This rung starts messaging each REM Run or RUN mode entry by clearing the EN bit of the first MSG instruction.
Same as above rung.
This rung sets the timeout value. (When using a SLC 5/03 or SLC 5/04 processor
, this rung and rung 2:2 are not
required because you can enter the value 6 into the T imeout value field in the MSG instruction block.)
The MSG instruction energizes upon entry into the REM Run or RUN mode. No input conditions are required.
The MSG instruction is energized when the previous MSG instruction completes.
This rung resets all MSG instructions when the last MSG instruction has completed.
