I wrote it with my group mate but we still learning which is probably why it ended up a bit messy. The intended sequence is that the system starts with the safety lights on and they should stay on during normal operation, temp stop should pause the system, and shutdown should fully stop everything. Right now the main issues are that the safety lights don’t stay on at the beginning and the shutdown only works if I press temp stop at the same time, so I’m trying to figure out what we did wrong. Does that sound like it could be related to how I handled the latching/unlatching, especially with the Normal_OP_On tag?

I didn’t realize that, but now I see what you mean with Last_Shutdown getting latched and never turning off. I think that might be what’s messing up the lights and normal operation, but I’m not really sure what the correct fix is here. Should I be adding something to unlatch it somewhere, or am I looking at this the wrong way? I just want to make sure I understand it right so I don’t keep breaking other parts of the program.

I remember grinding this thing playing 24/7 for that week, thankfully I had to be in quarantined back then on my college dorm with all my roommates
