● Never switch off the SIMOTION D Control Unit during write accesses to the CF card. If the
SIMOTION D Control Unit is switched off during write accesses, this can result in destruction
of the data and, in the worst case, to damage to the file system (FAT Table = directory) on
the CF card.
If the FAT table is destroyed, the CF card will have to be reformatted and the firmware/user
data reloaded. During this process the licenses remain on the CF card.
The FAT table can be destroyed if updating the FAT table is interrupted by switching off
the SIMOTION D Control Unit. The FAT table is updated, for example, by functions such
as _exportUnitDataSet, copy RAM to ROM, or save SINAMICS NVRAM data via p7775.
The FAT table can also be destroyed if you pull a CF card out of a CF card adapter while
Windows is accessing the CF card.
● The following functions do not update the FAT table:
– _saveUnitDataSet (writing the data to an existing file)
– savePersistentMemoryData (as of V4.4: writing the data to an existing file)
Once the backup files have been created with _saveUnitDataSet /
savePersistentMemoryData, this also results in updating the FAT table.

Card reader for CF cards
Because of the quickly changing market and the large differences in the quality of card readers,
no specific recommendation can be made (except for the following card reader).
If problems occur identifying the CF card, this may be due to an incorrect power up of the card
reader.

License key on the CF card
Depending on the type and number of runtime functions used in the project, licenses must be
purchased as part of the licensing procedure for SIMOTION.
For further information on the licensing of runtime functions, see (https://
support.industry.siemens.com/cs/en/en/view/42014324)
The licenses required for SIMOTION D are assigned to an individual license key for the CF
card (license key cannot be transferred to another CF card).
The license key must be stored in the \KEYS\SIMOTION directory in the keys.txt file on the
CF card.
