4.3.4 Module replacement
SIMOTION module replacement
A module replacement is detected automatically as of SIMOTION V4.3.
During a module replacement, a CompactFlash 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 D4x5-2 on the basis of the serial
number. The data backed up on the CompactFlash card with _savePersistentMemoryData is
then automatically transferred to the new device.
Note
As an additional option, you can back up the non-volatile data by setting the Service selector
switch, with the DIAG button or via IT DIAG, see Section Diagnostics data and non-volatile
SIMOTION d
ata (Page 359).
Initial power-up with the CompactFlash card
Requirement: CompactFlash card (no device serial number stored)
If the SIMOTION D4x5 2 powers up successfully with a new CompactFlash card, the serial
number of the device is stored on the CompactFlash card. In this case, a module
replacement cannot be detected.
Note
The serial number stored on the CompactFlash card remains unaffected by the following
actions:
• Copy RAM to ROM
• Project download
• Writing the CompactFlash card via the SCOUT function "Load to file system"
• FW/project update via device update tool
If the CompactFlash card contents are copied to another CompactFlash card, the serial
number is also copied.
A serial number stored on the CompactFlash card can only by removed by deleting the
CompactFlash card contents.
