Data backup in the event of power failure
Energy reserve (supercap) to support real-time clock (7 days).
Data available if stored to flash memory. Occurs every 5 minutes.
The interval of 5 minutes is only valid for change log but not for trending.
In case of a power failure, trend log data can be lost up to 30 minutes.
