To test, I am setting up a connection in "Emulation Properties". Browsing for server does not work, but I know the server name ("RSLinx OPC Server") with this connection in the "Connections" tab. I have checked "Active" in the Connections tab.
I am able to add a Sensor or Control and browse to see all tags on the (Rockwell) PLC, indicating it is correctly connected to some extent.
However, I do not see the value of the tags when running the study, and writing changes in FlexSim does not change the values of the PLC tag(s). When pointing a Variable in the process flow to the tag, I see the variable value when NOT running the simulation ("View Variable..."), but the viewer goes blank when the simulation is run:
If I check "Subscribe to Changes", then I always see "0", regardless of running/not-running the simulation, and regardless of the actual value in the PLC.
What further do I need to make OPC read/write of tags work correctly?
(FlexSim is currently 18.1.1)
Thanks!
