Power Monitor Platform Service (platPower-PowerMonitorPlatformServiceQnx)
This component monitors the primary power status and backup
battery level in many controllers. It applies to legacy platforms
and not JACE-8000 or JACE-9000 controllers.
This PowerMonitorService is found under the PlatformServices container in a station running on many controllers except for those models that are capable and/or enabled for dual battery support. A few configuration properties allow you to change the shutdown delay time, as well as alarm source configuration for both types of alarms (low battery level, primary power lost). Typically, support is enabled and configured at controller commissioning time.
An SRAM-equipped controller can be configured
for battery-less operation (the platDataRecovery module
must be installed, and the controller licensed for the dataRecovery
feature). The PowerMonitorService continues to
monitor for an (optional) backup battery, and upon loss of AC power
allows continuous operation on battery power until the Shutdown
Delay time is reached. This happens unless you set the Battery Present property (of controller’s PlatformServiceContainer) from true (the default) to false. This disables backup battery support and, when there is no backup
battery, prevents ongoing battery bad nuisance alarms.
| Property | Value | Description |
|---|---|---|
| Primary Power Present | true or false | Reports if the controller is being powered by AC power (true) or not (false). |
| Battery Good | true or false | Reports if the last controller test of the NiMH backup-battery was good (true) or not (false). |
| Time of Last Test | timestamp | Reports when the battery was tested last. |
