one channel could be overwritten by the state machine of another channel which resulted in erroneous updates of certain tags. State machines now use independent and thread safe buffers to prevent this problem.
WAGO Ethernet (5.6.122.0)
- Fixed a deadlock issue that could cause the channel to stop communicating.
Weatherford 8500 Serial (5.6.122.0)

Allen-Bradley ControlLogix Ethernet (5.5.94.0)
- Added support for RSLogix version v19.
- Added a new check box setting in the Logix Options page of the driver called "Automatically Read String Length". When unchecked, string reads will be optimized by having the driver bypass the LEN member read and terminate the DATA string at either the first null character encountered or the maximum string length of DATA (whichever occurs first).
- Beginning with L7x controllers, an optimization in controller memory restricts that memory cannot be accessed on a non-DWord boundary or a controller fault will occur. Because the driver was not aware of this restriction, it was possible it could fault the controller while performing Physical reads or writes. To address this issue, the driver now identifies the controller and makes the proper Physical memory access.

Driver updates below coincide with Server Release V5.4.131.0 (10/28/10)
BACnet IP (5.4.131.0)
- Added support for ISO 10646 (UCS-2) and ISO 8859-1 (Latin1) character sets.
- Added a number of object properties to meet the 2008+ BACnet specification, in addition to support for simple array properties (arrays of primitive BACnet data types).
- Increased the maximum number of channels from 32 to 128.
- Added enumerated values and corresponding strings to support approximately forty new BACnet Error codes.
- Added a new error class.
- Fixed an issue wherein tags with a default client access of Read Only could not be set to Read/Write, even if Write access was allowed.
- Addendum "Add-2004-135m" specifies a small change to the way segment ACK timeouts function. Before the change, Addendum timing started at the beginning of the Request window (during which one or more segments were sent). In some cases, this caused unnecessary timeouts for larger window sizes.
- Now, the timer starts after the first segment is sent, after all the segments in the window (1 or more) are sent, or after the last segment is sent to the device.
- Modified BACnetNetworkLayer to be able to route COV notifications from a device on a different BACnet network where NPDUs do not contain the source address. Although the behavior does not appear to meet the BACnet spec, this precedent has been set by the support of other vendors. A channel property was added to enable/disable this setting. It is disabled by default (since it could degrade performance if the BACnet network has a large volume of broadcast messages).
- Modified the driver so that duplicate Device IDs are not allowed on a channel.
- Increased the COV re-subscription interval maximum value from 1 hour to 24 hours.
- Added an option for ALC devices to use a Subscriber Process Identifier (SPID) of 0. ALC devices consider all subscriptions with an SPID of 0 to be 1 subscription.
- Added an option to wait for the device to acknowledge COV cancellations. This prevents the Runtime from shutting down until all COV subscriptions have been cancelled.
Beckhoff TwinCAT (5.4.131.0)
- Added support for TwinCAT PLC version 2.9. The driver now queries the version information to determine what function codes can be used to communicate with the controller.

- Enhanced MIB parsing capabilities by providing the ability to multi-select MIBs for import, and also made the parser more tolerant of minor MIB warnings (syntax or format) that should not prevent import.
- The user is now prompted when a MIB dependency exists in both the repository and the Import target directory. If the user confirms overwriting, the repository file will be deleted and the target file will be added to the repository.
- Importing a file that is contained in the repository now causes the existing file to be deleted, and the new file added. Before, the old file was not deleted and the two files coexisted.
- Formatting change for user imported MIBs from "UserImported-<file name>" to "UserImported-<module name>_<file name>".
- Fixed an issue in the MIB Import tab of Device Properties wherein selecting "Customize" following removal of a module would re-add the previously removed module.
- Added the SNMP GetBulk command in order to read multiple OIDs from individual tables more efficiently. This is a user-selectable device property and is only used for SNMP version 2c.
- Fixed an issue wherein traps with snmpTrapOid varbinds with trailing ".0s" were not handled correctly.
- Fixed an issue with processing trap events from devices that pad the timestamp of the trap event packet with zeros.
U-CON (User-Configurable) (5.4.131.0)
- Fixed issue where projects created in server/driver version 5.3 that used WriteDeviceID and WriteEventCounter commands would fail version comparison and not load the project in 5.4.
- Fixed an issue wherein legacy .opf projects saved as xml would fail to pass schema validation.
- Modified Transaction Editor Write commands, and also added Data destination radio buttons for Read, Write, Scratch, and Global buffers for commands CmdWriteDeviceId, CmdWriteEventCounter, and CmdWriteCheckSum.
- Increased the Device ID value limit from 255 to 65535.
- The Transaction Editor posted an incorrect validation message when creating a Cache Write Value command without a preceding Transmit command. A Write Data command is required before a Cache Write Value command. A Transmit command is not required. Both the validation and error message have been updated.
- Fixed an issue wherein the driver sometimes failed to respect signed data types if the device data format had fewer bytes than the data type. Signed data types would not correctly display negative values. The driver now always respects whether the data type is signed when converting to and from the device format.
Yokogawa DX Ethernet (5.4.131.0)
- Enabled error message posting for failed write tags from a non-responding device.
- Fixed an issue wherein the driver would not properly release tag references under certain conditions. This resulted in stale tag data, and stopped further updates from being passed on to client applications.

GE Intelligent Platforms (GE Fanuc) Ethernet (V4.72.46)
- Fixed small issue with system tags where the block_num was being set such that all system tags came from the same device regardless of the actual target PLC.
Mitsubishi FX (V4.31.45)
- Added String support for D registers. The string support has been added using the same code as is found in the Modbus RTU driver. This means that a string can be formatted as either HiLo byte or LoHi byte order. The length of the string is set using the bit number field. A string can be 2 to 64 bytes long.
Modbus TCP/IP Ethernet (V4.54.39)
- Added new model for customer. The Instromet model supports three unique data ranges. The ranges have very specific memory formats. From 000 - 199 the memory format is 16 Bit Word memory. From 200 - 399 the memory format is 32 Bit DWord memory. From 400 - 599 the memory format is 32 Float memory.

