Precautions for Safe Use
Do not turn OFF the power supply to the PLC when the BKUP indicator is lit. It indicates that
data is being written to the backup memory (built-in EEPROM).
If the power supply is turned OFF while the BKUP indicator is ON, data in the backup memory
(built-in EEPROM) may be destroyed.
