Battery-less controllers

The Niagara Edge 10, JACE-8000, JACE-3E and JACE-6E controllers include integral onboard SRAM, which preserves runtime data upon a power loss. By default, these controller platforms do not have batteries. An SRAM option card is also available for any JACE-6 and JACE-7 series controller. These controllers can operate without any backup battery, onboard NiMH or otherwise.

SRAM support works via a station platform service, the DataRecoveryService. This platform service continuously records all database changes in SRAM, and upon reboot from a power event, restores (plays back) these changes.

Except for the JACE-8000 controller, any SRAM-equipped JACE controller can also have a backup battery, and be configured to use either SRAM or backup battery, or both. By default, its station’s PlatformServices contains both the PowerMonitorService and the DataRecoveryService.