- On-the-fly changes to key length did not take effect until server was restarted. We now allow the change to take effect immediately. Added suggestion to edit transaction keys in message box that is posted when this value is changed.
- Added logging of unsolicited dead time expiration, to enhance change made in version 4.00.51. This can be turned off with "Log unsolicited message timeout" channel prop.
- Fixed "Update Tag" command behavior for variable length data formats. Would post a "Buffer Bounds" error if data source was initialized and other than a scratch buffer.
- Added support for new device data format "ASCII coded IEEE float". This is not to be confused with "ASCII Real". The former takes a 32-bit binary IEEE float value and converts each of the 8 nibbles to an ASCII character. The latter represents each digit, sign, and exponent as a variable length string.
- Added new "Log unsolicited message timeout" channel mode option.
- Added registry setting that allows user to specify the maximum number of client tag updates that can be performed per tick. This setting is a DWORD value called "UnsolTagUpdatesPerTick". It can be used to reduce the total amount of time to update all tags and, depending on the protocol, can ensure client gets informed of all unsolicited data sent to driver. If setting is not present, a default value of 200 is used.
SattBus (V4.00.06)
- New Driver
Driver updates below coincide with Server Release V4.84.227
Allen-Bradley Ethernet (V4.22.25)
- Fixed toggle value issue when writing a value to a tag while a pending update is taking place.

- Fixed an L5K import parsing bug that would cause an import abort if the keyword TAG was found in a ROUTINE declaration
- Fixed data coercing bug in which bits could not be referenced for non-BITARRAY elements (ie. DINTARRAY[0]). Symptoms: Tags would be deactivated and error posted: "Data type 'Boolean' is illegal for this tag." Boolean is considered an invalid data type for non-BITARRAY elements (ie. DINTARRAY[0]) and is only valid for BITARRAY elements. Bits within a non-BITARRAY element (ie. DINTARRAY[0].0) are valid and must be Boolean.
GE SNP (V4.21.44)
- Fixed issue importing SNF descriptions that are not wrapped in quotes.
GE SNPX (V4.21.44)
- Fixed issue importing SNF descriptions that are not wrapped in quotes.

The driver has been modified with the addition of a new model to support Daniel S500 in terms of addressing and specific additions to the communications state machine for the support of a Double.
Siemens Simatic 505 Serial (V4.41.35)
- After adding the Array support as noted in the previous version, the customer like that so much they wanted even bigger arrays. The problem is the TI 505 protocol only allows for very small request for data. The user wanted a 100 word array in V memory. To do this the driver needed to be modified to allow a multi-pass read or write to occur in order to support this 100 word array.
Yokogawa Darwin Serial (V4.03.27)
- Added Ethernet Encapsulation feature to allow use of terminal/device servers.
Yokogawa CX Ethernet (V4.00.07)
- New Driver

Driver updates below coincide with Server Release V4.84.223
Allen-Bradley ControlLogix (V4.41.57)
- Fixed data coercing bug in which bits could not be referenced for non-BITARRAY elements (ie. DINTARRAY[0]). Symptoms: Tags would be deactivated and error posted: "Data type 'Boolean' is illegal for this tag."
- Boolean is considered an invalid data type for non-BITARRAY elements (ie. DINTARRAY[0]) and is only valid for BITARRAY elements. Bits within a non-BITARRAY element (ie. DINTARRAY[0].0) are valid and must be Boolean.
Mitsubishi Ethernet (V4.21.21)
- Added string support.
Modbus Ethernet (V4.44.32)
- Fixed issue with writes to output coils. When writing 1 to an output coil, which already has value of 1, client may see value as 0 until next read. This was a memory map issue - correct data was sent to device.
- Enabled initial memory map allocation feature.
Omron Host Link (V4.30.45)
- Added open addressing model.
Siemens 3964R (V4.10.20)
- "String Options" device property and wizard page was incorrectly linked to "Protocol Options" help topic.
U-CON (User Configurable Driver) (V4.00.47)

- Rebuilt with latest keplib/modem fix for customer.
- Added additional optimization of unsolicited tag update rate. Previous optimization could be partially defeated when multiple unsolicited channels were used.
- Modified tag update logic. Clients were seeing sluggish tag updates for block tags in solicited mode, and for all tags in unsolicited mode.
- Bug fix: Fixed length strings, and other formats with variable length option, would get changed to zero if an attempt to update tag from an uninitialized scratch buffer was made.

Wago Ethernet (V4.01.26)
- Fixed issue with writes to output coils. When writing 1 to an output coil, which already has value of 1, client may see value as 0 until next read. This was a memory map issue - correct data was sent to device.
- Enabled initial memory map allocation feature.
Yaskawa MP Ethernet (V4.00.05)
- Corrected potential issue with multiple bit within word writes to inactive tags.
Yokogawa DXP (V4.00.05)
- Modified login procedure for new Yokogawa DXP Style 4 firmware. Added "User ID" entry to Device Configuration.
- Also fixed issue that surfaced with Style 4 device concerning CD data reads. When Nak returned in response to CMCXX? query, the driver has timeout error instead of trapping NAK error.(Became evident in Style 4 where login with 'monitor' function instead of 'user' level prohibits any access to CD data. Style 4 firmware then would be ideally supported by invalidating CD tags, but retained in autogen and address validation for backwards compat. to Style 2.)

LinkMaster

LinkMaster Updates and Latest Version No.

Current Release LinkMaster V3.0.84.0
Copyright © 2014 Kepware, Inc.

Build Issue/Enhancement/Fix
V3.0.84.0
September 8, 2014
Runtime
- Resolved an issue where the Runtime was incorrectly shutting down following a File | Exit of the Configuration. This issue only affected the Runtime if the Process Mode was set to Interactive and no other OPC clients were connected to the Runtime's server interface.
- Resolved an issue where the Runtime could lock up if a project that had redundancy enabled was loaded.
- Updated the Runtime to respect OPC ProgID Redirect settings from KEPServerEX. Before this update, LinkMaster was unable to connect to Third-Party OPC ProgIDs that had been redirected by KEPServerEX.
- Fixed an issue where a Link Output that was not accepted by the target OPC server would keep other links from being updated.

