OK, I had a chance to connect to a real PLC and use real world PLC program.
This time everything was pretty much straightforward like described in the video and indeed there is a S7_connection shown in the OPCScout.
OPC server is running normally, but variables are read with quality code "invalid", which means OPCscout doesn't read the variables.
I have made a test with Test variable.
Now, partial success is achieved, but the next step is to troubleshoot this further, trying to see why Quality is invalid. I have tried with cycle time in OPC 1000 ms instead of default 100 ms, but that didn't solve the problem.
PLC time is OK even though it is shown wrong in teh OPC scout.
