I am writing an alarm message to the lcd with the folloing logic;
2 logically OR'd N.C. contacts to 10 sec. (TIM)
coil, once timed out N.O. t contact sets {Cufn}
Cufn = SETLCD 1,2, "PUMP_FAULT"
The logic works correctly, the message prints to the
lcd simulator if either conact is closed and the timer
has expired; my question is how to clear the message
if the faults have cleared.
cheers
