You can use two logically AND'd N.O. contacts to drive another differentiated custom function with the line "SETLCD 1,1," ". So when both the contacts are closed the message is erased.
: 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
