Well outputs do not get simulated, so saying that unsimulate all does not make sense.Did you check the background logic? Maybe someone has something in there.
All outputs as in everyone? Or just ones in that program?
Maybe you could do a backup and send to me? I would be willing to look at it and see what I see.
Yes, typically don't simulate outputs but the option is still there. I did check the bg logic. Nothing there. Yes, everything configured on rack 89, slot 1, 1-64 (Ethernet/ip) goes to simulated state when a program is running. I also do not have any other DIO's assigned besides the Ethernet/ip.
