1.2 Backup Function
This function saves property values and data set with configuration functions in a BACnet module automatically when a
programmable controller system is powered OFF.
Data is saved in the internal memory. The saved data is held even after the power is OFF.
When powering ON, data is automatically restored from the internal memory.
Even if a power discontinuity occurred due to a power failure, the system can be restarted immediately after a recovery.
The time available for backups is limitless.
After recovering from a power interruption, the property values and data set using configuration functions (BACnet request function, BACnet monitoring
function, COV interaction function, Event interaction function, network information, basic information, etc.) are restored from an internal memory to buffer
memory.
