Hey folks. I created a routine in the power up handler folder in the controller in a 1769-L30ER. I wanted to have the controller go through a start sequence after a POWER LOSS. That is, controller has lost incoming power.
When I downloaded the program with that additional change plus others, the controller faulted, something to do with the power up routine. I cleared the fault and it runs fine.
Was this just because I DIDN'T lose power, so to speak, just did a download? In other words, is this normal?
The power up routine is it's own routine with it's own program tags. A-B said not to assign the routine in a task. There are, however, a couple of bits that are in the main task such as alarm reset and start.
Any help is always appreciated and thanks in advance. (I'm not sure how to include the logic on this post)
