Service and maintenance
7.4 Performing a firmware and project update
Case 3: The CompactFlash card contains retain data / user data which is still required
If you are using your application to back up data to the CompactFlash card, you must back
this up before installing the new firmware.
Example:
● Backup of the retain data
● Backing up IT DIAG user files, settings (e.g. trace.xml), task trace data, log files, and
Java files (classes, archives, user file system, etc.), stored in the following directories:
– user\simotion\hmicfg
– user\simotion\hmi
● Backing up configuration data for modular machines in conjunction with the
_activateConfiguration system function, stored in the following directory:
– install\simotion
● Backing up unit data (data saved on the CompactFlash card using
_saveUnitDataSet/_exportUnitDataSet), stored in the following directory:
– user\simotion\user dir\<unitname>
338
– user\simotion\pmemory.xml
For non-volatile SIMOTION data backed up with _savePersistentMemoryData
– user\sinamics\nvram\pmemory.acx or \nvram\xx\pmemory.acx
For non-volatile SINAMICS data (Integrated or CX32-2) backed up with p7775
Note
When a version is changed, you must use the "Save variables" function to back up
data saved using _saveUnitDataSet or _exportUnitDataSet in a way that is not
dependent on the version. You then have the option of restoring them using "Restore
variables".
When performing an upgrade with a firmware version that is ≥ V4.1, these two
functions are only required for backing up and restoring unit data sets that have been
created using _saveUnitDataSet.
Retain and unit data (saved with _exportUnitDataSet) remains valid even after a
version upgrade.
