Siemens SIMOTION D4x5-2 User Manual

If the SIMOTION D4x5 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.
SIMOTION D4x5-2 power-up with the CF card (no module replacement)
Requirement:
●
The same CF card
● The same controller
If the device powers up successfully, the serial number stored on the CF card is compared
with the serial number of the device.
If the serial numbers are identical, there has been no module replacement.
The device powers up. In the non-volatile SIMOTION data present in the device is valid, then
this is used (for details, see Table 5-3 Power‑up scenarios for non‑volatile SIMOTION data
(Page 110)).
SIMOTION D4x5-2 power-up with the CF card (module replacement)
Requirement:
● The same CF card
● Different device (e.g. replacement because of fault)
If the device powers up successfully, the serial number stored on the CF card is compared
with the serial number of the device.
If the serial numbers are not identical, there has been a module replacement.
This means:
● The serial number of the new module is stored on the CF card.
● The non-volatile SIMOTION data are deleted in the device.
● A diagnostic buffer entry is issued which signals that a module has been replaced.
● The non-volatile SIMOTION data stored "on the CF card" is transferred to the device (for
details, see Table 5-3 Power‑up scenarios for non‑volatile SIMOTION data (Page 110)).
