Defaults to true, to enable SRAM support via this service. For the JACE with onboard SRAM (e.g. JACE-6E or JACE-3E), you can set this to false to disable SRAM support—in which case it relies on its installed backup battery and its PowerMonitorService to preserve station data upon loss of power. (If an SRAM option card-equipped JACE, you can simply remove the SRAM option card and uninstall the platDataRecovery software module).

The current status of the DataRecoveryService, which is typically “Ready”. Other states include “Starting”, “Configuring”, “Replaying”, “Saving”, “Stopping”, “Stopped”, “Fault” and “Unknown”.

Reflects the last time a station save occurred (config.bog written to flash memory). This save may (or may not) have occurred as a result of the DataRecoveryService.

Boolean that reflects if last station save attempt was successful, as either “true” or “false”. This save may (or may not) have occurred as a result of the DataRecoveryService.

Note in the case of a newly-created DataRecoveryService, this is “false” until the next save occurs.

Configurable in N4.0 and later. Number of station saves that are allowed to occur during the Station Save Limit Period before it is determined that the station is spending too much time saving. Exceeding the limit throws the Data Recovery Service into fault since too much data is being generated.

Configurable in N4.0 and later. The period of time for Station Save Limit. If enough saves occur during Station Save Limit Period to exceed the Station Save Limit then the service goes into fault. For example, more than 5 station saves in 3 minutes period triggers a fault.

Reflects the total size of all the “flushed to flash” data block files (“.drdb” files) that exist in the station’s /dataRecovery folder, in KB. Initially, this will be 0, until the first SRAM block flushes to flash. It will then increment by that KB amount for each subsequent SRAM block flushed.

Note this value is continually compared to the “Persistent Capacity” property in the Blocks Configuration property section.

Configurable in N4.0 and later. Boolean (true/false) value, generates an alert (low priority alarm type) that will indicate that a Data Recovery Replay (power was lost) occurred. This is a persistent artifact that will show up in the alarm console, since it can be useful to know when power loss occurred.

Default is false. If set to true, upon any controller boot sequence in which SRAM recorded data is discovered and played back, a corresponding alert is routed to the Alarm Class named in the Data Recovery Alarm Support container. The following figure shows details for such an example alert.

Configurable in N4.0 and later. This is the standard container slot for routing platform service-generated alarms or alerts, in this case an alert from the DataRecoveryService upon any controller boot sequence in which SRAM recorded data is discovered and played back. These properties work in the same fashion as those in an alarm extension for any control point.
