I was curious about how some of you guys handle simple motor logic. I've been doing this for some time now but would like to hear your opinions. To keep this post managable lets start with this criteria:
Motor : Single Speed, FWD/REV
Operator inerface : FWD, REV, Stop, Tag Out, Clear Tag Out
Inputs : FWD AUX and REV AUX
Outputs: FWD and REV (Both maintained)
Permissives: 1 per direction
General Alarms : Fail to Start FWD and REV, Fail to Stop FWD and REV; Congruency Alarm (both feedback true).
These are my usual alarms, please let me know any others that you use. I've seen plenty of "Standard Logics", but I'm convinced that all of them can be improved.
If this is too basic, we can try servos, but I'd like to start simple.
Thanks,
Steve
