Hi there, apparently when a subroutine is suddenly no longer being called up in your program scan, the energized outputs in the subroutine will stay on.
In my case these outputs are valves. Not good!
Is it possible to eliminate this problem (have the outputs de-energize) by using bits for each physical output vs. direct outputs ? I would then place in the main ladder the needed rungs where if the bit is ON then it will energize the output (valve).
Or will bits stay on as well?
