Backing up licenses, retain data, and user data
Prior to upgrading/downgrading firmware, as a precaution we would generally recommend
backing up the entire contents of the CompactFlash Card to the PC/programming device
using the card adapter and Windows Explorer.
How you should proceed when it comes to backing up and subsequently restoring data on
the CompactFlash Card depends on whether licenses and/or other retain data and user data
required are located on the CompactFlash Card.
If the CompactFlash Card contains no licenses and no other retain data or user data
required
You do not need to take any steps in this case. Delete the contents of the CompactFlash
Card and upgrade the firmware as described.
If the CompactFlash Card contains licenses (e.g. axis licenses)
Before upgrading the new firmware, back up the "KEYS" directory to your PC. This can then
be copied back to the CompactFlash Card once you have installed the new firmware.
Note
The license key is stored in the "KEYS" directory on the CompactFlash Card. When the
SIMOTION device starts up for the first time (firmware version V4.1 or higher), the license
key is saved in the boot sector of the CompactFlash Card.
A license key saved in the boot sector cannot be deleted by means of a user operation; nor
can it be deleted by formatting the CompactFlash Card or rewriting the bootloader.
If the Keys.txt file is no longer present on the CompactFlash Card (because the "KEYS"
directory has been deleted, for example), it will be written again from the boot sector to the
"KEYS" directory while the SIMOTION device is starting up. The license key can be changed
at any time (by relicensing, for example). When the device is next started up, the license key
will be saved in the boot sector again.
If you should lose the license key, you can access it again via the Web License Manager on
the Internet, at Internet address (http://www.siemens.com/automation/license). You require
the HW serial number printed on the CompactFlash Card to do this. In the Web License
Manager, you have the option of displaying the corresponding license key.
If the CompactFlash Card contains other required retain data/user data
If you are using your application to back up data to the CompactFlash Card, you must back
them up before upgrading the new firmware.
Example:
● Backing up retain data (non-volatile data saved using _savePersistentMemoryData):
● Backing up IT DIAG user files, settings (e.g. trace.xml), task trace data, log files, and
