States Description
fanbattery of data type StructDeviceFanBattery (the system variables are of the data type EnumFanBattery)
.batterynecessary MANDATORY Battery is required for the backup of the non-volatile data and the real-time clock
(RTC) of the device. .batteryexisting can
be used to query whether a battery is
installed.
OPTIONAL The non-volatile data and the real-time clock (RTC) are backed up via Super‐
Cap.
A battery can be used as an option to extend the backup time. .batteryex‐
isting can be used to query whether a battery is installed.
Example: D4x5
OPTIONAL_RTC
1)
A battery is not required for backing up the non-volatile data.
Only the real-time clock (RTC) is backed up via SuperCap. A battery can be
used as an option to extend the backup time of the real-time clock. .batteryex‐
isting can be used to query whether a battery is installed.
Example: D4x5‑2
NOT_MANDATORY
1)
