Hi all. New to the forum.
I am looking for some information on how to get two PLC's to communicate with each other and get information from one plc to fire a physical output from a separate PLC and plc program located elsewhere.
I have a few override functions on a conveyor hmi that requires a warning light putting in to show if any of them are on. I have found where it is written in the plc and have wrote the code to fire one single output when any of the overrides are on. The only problem I have is the spare output and output card I have is on a different PLC. Not for the conveyor but for robots. Now they talk between each other constantly but how do I write the logic to fire the spare output on the output card on a different PLC Rack?
Any help would be very much appreciated
Thanks in advance
Tom
