JACE power monitoring

By default, through the PowerMonitorService, any JACE provides status monitoring of the following items, via “Boolean” type slots:

AC power
(“Primary Power Present” slot) — True whenever AC power is currently supplied to the JACE.
Battery level
(“Battery Good” slot) — True if last JACE test of NiMH backup-battery was good.

Also included is a “Time of Last Test” slot that provides a timestamp for the last battery test.

If needed, you can make Px bindings or links to these slots (however, see “PlatformServices binding and link caveats”).

In addition to these read-only status slots, the PowerMonitorService provides related configuration slots, which you typically review at commissioning time. For more details and a related procedure, see “JACE power monitoring configuration” in the JACE Niagara 4 Install & Startup Guide.
