ClientAce

Install

• Updated the ClientAce binaries to version 4.0.2.6.
• Added support for Visual Studio 2013 IDE.
• Added the following new examples:
  • Simple ClientAce OPC DA VS2010-12 Event Example_VB
  • Simple ClientAce OPC DA VS2010-12 Event Example_CS
  • Complex ClientAce OPC DA VS2010-12 Example_VB
• Tested support for the .NET 4.5 Framework.
• Added installer and files for the Visual Studio 2010 C++ Runtime and OPC Foundation Core redistributables.

ClientAce Binaries

• Corrected an error that caused AsyncWrite to sporadically throw IndexOutOfBounds exceptions.
• Corrected an error that caused OPC UA Connect to hang when the targeted server either did not support or had not enabled the security settings specified in the ConnectInfo object.
• Fixed the ReadCompleted and WriteCompleted callback functions so that they return results for each item even if there is a timeout while performing the Read or Write actions (or if the complete operation failed).
• Added the new status code E_Timeout.

• Added support for the .NET 4.0 Framework in Visual Studio 2010 and Visual Studio 2012.
• Added support to the ClientAce API that allows ClientAce applications to be developed as OPC UA Clients (for DA Information Models only). ClientAce supports all OPC UA security levels, direct connections to endpoints, and browsing for endpoints via Local Discovery Servers.
• Added support to the DA Junction that allows users to connect to OPC UA endpoints directly or to browse for local OPC UA endpoints via Local Discovery Servers.
• 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.

• Updated the libraries to version 4.0.2.7.
• Added support during installation for Roaming Profiles with remote servers. Add-in Install location is now relative to the target directory selected during installation and is visible within Visual Studio's Add-in Options. Some users may be required to uninstall the product before upgrading to remove any Add-ins previously installed in the default location.
• Added new properties to the ConnectInfo class that support configurable timeouts for UA Service calls and adding read/write groups with active items.
• Updated DA Junction control to sample at the same rate as the publishing interval instead of sampling as fast as possible.
• Fixed an issue where the revised update rate was not set when creating a subscription on an underlying OPC UA server.
• Corrected an error causing an exception when removing a server through the ServerBrowser control.
• Fixed a memory leak with applications using the asynchronous methods ReadAsync / WriteAsync without binding to a ReadCompleted / WriteCompleted event.
• Resolved an issue where license requests on certain operating systems (Windows 7 or higher) could not be validated.

• Updated ClientAce binaries to address a low-level threading issue that could result in orphaned threads for callbacks.
• Updated the VB .Net examples.
• Added two new C# examples.
• Fixed an installation issue that occurred when the user selected "Yes" in the "Disable Support for this version of Microsoft Visual Studio" prompt during the installation.

• Added Support for Microsoft Visual Studio 2010

• Added Support for Microsoft Visual Studio 2008.
• Added Microsoft Visual Studio 2008 ClientACE components.
• Updated Visual Studio 2003 and 2005 ClientACE components to version V1.1.0.15. This update addresses anomaly with datatype sent by some OPC servers.
• Added 3 Microsoft Visual Studio 2008 examples: Simple and Complex ClientAce VS2008 Examples, plus Simple ClientAce DA_Junction VS2008 Example.
• Separated 3 Visual Studio examples into separate components and install Example only if corresponding Visual Studio is detected. For example, if only Visual Studio 2008 is detected, then only Visual Studio 2008 example will be installed.
• Setup now requires a minimum of Microsoft Visual C# Language installed to Microsoft Visual Studio to enable adding of ClientAce Components to Visual Studio Toolbox.
• Updated the help file for VS2008 and Vista specific requirements.
• Updated the help file for changes in the OPC Items class, the properties are now a list array vs. an object array.
• Update the help file with descriptions of the properties, methods, and events associated with the Server Browser, Item Browser, and DA Junction class objects.
• Updated the help file with example code showing how to use the Server Browser, Item Browser, and DA Junction in a project.
• Updated the License utility with new e-mail address for support rather than sales.
• Updated the License Agreement.
• Fixed issue where using ClientAce objects in forms that are a custom derived class cause them to fail with an exception.
