Schneider Advantanys PLC Communitcating

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

what is the make and model of the PLC that has the logic and what is the make and model of the PLC that has the spare output?
