To review/adjust PlatformServices properties for the JACE

With a station in the JACE running, and that station opened in Workbench, do the following:

1. In the Nav tree, double-click Services and then PlatformServices.

   Its “Platform Service Container Plugin” displays in the view pane, as shown in Figure 27.

   Some properties are read-only status types, similar to many seen in the Platform Adminstration view. Other configuration properties are available. A group of 3 config properties allow adjustment of the time, date, and time zone settings for the host JACE (alternately accessible using a platform connection to the JACE). Access to these properties is useful if the installation requires all setup access using a browser only.

2. Scroll down to the “Battery Present” property.

   
   
   

   By default, the Battery Present property is true. This is the proper setting for any JACE controller, unless:

   • It is SRAM-equipped, and has no backup battery installed (NiMH and/or external 12V), and:

   • It has the DataRecoveryService running and enabled (license includes a dataRecovery feature).

   In this case only, set the “Battery Present” value to false and click Save. After the next reboot (required), this prevents “battery bad” nuisance alarms from re-occurring.

3. As needed, review other platform service configuration properties, which include the following:

   It is strongly recommended that you leave the following properties at default values, unless otherwise directed by Systems Engineering.

   • Locale — Determines locale-specific behavior such as date and time formatting, and also which lexicons are used. A string entered must use the form: language [“_” country [“_” variant]]

     For example U.S. English is “en_US” and traditional Spanish would be “es_ES_Traditional”.

     See Oracle documentation at http://docs.oracle.com/javase/1.4.2/docs/api/java/util/Locale.html for related details.

   • Engine Watchdog Policy — Defines response taken by the platform daemon if it detects a station engine watchdog timeout. With the watchdog, the station periodically reports to the platform daemon its updated engine cycle count. The watchdog purpose is to detect and deal with a “hung” or “stalled” station, and is automatically enabled when the station starts.

     Watchdog policy selections include:

     • Log Only — Generates stack dump and logs an error message in the system log.

     • Terminate — (Default) Kills the VM process. If “restart on failure” is enabled for the station (typical), the station is restarted.

     • Reboot — Automatically reboots the host JACE platform. If “auto-start” is enabled for the station, the station is restarted after the system reboots.

   • Engine Watchdog Timeout — Default is 1 minute, and range is from 0 ms to infinity.

     If the station’s engine cycle count stops changing and/or the station does not report a cycle count to the platform daemon within this defined period, the platform daemon causes the VM to generate a stack dump for diagnostic purposes, then takes the action defined by the Engine Watchdog Policy.

   • Engine Station Auto-Save — Either Enable (default) or Disable.

     Allows for “auto save” of running station to “config_backup_<YYMMDD>_<HHMM>.bog” file at the frequency defined in next property. Auto-saved backup files are kept under that station’s folder.

   • Station Auto-Save Frequency — Default is every 24 hours for any embedded JACE, range is from 1 to many hours.

   • Station Auto-Save Versions to Keep — Default is 0. Oldest of kept backups is replaced upon next manual save or auto-save backup, once the specified limit is reached. Significant flash space is saved by keeping this 0 or perhaps 1.

   • RAM Disk Size — In MB, where default is 16 for a JACE-4/5 series, 8 for a JACE-2 series, 32 for a JACE-3E or JACE-6 or JACE-6E series, or 48 for a JACE-7 series. Specifies size of RAM disk used to store history and alarm files.

   For further details on these and other PlatformServices properties, refer to the “PlatformServiceContainer parameters” section in the Platform Guide.
