Hello, I'm new here and new to AB programming. I come from the land of DeltaV
I have a CompactLogix 1769-L1, and found out how to programatically reset fault code 01, and type 01 after a power failure by reading the AB manual. I did this with a ladder routine and GSV/SSV instructions like they show in the manual. I added another routine to the Power-Up Handler that is an SFC, and have the ladder JSR to the SFC after the power-up fault is reset. My problem is the SFC starts and the first step completes, but it won't transition to the next step (even if I try and force the transition.) Do you know if the routines in the Power-Up Handler only execute for a single scan, or something like that? When do Power-Up Handler routines stop executing? It looks like both the ladder and SFC are active when I go online because they have green borders around them.
