Backup battery (or not)
Controllers are designed to withstand brief power-loss events. A controller may or may not include a backup battery.
The Niagara Edge 10, JACE-8000, andJACE-9000 controllers include integral onboard memory, which preserves runtime data upon a power loss event. By default, these controller platforms do not have backup batteries.
A station running on a JACE-8000 or JACE-9000 has no PowerMonitorService under its PlatformServices container. For continuous operation across power events, an external battery-backed UPS is required to power the controller.
Backup memory support works via a station platform service, the DataRecoveryService. This platform service continuously records all database changes in memory, and upon reboot from a power event, restores these changes.
