Description
The SET instruction executes when the trigger is turned on. Output turns on and holds on even if the trigger’s
state changes.
The RST instruction executes when the trigger is turned on. Output coil turns off and stays off even if the
trigger’s state changes.
You can use relays with the same number as many times as you like with the SET and RST instructions.
(Even if a total check is run, this is not handled as a syntax error.)
