Power failure retention
(Clock data
Û2
)
Retention method Large-capacity capacitor
Retention time 10 days (Ambient temperature: 25°C (77°F))
Power failure retention (Device) Capacity for power failure retention 12 K words maximum
Û3
Û
1: The value listed above indicates the number of les stored in the root folder.
Û
2: Clock data is retained using the power accumulated in a large-capacity capacitor incorporated into the PLC. When voltage of the large-capacity capacitor drops, clock data is no
longer accurately retained. The retention period of a fully charged capacitor (electricity is conducted across the PLC for at least 30 minutes) is 10 days (ambient temperature: 25°C
(77°F)). How long the capacitor can hold the data depends on the operating ambient temperature. When the operating ambient temperature is high, the holding period is short.
Û
3: All devices in the (high-speed) device area can be held against power failure. Devices in the (standard) device area can be held also when the optional battery is mounted.
