2.4.1 Memory Backup Function
The FP0R-T32 control unit has a secondary battery (Charging type).
The backup function for the operation memory and clock/calendar function can be used.
Backup of operation memory
(1) Timer/Counter (T/C)
(2) Internal relays (R)
(3) Data Registers (DT)
(4) Step ladders
The range specified with a programming tool is the hold area to be backed up.
If the range is not specified, it will be the area of the default.
Note) If the battery is out of charge and the hold area becomes indefinite, the value in the hold area will
be cleared to 0 when the power supply is turned on again.
Key Point:
Programs and system registers will be held in the internal ROM regardless of the built-in back up battery.
