7.3 Adapting a project (Upgrading the project / Replacing the SIMOTION controller)
SIMOTION D4x5-2
320 Commissioning and Hardware Installation Manual, 02/2012
7.3.2 Backing up user data (backup variables)
Overview
With the SCOUT functions "Save variables" and "Restore variables", you have the option of
backing up and restoring data that was changed during operation and only stored in the
runtime system. This is necessary if a SIMOTION platform is changed or a version
upgraded, for example.
The "Save variables" function creates XML files which are stored in a folder of your choice.
The following types of data can be backed up:
● Retentive global device variables and unit variables, as well as TO retain data (as of
V4.1), located in the SRAM or NVRAM depending on the controller
● Data saved with _saveUnitDataSet or _exportUnitDataSet and located on the
CompactFlash card.
Note
When performing an upgrade with a firmware version that is ≥ V4.1, this function is 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.
SIMOTION retain data can also be easily backed up to a memory card without the use of
SIMOTION SCOUT. For this purpose, use:
• The _savePersistentMemoryData function or
• The Service selector switch or DIAG button on the SIMOTION D4x5-2 or IT DIAG
See also Section Backing up diagnostic data and no
n-volatile SIMOTION data
(Page 359).
Procedure
The backup of the user data must be performed before the upgrade of the SCOUT project.
This is possible for a version upgrade with the "old" SCOUT version or the "new" SCOUT
version.
