I am trying to figure out how to make a connection status process that continually checks to see if the plc is connected to the ignition server. I would like for a plc variable to change states based on connection status. The issue I am running into is that once the ethernet cable is unplugged from the PLC, I cannot change the state of that variable from ignition since there is no coms. I simply just need a state change to take place on a variable in the PLC when connection from the plc to the ignition server changes.
Is there a connection status system tag I can target on the ignition that will write to the plc when the connection is defective?
