I have come across something I've never had happen before. I have a ML1000 with RSLogix500 been using for years. The first pic shows Mode G activating when it should & when the Mode G control timer ends, Mode G stays on until timer T4:2 is DN. However T4:2 NEVER gets /DN & Mode G never ends. I have T4:2 holding itself on with the /EN so it should stay on until /DN clears the line.
What I had to do is in the 2nd picture trap the /DN & set a B3 bit to end Mode G, and that works. So why wouldn't T4:2 get /DN on it's own???
EDIT:
Just looked at it & I tried to zoom in, but the pics look a little small, gonna try & post better pics.
