The system job is always running in back of robot, if the IN#(1) = OFF the system give alarm.
For use system job, go to JOB Menu and select CREATE NEW JOB and see in JOB TYPE are there SYSTEM JOB or not. if there are you can create a new job with SYSTEM JOB type and write your codes on it.
My choices are "ROBOT JOB" or "CONCURRENT JOB". Might that be the same thing? I'm looking thru my manuals but have not found an explanation yet.
