KEPserver to KEPServerEX upgrades

Build	Issue/Enhancement/Fix
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.
V4.264.401 (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 other 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 (8/12/05)	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 (5/19/05)	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 (3/15/05)	- Incorporated driver update for Siemens TCP/IP Ethernet and new drivers.
4.160.316 (2/11/05)	- Added support for auto-demotion of a device for most drivers.
4.150.304 (9/9/04)	- 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.
.297	- 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.
.293	- Fixed general issues with scaling BCD and LBCD array types. - Fixed scaling precision issues when dealing with raw BCD and LBCD data types.
.287	- 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)
.274	- 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.
.270	- Library fix for all drivers.
.269	- Added OPC Diagnostics Tool. - Fixed proper clean-up of tags when a client disconnects in an improper fashion.
.260	- Intellution NIO - Added support for AR and DR registers.
.252	- Fixed Dead band issue when applying to scaled values.
.251	- Fixed Default project path on new installations. - Fixed issue with setting the modify bit appropriately when modifying custom channel properties.
.241	- Fixed minor cosmetics to the GUI.
.239	- Added timestamp to diagnostics when copying to the clipboard.
.237	- 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.
.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.
.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.
.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.
