Evaluating via the diagnostics buffer
When they are issued, the following messages are entered once in the diagnostics buffer:
Table 2- 4 Messages of the diagnostics buffer
Entry Meaning Remedy
Non-volatile data loaded from file
(Persistent Data File Loading done) Non-volatile SIMOTION data has been
successfully restored from the backup
file on the CompactFlash Card.
-
Non-volatile data loaded from the backup file
(Persistent Data Backup File Loading done) Non-volatile SIMOTION data has been
successfully restored from the backup
copy of the backup file on the
CompactFlash Card.
-
Error while loading non-volatile data from a
file
(Persistent Data File Loading Failure)
Backup file or backup copy could not be
loaded.
Possible causes:
•
Backup file or backup copy not
available
• Invalid data in backup file
Use the
_savePersistentMemoryData
system function to generate a
backup file with valid contents.
Refer to the
SIMOTION SCOUT Configuration Manual for information about how to read out
the contents of the diagnostic buffer.
Evaluating via system variables
The system variables in the device.persistentDataPowerMonitoring structure indicate the
state of the non-volatile SIMOTION data.
Table 2- 5 Status of the non-volatile SIMOTION data
System variable Designation Status Updating
rtcFailure
(as of V4.3)
Indicates that the clock
contents (RTC) are invalid
(clock must be set again)
NO (91)
YES (173)
The status is updated once during power-up;
the status must be reset to "NO" via the
application; the status is retained even after
power off/on.
retainDataFailure
(as of V4.3)
Indicates a checksum error of
the non-volatile SIMOTION
data; can be an indication of
defective HW
NO (91)
YES (173)
The status is updated once during power-up;
the status must be reset to "NO" via the
application; the status is retained even after
power off/on.
persistentDataState Reading the persistent data See the table
below
The status is updated during power-up.
As of SIMOTION V4.3, a data loss of the real-time clock is signaled via the system variable
device.persistentDataPowerMonitoring.rtcFailure = YES.
The system variable device.persistentDataPowerMonitoring.persistentDataState indicates
the state of the non-volatile SIMOTION data after powering up:
