6.3.2 Creating backup copies (project/CF)
Prerequisite
Before adapting the project, it is essential that you create the following backup copies:
●
A backup copy of the project and
● a backup copy of the CompactFlash Card contents, refer to Saving the CompactFlash Card
data (Page 190).
6.3.3 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 were 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:
● Remanent global device variables and unit variables, as well as TO retain data (V4.1 and
higher) that are located in the FRAM of the control
● Data saved with _saveUnitDataSet or _exportUnitDataSet, and which are located on the
CF 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) remain 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
● A SIMOTION D410 service selector switch, or SIMOTION IT web server.
For information on this, see Section Diagnostic data and non-volatile SIMOTION data
(Page 203)
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.
