CAUTION
• The dedicated input ON/OFF process from the master station PLC to the
controller must be carried out at an interval of 100ms or more. If the interval is
too short, the dedicated input may not be recognized. (This also applies to the
same dedicated input and differing dedicated input intervals.)
• If dedicated outputs are provided for the dedicated inputs from the master
station PLC to controller, use them.
