3.6 UPS functionality
In case of supply voltage failure, the UPS functionality (uninterrupted current supply) of
the device provides a backup function for saving the user data (retain variables, logbook
data) before the device will be switched off.
In order to minimise the power consumption and increase the safety during the buffer
times, circuitry parts that are not required can optionally be switched off during a supply
voltage failure (e.g. supply of the backplane bus, supply of the devices connected to the
USB ports).

3.7 "Real Time Clock" functionality
The operating system contains the CMOS−RTC time via a maintenance−free chip.
The CMOS−RTC time is internally saved for a minimum period of 14 days. Then the time
must be set again manually via the »WebConfig« (parameter 91).
A battery is not
required.