Configuration
- Resolved several issues where Link Items in the Configuration View were not showing the status of the link correctly. When either the input or the output of the link is not functioning, the Link Item should appear gray to indicate a problem with the link.
  • Fixed an issue where Link Items displayed green if LinkMaster timed out while waiting for a Write Complete notification.
  • Fixed an issue where Link Items displayed green if a new value needed to be written and the WriteComplete notification came back with an error.
  • Fixed an issue where the Link Item did not change from green to gray when the remote OPC server was unavailable due to a lost network connection.

Build Issue/Enhancement/Fix
V3.0.75.0
April 18, 2013

Build Issue/Enhancement/Fix
V2.40.132.0
December 22, 2010
Enhancements:
- LinkMaster now allows a connection to an OPC server whose ProgID has been redirected.
- Extended the Dead Value range from 0 through 65535 to -65535 through 65535.
- Added support for LinkGroup-level CSV import/export.
- Input items will no longer be polled when "Enable Link Transfers" is disabled in the Link Group.

Fixed:
- Fixed an issue where if LinkMaster was running in Service Mode and the desktop shortcut (or System Tray icon) was double-clicked, the UI did not come to the foreground.
- Fixed an issue in which scaling was not being applied to writes in certain situations despite being enabled. This occurred when a link item experienced a write failure: retries would write the raw value instead of the scaled value.
- Fixed an issue in which a deadlock could occur when attempting to import a project-level .CSV file that contains errors.
- Fixed an issue in which changes made to the Access Path setting in the Link Item Outputs dialog would not allow users to add or update the modification unless another setting was also modified on that same page.
- Fixed an issue with the Redundancy functionality in which the Secondary LinkMaster application would not restart the Source or Target OPC server if its secondary redundancy mode (such as Warm, Cold, or Hot) was modified.
- Fixed an issue where the CSV Import removed embedded double quotes
Build Issue/Enhancement/Fix
V2.37.124.0
November 16, 2007
Enhancements:
- Added "Redundancy" feature. This feature allows a pair of LinkMaster machines to operate in redundant pairs where one LinkMaster machine operates as the "Primary" node and the other in "Secondary" mode. When the "Primary" node fails, the "Secondary" node promotes itself and takes over the role of the primary. When the "Primary" node comes back up again, the "Secondary" node demotes itself and lets the "Primary" node perform the data transfer.
- Increased name field length from 31 to 80 characters for link items and link groups.
- Added ability to disable reads in inputs when link transfers is disabled.
- Added ability to allow LinkMaster connections to itself on the local machine.
- Added link description sub-item to our link item display.

Fixed:
- Fixed issue where LinkMaster produced an anomaly when the OPC servers it is bridging are on a remote machine and the network connection on the LinkMaster machine is reset (connect/disconnect) very frequently.
- Fixed issue when adding a link item that contains a data type that is not supported by LinkMaster. The item would be removed twice, the second time potentially removing a valid item which would then break the link.
- Fixed painting issue with the item value display not updating correctly if all items in the view went to bad quality at the same time and the value was passed in as the last known value.
V2.20.108
July 19, 2006
Fixed:
- Fixed issue where we would set the link group status to bad if we receive an item update for an input prior to attempting to add the output.
V2.20.107
June 13, 2006
Enhancements:
- Added project backup capabilities. This feature will always perform a backup of an existing project file prior to overwriting the file. This option can be turned on through the Tools|Options|General menu item. 

Fixed:
- Fixed issue where we would send a write to an output on the first update of the input, regardless of whether or not the quality associated with the input was good.
- Fixed issue with returning OPC array data to remote clients over DCOM when acting as an OPC server.
- Fixed issue where we would send a bad quality write to an output if the addition of the output item(s) occurs after we originally receive the bad quality input update.
- Fixed issue where we could send a write to an output if the input server returned a value with good quality, but also included a failure code to indicate the VQT could not be set appropriately.
- Fixed issue where you could not close message boxes invoked from either the link group or link item property dialogs.
V2.10.102
October 18, 2005
Enhancements:
- Added support to retry AddItem requests to underlying OPC servers that previously failed the AddItems request. These are retried at a user-specified interval under Tools|Options|Links.
- Added support for user to control how the application window is displayed when started by a client or minimized to the task tray. These settings are located under Tools|Options|View.
- Added ability to select whether or not the application should retry writes to outputs that return a write complete failure. By default we will retry writes as this has been the default behavior prior to this feature.
- Added support for Boolean arrays.
 
