The JACE-NXS provides “system monitoring” (sysmon) of internal temperatures of its CPU and main printed circuit board. These values can be indicators of the physical “health” of the device. Each temperature has a high alarm limit, used for offnormal alarming. Using Workbench, you can modify these limits and related parameters in a running station on the JACE, by accessing its HardwareMonitorService (under the station’s PlatformServices container).
To configure hardware system monitoring for the JACE-NXS
With a station in the JACE-NXS running, and that station opened in Workbench, do the following:
-
In the Nav tree, click to expand the station’s Services, PlatformServices, containers to reveal all contained services.
-
Double-click the HardwareMonitorService.
Its property sheet displays in the view pane, as shown in Figure 30.
Two of the slots are read-only status monitoring properties, using a “float” datatype, as follows:
-
Cpu Temp — Temperature of main board below the CPU.
-
Board Temp — Temperature from sensor mounted elsewhere on the PC board. This provides a more general state of the environmental conditions inside the JACE-NXS.
If needed, you can link either of these properties into station database logic or Px graphics.

As needed, change configuration properties stored in the JACE-NXS platform, which include:
-
Sysmon Poll Rate
Defines the interval between system measurements. In normal operation, alarms are not generated or reset any faster than this. The default value is every 15 seconds.
-
CPU Temp Hi
High limit for CPU temperature, above which an alarm occurs.
-
Board Temp Hi
High limit for PC board temperature, above which an alarm occurs.
-
CPU Temperature Alarm Support, Board Temperature Alarm Support
Each is a container for properties that define how the different “platSysmonNxs” alarms are handled in the station, including the alarm class to use and other “alarm source info” type parameters.
