power loss and auto reset SLC 503

Is there a way to set up an auto reset on the SLC 503 processor
to clear the power loss detection rather than using the keyswitch to clear the error? I realize the alarm is stored in the S registers. could using the S1/15 input for the first cycle detection be used to clear that fault?

Go to the Process Status File, Errors tab and Set S:1/8 to 1, then save and download. This should force the controller to clear any Major/Minor faults that happened when power was lost and put the CPU in REM Run on power-up. I believe the keyswitch has to stay in REM for this to work.
