Detect Lost connection to Gateway

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?

I need this also, have you found a way to detect when a device loses connection?

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.
