I have more experience with FANUC robots but our latest project is an ABB robot. Communication between our PLC and the robot is set up and working correctly and now I need to set up a program to monitor this connection. With a FANUC setup I could simply assign an output to the "heartbeat" option and the PLC just needs to monitor that output. ABB does not have this capability as far as I can tell and we also do not have the multitasking option to allow me to set up a background program. What would be the best way to set up something similar to the FANUC heartbeat with ABB software? Or is adding the multitasking option really my only option?

Make a cross connection from a PLC input. The robot output can echo that input, but the PLC will have to pulse it on and off.

That is a good idea I will look into but I found, as I was digging, an option under operators safety that says heartbeat. I changed it from false to true but that's the only option it gave me. Would this work for what I'm trying to accomplish and if so how do I set it up?

I am not familiar with that.

(Configuration - I/O - Signal)Create Output signal with Invert parameter.
(Configuration - I/O - Signal)
Create Input signal
(Configuration - I/O - Cross Connection)
that's all.
PLC Signal On -> Robot Output OffPLC Signal Off -> Robot Output On
PLC can get status monitoring.
