Hold-type memory ranges (without battery)

The PLC keeps the values of hold-type memory areas without battery. The address range of hold-type memory areas is dependent on the PLC type.

NOTE

FP0H, FP-XH, FP-X, FPS (compact PLCs with an optional battery):

If you mount a battery, the whole data memory (adjustable) can be used as a hold-type memory.
If you do not mount a battery, the data memory area specified in the columns under "Hold-type memory area (without battery)" in the table above can be used as a hold-type memory.
Without battery, the whole data memory has a limited holding power, which lasts for about 60 seconds (valid for an FP0H PLC). After this time, all memory areas apart from the standard hold-type memory are initialized to value 0.

FP0 T32CP and FP0R T32CP:

A maintenance-free, built-in supercap accumulator is used to hold the whole data memory (adjustable).
The backup time ranges from 14 to 50 days and depends on the ambient temperature.
The typical service life of the accumulator is up to 10 years at an ambient temperature of 25°C.
When the accumulator is empty, the PLC initializes the memory to value 0.
The data memory area specified in the columns under "Hold-type memory area (without battery)" in the table above can be used as a hold-type memory even if the accumulator is empty.

FP0R F32CP: Data registers of 32765 words can be written to the built-in F-ROM, which serves as a hold-type memory area.

FP7:

If you do not mount a battery, the data memory area specified in the columns under "Hold-type memory area (without battery)" in the table above can be used as a hold-type memory.
Project data (program and PLC configuration) and operation memory (except for clock/calendar data) are automatically backed up by the built-in non-volatile memory (Flash-ROM).
The clock/calendar function keeps working for about one week thanks to the built-in capacitor even if no battery is used. In order to charge the built-in capacitor, supply power to the CPU unit for at least 30 minutes.
