@ Brendan, say on rung 1 when from the HMI the momentary PB is pressed it turns on the PB_Run_HMI bit then in the same rung another bit PB_Run is turned on and also the PB_Run_HMI is unlatched. Mind you the PB_Run is going to be on up until the next scan that it will go off, but before that first scan is over that PB_Run bit will latch on the LT_Run bit so on the next scan when the PB_Run goes off the LT_Run is on
So i also modified the routine such that i got rid of rungs 123 and just directly linked the HMI momentary pb's to the PB_run, PB_Standby etc with having any unlatch bit for them, because technically the momentary pb unlatches itself, and still the issue is still present
after that didn't work i add the unlatch bits for PB_Run, PB_Standby, and PB_Off at the end of the routine and still the same issue.
