Startup and non-volatile data
The table below describes the startup situations which may develop in terms of the non-
volatile data and how to handle such situations.
Table 2-3
Startup situations with non-volatile data
Situa
tion
Initial condition
Result
1
Valid contents of non-volatile data.
Startup of SIMOTION D410 with the non-volatile data.
The PROFIBUS address in non-volatile data is
therefore valid, for example.
2
Invalid contents in non-volatile data, and neither a backup
file (PMEMORY.XML), nor a backup copy
(PMEMORY.BAK) exists.
SIMOTION D410 copies the factory defaults to its non-
volatile data and restarts using this data. The default
PROFIBUS address is valid in this case, for example.
3
Invalid contents in non-volatile data. A backup file
(PMEMORY.XML) with valid contents is available.
SIMOTION D410 copies the contents of the backup file
to its non-volatile data and starts using this data.
4
Invalid contents in non-volatile data and in the backup file,
and a backup copy (PMEMORY.BAK) is not available.
SIMOTION D410 copies the factory defaults to its non-
volatile data and restarts using this data. The default
PROFIBUS address is valid in this case, for example.
5
Invalid contents in non-volatile data and in the backup file,
and a backup copy (PMEMORY.BAK) with valid contents
is available.
SIMOTION D410 copies the contents of the backup file
to its non-volatile data and starts using this data.
Diagnostics of non-volatile data
Users can determine the status of non-volatile data by reading the diagnostics buffer and the
system variable.
The following message events are entered once in the diagnostics buffer when they occur:

Messages of the diagnostics buffer
Entry
Meaning
To correct or avoid errors
Non-volatile data loaded from file
(Persistent Data File Loading done)
(Persistent Data File Loading done)
Non-volatile data successfully restored
from the backup file to the
CompactFlash Card.
-
Non-volatile data loaded from the backup file
(Persistent Data Backup File Loading done)
(Persistent Data Backup File Loading done)
Non-volatile data successfully restored
from the backup copy to the
CompactFlash Card.
-
Error while loading non-volatile data from a
file
(Persistent Data File Loading Failure)
(Persistent Data File Loading Failure)
Backup file or backup copy could not be
loaded.
Possible causes:
•
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.
