I would like to be able to detect when the connection between Ignition and the PLC is lost, on the PLC end. So I can notify the operator. What is the best way to do this?

If you’re using our server and drivers then some of the drivers have an “Is Connected” diagnostic tag that might work.

Otherwise I think people will commonly implement some kind of heartbeat mechanism.
