How to develop OPC Servers with .NET ?

Advosol offers toolkits and components that support the development of OPC DA servers and XML DA web services. The application specific server part can be developed as a .Net assembly using Visual Basic .Net or C#. All COM Interop respecively web services handling is done in the generic server. The same customization plug-in assembly can be used with the DANSrv OPC DA server and the XDARap XML DA web service and the XiPLUS OPC Xi Server. The same customization plug-in assembly can be used with the server running in 32-bit or 64-bit mode. Access to a mix of OPC DA and XML DA servers is further supported by gateways. The characteristics of OPC DA / XML DA servers and gateways is outlined below:

OPC DA, XML DA and OPC Xi servers with the same customization plug-in

Having a native solution for either COM based OPC DA or web service based OPC DA or web service based XML DA simplifies usage and configuration and offers best performance. However only one type, either OPC DA or XML DA can be installed.

The COM server doesn't need any web service features and the Xi and XML DA servers are native web services, not using any COM features. The rather complex Windows security configuration is minimized and each server is performance optimized for it's environment.

The same plug-in .NET assembly can be used with the different servers. The plug-in interface is indepent from the client communication.
With a single server development effort you get native servers for differetn OPC specifications. The need for converter servers is minimized.