Fixed:
- We no longer allow users to make modifications to a project during an import CSV operation. This should have been the case in earlier releases. This prevents painting issues caused by this condition.
- Fixed issue where LinkMaster would send repetitive Asynchronous Read requests without waiting for the previous callback to be returned from the underlying server(s). This would cause unnecessary memory usage in the server(s) and increase network traffic if used over DCOM. This issue only affected projects that had set a 'Client I/O Refresh Rate' on one or more link groups.
- Fixed issue where the Toolbar and Status bar state was not properly saved when the application is shutdown and the window is minimized.
- We now place double quotes around all CSV export fields that contain string data. This allows the application to re-import the same or modified CSV that contained characters that affected the parsing of the CSV file (e.g., commas).
- Fixed performance issues when importing a CSV project that references machines and/or OPC servers which are not available but are referenced in the CSV configuration.
- Fixed the scaling write issue where an unscaled write would be sent down initially followed by a scaled write, when scaling was enabled and the underlying OPC items were initially added or re- Added due to configuration changes.
- Fixed issue with improper 'status' icon updates for link groups/items that contain outputs that failed the add item request. In this case, the icon displayed next to the link item would still show as green vs. gray.
- Modified the Quick Browse window to no longer be a TOP MOST window, so that when another application's window is selected, it will fall to the background along with the main LM window.
- Fixed anomaly that could occur while the Quick Browse window is displayed and the user obtains access to the LinkItem property dialog (by right-clicking on the application title bar located on the task bar) and issues a close.
- Fixed issue that could cause the application to hang if the user attempts to terminate the application while it is in the middle of opening or closing a project.
- Fixed issues which delayed the application from terminating in a timely fashion when the project being closed is currently attempting to connect to unavailable machines/servers.
- Fixed array write marshalling issues that could occur on some systems.
- Fixed link item status issue not reporting that it failed to write to an output item that belongs to a machine or server that is unavailable.
- Modified browse filter to use "*" rather than a null string. Some servers do not return all leaves when sending a null string.
- Fixed item browser paint issue that occurred if a server returned leaves with no fully qualified item ID.
V2.00.89
March 25, 2005
- Fixed issue where we would not write to link item outputs after receiving a shutdown notification from the server (which owns the outputs)and performing a successful reconnect to the server. This only occurred when write optimizations was set to send last update only.
- Fixed issues with not being able to change the machine name on the fly for link item input or output when editing the machine name, rather than selecting something from the drop down control.
- Fixed issues with repainting the Quick Browse view if we lose communications with a server displayed in the view.
- Fixed anomaly that could occur if LM is shutdown while there is 1 or more event viewer connections outstanding.
- Fixed issue where dead value would not get sent to clients and LM link view pane until server reconnect attempt complete. This could take 2 or more minutes if reconnect resulted from network problem. Updates are now immediate upon detection of connection propblem.
- Fixed issue where full connection with remote servers could not be established after a temporary network failure.
- Added INI File option "Always Browse Servers From Local Machine". This allows LM to connect to OPC servers running on remote machines that cannot run opcenum.exe. The servers must be registered on the local machine, and local machine must be running opcenum.exe.
- Enhanced service mode operation. No longer need to start and stop from service manager. Can access from system tray.
- Fixed issue where dead value was not being sent to link output items.
- Fixed issue where extended demo periods (60 day or longer) were not being honored.
- Fixed issue where "Unknown quality" would be displayed in property view if limit bits (in OPC Quality value) were non-zero.
- Fixed issue where items with unsupported data type would not be removed correctly.
- Added Date data type.
- Added license number field in Help/About dialog.
V1.21.76 - Added support for creating Custom Remote Machine references for machines/devices that do not expose themselves through a 'network neighborhood' interface. (76)
- Fixed issues with not properly reattempting to establish connections to server(s) if the initial connection partially succeeds (i.e., connect to opcenum succeeds, connect to server fails). (75)
- Fixed issues with not properly re attempting to establish connections to server(s) if the initial connection attempt fails. (74)
- Fixed byte alignment issue between DDE layer and application layer that was introduced when dead band took scaling into account. (72)
V1.18.71 - Fixed ability to connect to remote inprocess servers.
V1.17.66 - Fixed default project open/save paths to be <product installation>\Projects.
- Fixed window flickering issue when performing any operations which invokes a busy dialog.
- Added necessary logic to utilize dead banding on scaled values to work with the latest OPC library.
V1.16.64 - Fixed object pointer validation (OPC Layer) to check to see if we have access to the specified memory location, prior to check in the object signature.
V1.13.60 - Fixed issue with browsing internal groups from a client.
V1.12.59 - Increased wait to restart period from 5-30 seconds to 5-600.
- Fixed issue with properly observing the restart period.

3. Fixed write dialog repainting issues when a write field edit box is selected and you resize the column headers.
4. Fixed issue with auto-generated projects that contain tag names that are maxed (or close to max) out in length.
5. Moved all asynchronous refresh operations to the group menu level where they belong. They were previously at the item menu level. 6. We now prevent the user from changing the group update notification if the group is connected to the server, since this is not allowed to be an on-the-fly change.
7. Reworded browse dialog access rights values from Any/ReadOnly/WriteOnly/Read/Write to Any/Readable/WriteAble/R and/or W for clarity on what the server is returning in accordance with the 2.05a specification.

Build Issue/Enhancement/Fix
V1.10.54
November 23, 2005
  • Added ProgID Aliasing to allow redundancy to be provided to multiple pairs of servers with the same ProgID.
  • Fixed anomaly that occurred when sending an e-mail notification to an SMTP address that specified a DNS name with 'dots' in the name. The application was treating this as an IP address which resulted in a runtime anomaly. (SWTB)
  • Fixed issue with properly updating DCOM configuration when uninstalling as a service.
V1.10.54
November 23, 2005
  • RedundancyMaster will now send IOPCShutdown notifications to clients when the application is terminated by an end-user.
  • Fixed anomaly that occurred when sending an e-mail notification to an SMTP address that contained dots in the address, but was not in the form of an IP address.

V1.01.41
January 07, 2005
We now properly apply the 'Notifications' settings prior to sending a test e-mail.
V1.00.38
December 20, 2004
Initial Release - V1.00.38
  • Fixed issue where -unregister would not uninstall application as an NT service.
  • We no longer post the default monitor item dialog validation box for 'Specific Time Period' trigger.
  • Fixed ability to manually enter in a larger monitor item failure count in the xml file then the number of monitor items defined.
  • Removed monitor test interval, as this can be automatically calculated by the runtime. There are built in precautions so that we do not fail a monitor item test until we receive an initial update on the item.
  • We now force the 'No item changes for a given time period (ms)' trigger data to be at least 2 times the update rate associated with the monitor item. If the trigger data is less an informational prompt notify the user that the value was auto-adjusted will be displayed. Also, care was taken when loading the XML file to enforce this in case it is changed outside of the configuration utility.
  • When a monitor item can not be added, it will now be considered in error.
  • We now prevent entering trigger data that contains non-numeric characters, is empty or is set to less than 10ms for the "Specific Time Period" condition.
  • Fixed the ability to maintain the active connection appropriate machine (primary or secondary) when changin the machine names on the fly in cold mode.
  • Made modification so that there is always a new monitor test after reconnecting to a server.
  • Fixed ability to change machine name on the fly.
  • Fixed repetitive Connect/Disconnect messages when we can successfully connect to the server and call methods, but the server can not initialize a callback back into us.
  • Added ability to save diagnostics to a text file.
  • Added ability to set an update rate on a monitor item.
  • Added support to fallback to 1.0 interfaces for monitor items.
  • Fixed proper assignment of diagnostics events when switching between servers.
  • Added necessary logic to send clients bad quality updates for items when a connection to both primary and secondary servers is lost or can not be made.
  • Fixed issue which would allow a process to unload our runtime dll even if we providing services for the process.
  • Added 'Date' data type support.
  • Added the ability to import the necessary OPC server configuration from a remote machine.
  • Added registry modification log when enabling/disabling redundancy on server(s).

