Should Reset Range override off-delay timer?
« on: February 28, 2023, 05:42:32 PM »
 I have a program where the first rung in Main is an e-stop button input that resets the full range of relay outputs (Y0-Y31). I noticed today that this rung is not resetting a relay output that is being held in by an off-delay timer. Is this normal?

Last one wins. Stick your estop in the bottom of scan task.

Can I use the $BottomofScan to override a PID loop that is in auto, by writing directly to the analog register? (RY0)

That should work.
