Replacing modules in the spare part scenario

SIMOTION module replacement
During a module replacement, a CF card that contains the non-volatile SIMOTION data backed-
up with _savePersistentMemoryData, is inserted in a new device of the same type.
A module replacement is detected by the SIMOTION D410-2 on the basis of the serial number.
The data backed up on the CF card with _savePersistentMemoryData are then automatically
transferred to the new device.
Note
As an additional option, you can back up the non-volatile data by switching the service selector
switch, with the DIAG button, or via SIMOTION IT web server. For details, see Section
Diagnostic data and non-volatile SIMOTION data (Page 304).
Initial power-up with the CF card
This requires a CF card on which no device serial number is stored.
If the SIMOTION D410-2 powers up successfully with a new CF card, the serial number of the
device is stored on the CF card. In this case, a module replacement cannot be detected.
Note
The serial number stored on the CF card remains unaffected by the following actions:
● Copy RAM to ROM
● Project download
● Writing the CF card via the SCOUT function "Load to file system"
● FW/project update via device update tool
If the CF card contents are copied to another CF card, the serial number is also copied. A
serial number stored on the CF card can only by removed by deleting the CF card contents.
