Within the configuration of a SmartStruxure Lite MPM CFG1 object, there is a "Save Period". What is this, and what is saved?

Issue

What files are saved, to where and why is this used.

Environment

MPM-VA

MPM-UN

MPM-GW

Cause

The running database of a SmartStruxure Lite MPM controller is in the controllers volatile memory (RAM), in order for this data to be preserved during a power failure or reboot this needs to be saved to non volatile memory (Flash)

Resolution

The save period is for backing up the controller database to flash memory, this can be set to Never, Hourly or Daily. All programming and runtime information is then saved to the controllers flash memory so that it is not lost during a power failure or controller reset.

Stored data includes Controller status, configuration changes, updates such as trended information or setpoint changes, and Lua scripts.