  • Added the new status code E_Timeout.
Build Issue/Enhancement/Fix
ClientAce
V4.0.2.2
07/16/13
  • Added support for the .NET 4.0 Framework in Visual Studio 2010 and Visual Studio 2012.

  • Added support to the ServerBrowser Control for OPC UA server browsing via Local Discovery Servers.
  • Added support to the ItemBrowser Control for OPC UA server connection and OPC Item browsing.
  • Added support for UA user authentication through the passing of username and password credentials to the OPC UA server.
  • Updated the Kepware-specific ServerState Control. There are now two controls: one for OPC DA and one for OPC UA. The Server Project Name field was removed from the control, and the Server Project Title field was added.
  • Updated the Kepware-specific ChannelSetting Control. There are now two controls: one for OPC DA and one for OPC UA. The controls were updated to support the new channel and device properties that were added during updates to KEPServerEX V5. Newly supported fields include Pending Reads/Writes and Max Pending Reads/Writes for diagnostics, Media Level Redundancy monitoring tags, device-level diagnostics tags, Scan Modem, and Ethernet Encapsulation.
  • Added support to the ClientAce API that allows ClientAce applications to be developed as OPC XML-DA clients.
  • Made an enhancement that allows users to force ClientAce to only use the OPC 3.0 IOPCBrowse Method or the OPC 2.0 IOPCBrowseServerAddressSpace Method. In the default setting, the ClientAce API queries the OPC Server to determine the OPC specification it supports and then uses the appropriate browse method; however, some OPC servers do not properly indicate the specifications that they support.
  • Added support for the IOPCCommon::SetClientName Method. For servers that support this on the OPC interface, this method allows a client application to identify itself to the server application in addition to the ClientID. Support for IOPCCommon::SetClientName was added to KEPServerEX versions 5.7 and later.

