Create your own OPC DA Servers using the OPC DA .NET Server development Toolkit (DANSrv).
The OPC DA .NET Server Toolkit (DANSrv) has an OPC DA V2.05 and V3.0 compliant generic server and a .NET customization assembly.
No COM programming is required. The server customization for a particular application is done in the .NET customization assembly. Many VB.NET and C# samples are provided. Custom applications can be based on these sample applications or be wizard created. The wizard GUI offers choices for the needed customization functions and creates sample code for the selected features.
The DANSrv server toolkit is well suited to quickly implement simple servers or create high performance OPC servers with ten thousands of items.
The .NET customization assembly interface defines a number of methods that are called from the generic server and a number of callback methods, allowing the customization assembly to call methods in the generic server, such as writing a new item value into the cache.
