NOTICE
Irrevocable data deletion due to incorrect CF card with stored device serial number
A module replacement is detected only on the basis of the changed serial number.
Inserting the wrong CF card with saved device serial number has the following consequences:
● The non-volatile data on the device is permanently deleted.
● The IP/DP address set in the device is deleted. You can no longer go online via the IP/DP
address set originally.
Make sure that the correct CF card is inserted into the SIMOTION D4x5‑2.
Error scenarios
In the event of an error, a diagnostic buffer entry signals that it was not possible to determine
whether a module has been replaced.
Possible reasons are:
● The serial number of the device cannot be determined.
● The serial number saved on the CF card cannot be determined, for example, due to a
corrupt file system.
● The controller has not powered up.
● The new serial number could not be transferred to the CF card, for example, due to a corrupt
file system.
Restart after reloading
The system variable device.startupData.operationMode is used to define whether the
SIMOTION D4x5-2 control unit goes into the RUN state or the last operating state after a power-
on/restart.
Possible values of device.startupData.operationMode:
LAST_OPERATION_MODE [0] (default setting)
RUN [1]
With LAST_OPERATION_MODE [0], the module remains in the STOP state after reloading
the non-volatile SIMOTION data and must be switched manually to the RUN state with SCOUT,
the web server, or the mode selector.
With RUN [1], the module goes automatically into the RUN state after reloading.
SINAMICS module replacement
A module replacement is detected as of SINAMICS V4.5.
For the SINAMICS Integrated, CX32-2 and SINAMICS S120 CU310-2/CU320-2, a module
replacement is also identified via the serial number. Non-volatile SINAMICS data (NVRAM
data) backed up previously via the CU parameter p7775 on the CF card, is then automatically
transferred to the control unit.
