How to transfer data from Siemens WinCC OPC Server to 800xA system
Our customer have a Siemens process system that based on WinCC platform, now they want to connect this Simens system to a 800xA 5.1 system for energy management. The Siemens WinCC OPC Server is available and installed on Siemens system's computer.
So I want to connect and transfer data from Siemens WinCC's OPC Server to 800xA's OPC Client.
My question: If I need to install any software or buy any ABB's license to do this work?
I failure in trying to connect 2 system through DCOM. Can somebody help me?

For integrating 3party OPC Servers into 800xA refer to 3BDS011222-510 (System Configuration) Capter "Integrating OPC Servers into 800xA". There you find also DCOM settings. You don't need a special 800xA license.
DCOM can be tricky, especially if you are in different domains. And even with correct DCOM communication I had problem with the automatically reconnect after a brocken communication path.
I would recommend to use a tunneler software to avoid all these DCOM problems.
If you are going to transfer the data from wincc OPC server to 800xA OPC client?
This you can achieve thorugh the generic OPC it doesnot require any license.
If you make wincc has OPC client to communicate with system 800xA OPC server it needs once license per opc client.
