We are starting to look at using the OPC UA Connector to talk to some new S7 PLC's we've purchased. I have started messing with the connector, but even after reading the manual front-to-back, I am not having any luck actually connecting to the PLC.
We're able to use Siemens software to do it, so I know it's running and the OPC server is active. However, the Siemens client is just using a URL like this: opc.tcp://<ip address>:4840 with nothing after it (like /OpcUa/SimulationServer or similar).
So, when I put that into the connector config and click "Discover Available Endpoints," it repopulates with:
None of those options mean anything to me, and anyway, none of them work. If I try to click the "Export Available Type Definitions" button, I just get a 501 error (Cannot connect to server).
Is anyone using this, and if so, what URL do you use? I also am not aware of a user name or password. Again, when using the Siemens client, it just works.
