1.5 Backup Data

1.5.1 Data Backup

Data includes the Program, Comment, File Register (D1000 ~ D2499), and parameter data.

This will be stored as long as the EEPROM is not damaged. Mitsubishi Electric has

guaranteed a life cycle time of 10,000 writes to the EEPROM memory. Users may experience

operational writes to the EEPROM in excess of 10,000; however, due to temperature effects a

quantitative estimation cannot be given.

If the PLC has been powered ON for five minutes or more, the following device data will be

saved in the EEPROM at power-down:

S0~S127, M384 ~ M511, C16 ~ C31, C235 ~ C255 and D128 ~ D255.

If the PLC is powered ON for less than 5 minutes, the above data is not saved!

1.5.2 Capacitor backup

Only the RTC is backed up by the capacitor.

The capacitor backed memory will retain data for 10 days (Ambient temperature: 25ºC). The

capacitor requires 30 minutes to recharge upon power-up. There is no internal hardware reset

function, thus, after a 10day duration the RTC data may be unfixed and not reset to 0.