  • Changed how messages are batched. They are now bundled according to the client update rate with no hard limit. Prior to this change, messages were inefficiently sent to clients in batches of 10.
NIO
V5.15.585.0
07/22/14
  • Added an option to the iFIX PDB Settings page to allow updates to PDB clients even if the value and quality of the tag does not change. This allows the iFIX PDB client to receive the freshest timestamps.
OPC DA Server
V5.15.585.0
07/22/14
  • Fixed an issue where the server would invalidate tags that returned UNCERTAIN quality. This issue was limited to client drivers (such as the OPC DA Client Driver and the OPC XML-DA Client Driver).
OPC .NET Service
V5.15.585.0
07/22/14
  • Fixed an issue where the server was not properly releasing client connections when the client terminated abnormally. Clients and their tag references are now removed on a timeout.
OPC UA Server
V5.15.585.0
07/22/14
  • Fixed an issue introduced in KEPServerEX version 5.12 where dynamic tags were not allowed.
  • Fixed an issue where source and server timestamps were being reversed in the update sent to clients.
  • Fixed a memory leak. Prior to this fix, when monitored items failed to be added to a subscription, additional space was created for them to retry. This resulted in a steady increase in memory in the case where monitored items were invalid and failed every addition. With this fix, the existing space is re-used.
Advanced Tags
V5.15.585.0
07/22/14
  • For the On Input Value Change (Ignore Initial Update) trigger, BAD quality is no longer considered a change of value and is ignored. This was done to ensure that the initial update is ignored whether it is good or bad quality.
  • Enhanced Derived Tags to allow string comparison using the equals (==) operator.
  • Fixed an issue where advanced tag trigger expressions that used string tags were not working properly.
DataLogger
V5.15.585.0
07/22/14
  • Reorganized the Triggers dialog to be more intuitive. The start/stop logging options were moved to the Absolute and Expression trigger type pages. The Log on Static Interval and Log on Data Change logging options were moved to a new Logging Conditions page.
  • Added a new trigger condition that allows a snapshot to be taken of a log group's current tag values when a monitored item changes. A deadband can be applied to the monitored item to control how often a snapshot occurs.
  • Fixed an issue where enabling a log group could cause false triggers in some trigger expressions that included server tag data. In these cases, the tags failed to get an update before the trigger expression was checked, which caused the check to return true incorrectly.
  • Fixed an issue where a negative value was shown for the log group's Update Rate (located on the Data Map tab) if the Update Rate was greater than 24 days.
EFM Exporter
V5.15.585.0
07/22/14
  • Fixed an issue in the "File Path" buttons that prevented the root path from being opened when |SystemX| wildcards were used in the path.
  • Fixed an issue where edits applied to a Poll Group that was in the process of polling were discarded.
  • Fixed an issue in V7 CFX files where the start/end times defined in the file were incorrect if the file didn't contain hourly or daily data. The times now represent the span of time between all poll results, including alarms, events, history, and batch.
  • Removed a false error message that could occur when device communications were lost or the EFM meter had no new data. The error message was "Warning EFM Exporter Unable to read EFM data from temporary file."
Build Issue/Enhancement/Fix
OPC AE Server
V5.14.491.0
02/18/14
  • Fixed a failure found in the server when running the OPC Foundation's Compliance Test Tool (CTT). Setting a subscription filter will now return "E_INVALIDARG" instead of "S_FALSE" when invalid sources and areas are set in the filter. The call will fail and the filter will remain in its previous state.
  • Clients can now acknowledge an alarm from a refresh event. The refresh event has the same cookie and timestamp as the original alarm, which allows clients to use it for acknowledgement. This is a change in behavior with respect to existing clients. Previously, refresh events had unique cookies and the timestamp was the time at which the refresh event was generated.
OPC .NET Service
V5.14.491.0
02/18/14
  • Fixed an issue where the interface would not start because of a failed Certificate Revocation List check. The server previously mandated that the check be online, which required access to the internet.
SuiteLink/FastDDE
V5.14.491.0
02/18/14
  • Added a message to the Event Log to indicate when an invalid topic is added by a client.
OPC UA Server
V5.14.491.0
02/18/14
  • Fixed a memory leak that could occur during writes with certain clients.
Advanced Tags
V5.14.491.0
02/18/14
  • Enhanced Link Tags to have the new trigger mode option On Input Value Change (Ignore Initial Update). This mode is identical to the existing On Input Value Change option, except that the initial update does not cause the Link Tag to write to the output. This is useful when the initial value in the Input Tag is not required or meaningful.
  • Fixed a Link Tag issue where the output would not get updated if the input read returned too rapidly, as seen with internal or simulated tags.
  • Updated the XML schema to allow for tag descriptions up to 255 characters. Corrected the size of the address field to be 1024 characters.
DataLogger
V5.14.491.0
02/18/14
  • Added support for store and forward. Log groups can now store data locally to disk when connectivity to the SQL server is lost, and then forward the data when connectivity returns.
  • Fixed an issue where performing a CSV export would disable the Apply Changes button without applying the changes to the Runtime. Now, performing a CSV export causes the changes to be applied and disables the Apply Changes button.
  • Fixed deadlock that could occur if Link Tags were linked to DataLogger System Tags. The deadlock occurred when starting a log group.
EFM Exporter
V5.14.491.0
02/18/14
  • Added support for exporting Liquid EFM Data to Flow-Cal V7 CFX files. Liquid support works with the OMNI, ROC+, and EFM Simulator drivers only.
  • Fixed an issue where EFM data could be lost if the configuration upload failed.
  • Fixed a bug in the CFX V5 configuration serialization. The previous implementation picked the wrong K factor unit depending on whether the unit attribute was set to metric or English.
  • The EFM Exporter now posts warnings when changing the CFX V7 or V5 history interval if there is un-exported data on disk. This data will not be exported unless the change is reverted.
  • Added an Open Export Path button to the Flow-Cal, CSV, and PGAS exporters. This button will open the export directory path in a file explorer window.
  • Corrected the tab order in the following EFM Exporter dialogs: CSV Config, Event, Alarm, and History; EFM Meters; and Flow-Cal Exporter.
  • Fixed an issue where EFM uploads would fail to complete if the block size of a device being polled was changed during the upload.
Build Issue/Enhancement/Fix
OPC UA Configuration Manager
V5.13.191.0
10/15/13
  • Changed the import validation of the certificate's Common Name (CN) Subject field. Now, both root and intermediate Certificate Authority (CA) certificates can be successfully imported without a CN field.
Beckhoff TwinCAT Remote Manager
V5.13.191.0
10/15/13
  • The server installation no longer provides a copy of TcAdsDll.dll or the Beckhoff TwinCAT Remote Manager Utility. User must obtain the TwinCAT ADS Communication Library from Beckhoff in order to access the tools that are required to configure successful AMS Remote Connections.
NIO
V5.13.191.0
10/15/13
  • Resolved an issue with 4BCD Signal Conditioning where a data type mismatch caused data to be replaced with the value zero.
OPC DA Server
V5.13.191.0
10/15/13
  • Added the new "Ignore group update rate" OPC Compliance setting for use with the new Device Demand Poll feature available in this release.
  • Changed how initial updates are handled for active items that are added after a group has already returned initial updates for all other items. The previous implementation would wait for update interval expiration. The new implementation generates an off-schedule update in order to supply initial values as soon as they are available. Both ways comply with specifications, but the new implementation makes the server more responsive to the client. It also corrects issues that occur when initial updates for some items are delayed until the expiration of the first update interval (when the server is not configured to return all initial item updates in a single callback). The new implementation passes OPC DA 3.0 compliance 1.18.0.1168.
  • Fixed the unhandled exception that resulted when a client removed the server reference while there were still references to a group or groups.
SuiteLink/FastDDE
V5.13.191.0
10/15/13
  • Fixed an issue where tags could fail to update while using Wonderware Redundancy after switching back to the primary. When this occurred, Wonderware SMC would post the error message "Invalid point type returned from CreatePoint."
EFM Exporter
V5.13.191.0
10/15/13
  • Enhanced the EFM Exporter to support exporting to ODBC data sources. Users can now choose the Data Source Name as well as the destination tables for Configuration, Alarms, Events, Daily, and Hourly History data. The UI also allows users to easily define mappings between EFM attributes and table fields.
  • Fixed an issue where CSV import incorrectly allowed invalid characters (such as a leading underscore) in the exporter's Name field.
  • Fixed an issue where changes to the exporter's Name field did not take effect until the Runtime was reinitialized.
  • Added name validation to the XML schema for all exporters and the Poll Group.
  • Fixed the failure to import the Poll Group's CSV file.
  • Fixed the N-C4 and ISO-C4 name strings.
  • Fixed the Alarm State's description string.
  • Fixed the Daily History property page's help link.
  • Resolved an issue where changing the polling from OnDemand to Scheduled (or vice versa) would not take effect until the Runtime was reinitialized.
  • Resolved an issue where changing the polling from OnDemand to Scheduled on-the-fly after the first scheduled poll had already completed would result in an immediate poll. The Event Log message from the immediate poll would show a next poll start time that was earlier than the time that the immediate poll was started.
  • Resolved an issue where disabled exporters would be re-enabled after the poll method was changed and the Server Configuration was closed and reopened.
SNMP Agent
V5.13.191.0
10/15/13
