•
Bits in the Holding Area can be force-set and force-reset.
•
When a self-maintaining bit is programmed with a Holding Area bit, the self-maintaining bit will not be
cleared even when the power is reset.
•
If a Holding Area bit is not used for the self-maintaining bit, the bit will be turned OFF and the self-
maintaining bit will be cleared when the power is reset.
•
If a Holding Area bit is used but not programmed as a self-maintaining bit, the bit will be turned OFF
by execution condition A when the power is reset.
Precautions for Correct Use
Precautions for Correct Use
•
When a Holding Area bit is used in a KEEP instruction, never use a normally closed condition
for the reset input.
When the power supply goes OFF or is temporarily interrupted, the input will go OFF before
the PLCs internal power supply and the Holding Area bit will be reset.
