Performance Specifications
*1 Interrupt from the intelligent function module and high-speed pulse input/output module.
*2 The value listed above indicates the number of files stored in the root folder.
*3 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

). 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.
*4 It is possible to back up all devices in device (high-speed) area. When a battery is used, it is also possible to back up devices in device
(standard) area.