  • Enhanced the plug-in to include trap descriptions as a varbind in the trap payload. Network Management applications should now be able to decipher traps with human readable descriptions if the trap receiver is unable to take action based on the Trap OID reference alone. This enhancement includes the addition of the new "lastTrapDescr" system object. The object's value is the description of the last sent trap. Network Managers can use the system object to poll the SNMP Agent and determine the last trap that was sent. The MIB export feature has also been updated to reflect these enhancements.
Build Issue/Enhancement/Fix
DataLogger
V5.12.142.0
08/05/13
  • Resolved a DataLogger issue introduced in KEPServerEX version 5.12.140.0 where values for columns associated with the first log item in the Server Item List were incorrectly logged as NULL. This issue affects customers who upgraded to version 5.12.140.0 from an earlier server/plug-in version and use the Wide Table Format to log data.
OP UA Configuration Manager
V5.12.140.0
06/18/13
  • Increased the maximum number of configurable endpoints to 100.
  • Display an error message in the Add/Edit Endpoint Definition dialog to prevent users from configuring more than the maximum number of endpoints.
  • Note: A UA endpoint consists of a URL, security mode, and security policy. It is possible to configure more than one UA endpoint in the Add/Edit Endpoint Definition dialogs.
OPC UA Server Interface
V5.12.140.0
06/18/13
  • The OPC UA Server now retains the user credentials that are passed by the client in order to activate a session. This identity is used to apply access control permissions that are defined in the User Manager.
  • Note: Once an authenticated UA session is established, the UA Server can drop the connection if the user credentials associated with the active session are invalidated because the server user has been disabled. This functionality does not require the server to restart or reinitialize.
DataLogger
V5.12.140.0
06/18/13
  • Resolved an issue where DataLogger could miss or duplicate data entries under certain conditions (such as when receiving a new item update from the server while still processing or logging a previous item update).
  • Added a Batch Identifier enhancement that allows users to select a tag as a "Batch Identifier" and then map it to a database column. When a database transaction is triggered, the current value of the Batch ID tag will be written to Batch ID column for all rows in the transaction.
EFM Exporter
V5.12.140.0
06/18/13
  • Fixed a defect that would have prevented users from changing the name of a new CSV Exporter.
License Activation Utility
V5.11.250.0
03/05/13
  • Resolved an issue where the License Utility could stop running if launched on certain PCs. The issue was reported by a customer using a 64-bit Windows 2008 PC configured to use a language selection of Korean. The root cause was an invalid method used (by the utility) to de-allocate string memory.
  • Improved support for RAID hard drives, virtual environments and Operating System configurations.
OPC UA Server Interface
V5.11.250.0
03/05/13
- Fixed an issue where the UA service "FindServers" returned the incorrect endpoint when multiple endpoints were configured. Additionally, the service now correctly handles URLs with mixed case, URLs that exclude the domain postfix, and "localhost" URLs.
Advanced Tags Plug-In
V5.11.250.0
03/05/13
- Resolved an issue with the Add Tag dialog, wherein selecting a system keyboard shortcut (such as Alt+F4) could cause the Configuration to stop running.
Alarm & Events Plug-In
V5.11.250.0
03/05/13
- Resolved an issue with the Add Area dialog, wherein selecting a system keyboard shortcut (such as Alt+F4) could cause the Configuration to stop running
DataLogger Plug-In
V5.11.250.0
03/05/13
- Resolved a minor issue where the UI portion of the Server Item List from the Data Map tab did not immediately display items following an Import from CSV.
EFM Exporter Plug-In
V5.11.250.0
03/05/13
  • Enhanced the EFM Exporter to support the following new System Tags for use in SCADA client applications:
    • _Enable – enable or disable a Poll Group, Meter, or Exporter.
    • _ErrorOnLastPoll – true if there was an error on the last poll, otherwise false.
    • _LastPollEnd – the date and time (in UTC) the last poll completed.
    • _LastPollStart – the date and time (in UTC) the last poll started.
    • _NextPollStart – the date and time (in UTC) of the next scheduled poll.
    • _Polling – true if the Poll Group is currently being polled, otherwise false.
    NOTE: The _Enable System Tag was added at the Poll Group, Meter, and Exporter levels while the remaining tags were added at the Poll Group level only.
  • Altered the default path for Flow-Cal, PGAS, and CSV exporters to make them more user-friendly. The new path is:
    <user_profile_dir>\EFM\|PollGroupName|\|ExporterName|\|RecordYear|\|RecordMonth|\
  • Added vertical scroll bars to the export file edit boxes for all exporters.
  • Windows registry persistence was added for the Export File Path and Name properties of the Flow-Cal exporter. This behavior is consistent with the CSV and PGAS exporters.
  • Reduced memory use when dealing with large .CFX files.
  • Fixed an issue where all records of the current export file contained the current device timestamp when the data included from the previous record should retain the previous timestamp.
  • Made temporary meter data files persist through power loss. As a result, if the user changes the configuration before a result file has been consumed, its corresponding temporary file will not be deleted. A new event log message "Failed to remove temporary meter data file", with reason "Configuration change" will inform the user when this happens.
Media Level Redundancy
V5.11.250.0
03/05/13
- Resolved an issue with the Device Browser dialog, wherein selecting a system keyboard shortcut (such as Alt+F4) could cause the Configuration to stop running.
Build Issue/Enhancement/Fix
FastDDE/SuiteLink Interface
V5.10.205
11/13/12
- Fixed an issue where the server would add duplicate Topics and Items under certain circumstances where network connectivity issues were observed. Because the client doesn't inform the server about connection loss, it never gives the server a chance to release the resources associated with the lost connection. When updating the client, this causes an increase in memory consumption and a decrease in performance. By checking for duplicates when new item references are added, this situation may be avoided.
OPC AE Server Interface
V5.10.205
11/13/12
- Fixed a defect where adding a Condition to a Source that has Bad Quality could have resulted in an Event before the Alarm is started. The Alarm already has a check for this condition on Value Change. The same check was implemented on Quality Change.
OPC DA Server Interface
V5.10.205
11/13/12
- Resolved an issue experienced by a customer that was using a custom OPC client application where the server was producing two updates for each item's initial update following addition to a group.
- Addressed the cache refresh that was returning Bad Quality for items that had not yet received an initial update.
- Fixed an issue where the incorrect item time was being returned to the client when querying item properties. The time was being returned as local time, but should have been returned as UTC in a variant (using the VT_DATE type).
Connection Sharing
V5.10.205
11/13/12
- Initial release of the Connection Sharing feature, which is contained within a plug-in that is selected by default in the installation. The Connection Sharing feature allows two serial drivers to share a single communication port or dial-up modem. It is intended for use in Telemetry applications where drivers need to "take turns" polling for data over shared hardware. In addition to the new views available when the Channel/Devices View is displayed in the server Configuration, the maximum range for serial communication ports was increased to 999.
EFM Exporter
V5.10.205
11/13/12
- Enhanced the EFM Exporter to support the following export formats:
  • PGAS v8.0
  • CSV
- Fixed an issue with the Flow-Cal Exporter where 63 character string type events and alarms were being read back improperly from a cached CFX file, causing the events or alarms that followed to be loaded incorrectly as well.
- Changed the Flow-Cal Exporter's default file path to include |PollGroupName| and |ExporterName| wildcards like the PGAS and CSV exporters.
- Altered the mechanism that deletes the Flow-Cal Exporter's temporary cache after loading its contents into memory to call ::DeleteFile instead of CFile::Remove (which simply calls ::DeleteFile and throws an exception on failure). Failure can occur if the file is locked by another process. Users will see an error/event message, and the other exporters defined in the same poll group will not be skipped.
- Added the "argon" and "specific_heats" mappings to the Flow-Cal Exporter's Event Mappings.
- Fixed a defect in the 5.9 release that failed to load Flow-Cal Exporter XML paths containing wildcards.
- Resolved an issue with the Add Multiple Meters dialog, wherein selecting a system keyboard shortcut (such as Alt+F4) could cause the Configuration to stop running.
Build Issue/Enhancement/Fix
iFIX PDB/NIO
V5.9.170
06/26/12
- Added the new "Use iFIX Startup Configuration File" setting, which allows iFIX users to enable or disable a special iFIX configuration file that is used by the server to automatically start scanning items before iFIX requests item data.
OPC DA
V5.9.170
06/26/12
- Fixed an issue where the server set errors for individual properties in the "IOPCItemProperties::GetItemProperties ()" call to "E_FAIL" rather than to "OPC_E_INVALID_PID".
- Fixed an issue where two updates occurred for each tag that was added to a group on an initial update. This could occur if a client requested an "Advise" on a group before any items were added and subsequent active items were then added to the group.
DataLogger Plug-In
V5.9.170
06/26/12
- Added the new "Item data set to good quality" Event Expression trigger to the Start and Stop condition pick lists.
EFM Exporter Plug-In
V5.9.170
06/26/12
- This new server plug-in allows the export of Electronic Flow Measurement (EFM) data from EFM-enabled drivers. At this time, support is for EFM export to Flow-Cal format (CFX) Versions 5, Report Types 1 through 4.
Advanced Tags Plug-In
V5.9.170
06/26/12
- Fixed an issue where XML project files created from previous versions of the server failed to load.
- Fixed an issue where the Average Tag value was reset when the Data Tag or Run Tag was bad quality.
SNMP Agent
V5.9.170
06/26/12
- Fixed an issue where using the '%' character in the Community string name would reformat the name and make it unreadable in the Event Log when used as part of an Event Log message.
Build Issue/Enhancement/Fix
FastDDE/SuiteLink

