Regarding the use of sub-routines in VisiLogic to model states machine....
I have a idea of making use of sub-routines to model a state machine since the sub-routines can be make to only be called when its inputs ladders condition is true.
But to do that, I need to fully understand how a relay that got energized within a sub-routine will behave after the calling of that sub-routine is isolated.
To further explain my question, I will create a scenarios of a simple ladder program here.
Let say we have Input 1, Sub-routine "Sub1", Relay 1, Timer (Delay) 1, Output 1. Se
It was easier to write a state machine example program than to try to go all verbose and explain visual concepts with words. I also want to add an addendum to my state machine calling criteria - often you can just call the state machine all the time and just let it "idle". You don't really gain anything in scan time for simple sequences and then you don't have to worry about leaving anything on because the subroutine isn't being called. This is the best path to take if you haven't done one be
