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 CompactFlash 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 CompactFlash 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, IT DIAG or the mode selector switch .
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 CompactFlash card, is then
automatically transferred to the control unit.
