I am trying to use the OPCDA Client tool to broswe the OPC server on PC running the Siemens WinCC Flexible Runtime application. It has been configured to make all the tags in the application available to the OPC Server. I have configued DCOM on the local PC as well but still and not able to see the OPC Servers using the OPC Client Tool (installed on our PI Interface Server(s)). I spoke with Siemens and they told me that the application needs to be running which it is but still I am getting no luck. Anyone out there in the PI wolrd run into this same issue? Any help/insight would be greatly appreciated.
