Re-starting program using UOP

I wonder if the abort is aborting your action program.

You should try doing this in BG Logic instead so it isn't affected by the CSTOPI signal. You can't use wait commands in BG Logic so instead you have to count scans. There are threads discussing that on the forum.

You can't toggle CSTOPI during program execution. It needs to be done when main program is paused. The way you want to toggle your CSTOPI depends on you, from PLC, from push button, from BG Logic using internal stuff.
