Power-up and non-volatile SIMOTION data
The table below lists the cases that can arise during power-up in conjunction with the non-
volatile SIMOTION data and explains how they are handled.
Table 3-3 Cases: Power-up with non-volatile SIMOTION data
Cas Initial condition
e
1 The non-volatile SIMOTION data are valid
2 The non-volatile SIMOTION data are invalid and there is
no backup file (PMEMORY.XML) and no backup copy of
the backup file (PMEMORY.BAK).
3 The non-volatile SIMOTION data are invalid and a
backup file (PMEMORY.XML) exists and is valid
4 The non-volatile SIMOTION data are invalid, the backup
file is invalid and there is no backup copy of the backup
file (PMEMORY.BAK).
5 The non-volatile SIMOTION data are invalid; a backup
file exists, but it is invalid; a backup copy of the backup
file exists and is valid.
Non-volatile SIMOTION data diagnostics
Users can determine the status of non-volatile SIMOTION data by reading the diagnostic buffer
and the system variables.
Evaluating via the diagnostic buffer
When they are issued, the following messages are entered once in the diagnostic buffer:
Table 3-4 Messages of the diagnostic buffer
Entry
Non-volatile data loaded from file
(Persistent Data File Loading done)
Non-volatile data loaded from the backup file
(Persistent Data Backup File Loading done)
Error while loading non-volatile data from a file
(Persistent Data File Loading Failure)

Result
Startup of SIMOTION D410 with the non-volatile
SIMOTION data. The PROFIBUS address in non-volatile
data are therefore valid, for example.
SIMOTION D410 copies the factory defaults to its non-
volatile SIMOTION data and restarts using this data. In this
case, for example, the default PROFIBUS address is used.
SIMOTION D410 copies the contents of the backup file to
its non-volatile SIMOTION data and starts using this data.
SIMOTION D410 copies the factory defaults to its non-
volatile SIMOTION data and restarts using this data. The
default PROFIBUS address is valid in this case, for
example.
SIMOTION D410 copies the contents of the backup file to
its non-volatile SIMOTION data and starts using this data.
Meaning
Non-volatile SIMOTION data has been
successfully restored from the backup
file on the CF card.
Non-volatile SIMOTION data has been
successfully restored from the backup
copy of the backup file on the CF card.
Backup file or backup copy could not be
loaded.
Possible causes:
● Backup file or backup copy not
available
● Invalid data in backup file
Remedy
-
-
Use the
_savePersistentMemoryData
system function to generate a
backup file with valid contents.
