só in that case as devil said, you need to have concurrent job and use the pstart (paralel start) of the programs. Once you make New program you set the robot you want to use and if you need different controlle groups you need to define them. Like 2 robots and a base or external axis.
But basically you write the program for the robot you want to use, with defined control group for that certain robot, and start it with pstart.
Very thanks for your support!