V5.6.122.0
07/25/11
- Added several enhancements that include the following:
    • Deadband support for logged items.
    • An optional NumericID field for logged items.
    • Ability to use Start/Stop Snapshots without requiring that Log on Static Interval or Log
       on Data Change Trigger Behaviors also be enabled.
    • New System Tag "_LogDataBit" that allows client applications to trigger DataLogger.

07/25/11
- Added more detailed error reporting when MOC connections fail due to an invalid table.
- Made the name of the MOC table user-configurable.
- Added a check to prevent loading an .xml-based project if the Time Zone entry is not valid.
SNMP Agent
V5.6.122.0
07/25/11
- Added CSV Import/Export.
- When a Get request is received and the tag quality of an item mapping is Bad, the "NoSuchObject" exception will be returned for SNMPv2c. A "NoSuchName" error status and index will be returned for SNMPv1.
- When a Get-Next request is received and the tag quality for an item mapping is Bad, the OID will be skipped and the next enabled Good quality tag will be returned.
- Excluded Counter64 objects from SNMPv1 MIB exports. Counter64 objects are now treated as invisible to SNMPv1 Get-Next requests.
- Updated the XML Schema to include a choice for resolution/rate data.
- Updated the Agent (per RFC1157) to discard and not respond to SNMP-Set requests that do not contain a valid read/write Community.
- The Agent will now completely disconnect communications when disabled from the UI.
- Resolved an issue where the "agent-addr" field in V1 traps would be set to "255.255.255.255" instead of the IP of the Network Adapter. This occurred when the Network Adapter was set to "Default".
DDE/Advanced DDE

V5.5.94.0
02/18/11
- Fixed an issue where an incorrect value was being returned from IOPCServer::GetErrorString() following the successful loading of an expected string. This issue caused the server to fail the OPC DA 2.05 compliancy test.
- The timing settings located in the "OPC DA Settings" Project Properties tab now correctly check for and disallow out-of bound values.
- A new OPC compliancy setting has been added. When set True, it will cause the server to return S_FALSE in the item error array for items that have non-good quality. The new setting defaults to True for existing projects that are set to full compliance, and False for those that are not. When set False, the legacy behavior of returning E_FAIL (0x80004005) will occur.
- Fixed crash uncovered during interoperability testing with COGENT's OPC DataHub.

- The tag creation GUI now allows multiple tags to be created from the same instance of the tag editor.
- Fixed failure to reject reads on inactive tags (i.e. tags that are not started).
- Scaled tags in derived expressions are now handled properly. Previously the device data type rather than the engineering data type was being used for expression evaluation which would result in a failure to evaluate expressions even if the scaled data type was valid.
- LBCD and BCD data types are now allowed in derived expressions as they were in 4x. The server treats data from these types as DWORD and WORD respectively.
- Added support for the F1 button to bring up the Advanced Tags help file when Advanced Tab is selected.
- Fixed a bug where a complex tag with no complex elements failed to load when saved in XML. We were not serializing the element list for this case which is required by the schema.

06/09/10
- Fixed an OPC DA 3.0 issue with the "IOPCBrowse" interface where the server was not returning the correct HRESULT if one or more of the item properties could not be retrieved. The correct behavior is to return "S_FALSE" in this case instead of always returning the HRESULT from GetProperties() for the last leaf item in the browse item set.
- Fixed OPC compliance issue with reads in situations where the system clock is not monotonically increasing.
- Fixed failure to return device data following async read from device. Problem is exposed when deadband is enabled on the item that is being read.
UA Server Interface
V5.3.118.0
06/09/10
- Fixed incorrect deadband logic where we were updating the UA cached value regardless of whether the update passed deadband. This was causing a failure to update clients if the value incremented past the deadband limit.
