Version Info

The OPC AE .NET Server Toolkit is an Alarm & Events Add-in for the DANSrv OPC DA .Net Server Toolkit, making the server compliant with the OPC specifications DA2, DA3 and AE. Event Sources can be OPC DA items or any othe signal source. The toolkit is flexible and does not restrict the user. All application specific server code is in a .NET assembly that can be coded in C#, VB.NET or with any .NET compiler. The generic server handles the .NET wrapping of client calls and callbacks. The user can implement a simple interface with convenient .Net data types. The AE option is available for the DANSrv Standared Edition and Professional Edition, making the toolkit economical for simple applications and powerful enough for highly complex applications.   Why use .NET for OPC Servers ? .NET is widely used for desktop and web service applications. VB.Net and C# have great advantages and are the preferred tools of many software developers. DANSrv Toolkit based OPC server development is not much different from desktop applications development. No DCOM issues have to be handled. The OPC server can interface a database or e.g. use TCP/IP to communicate with a device. The database access or the TCP/IP communication is what has to be implemented in the customization assembly and this is well supported by .NET. Serial device communication or direct I/O port access can alse easily be handled with .Net. Serial I/O and Port I/O classes are provided and even more sophisticated implementations of such classes are available as software component products from multiple vendors.

The features of the OPC AE server toolkit include: OPC AE V1.1 compliant generic server and sample applications High performance and efficiency in large and small applications Free-threaded design and hand-optimized .Net wrappers Fully integrated into Visual Studio .NET. Generic server supplied for: .NET Framework 1.1 in 32-bit mode .NET Framework 2.0 in 32-bit mode .NET Framework 2.0 in 64-bit mode The same customization plug-in assembly works with all generic server versions. VB and C# sample application projects for Visual Studio 2003, 2005 and 2008.  The Visual Studio integrated help contains detailed information about the customization interface and includes the OPC specifications. Context sensitive help displays the needed information without long searches. The customization assembly can easily be debugged The supplied test clients allow the user to interactively test each OPC server function Developer license with one time fee, no run-time licenses required The license includes an Updates/Support subscription for 90 days.

Sample Servers

Fully functional and OPC compliance tested VB.NET and C# sample applications are provided. and can be used as the starting point for user specific Alarm&Event servers.

Test Client

The provided Alarme&Events test client can be used to check the server functionality. The server capabilities can be queried and filters can be set to restrict the reported events.
