Replacing modules in the spare part scenario
SIMOTION module replacement
A module replacement is detected automatically as of SIMOTION V4.3.
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 D4x5-2 on the basis of the serial number.
The data backed up on the CF 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 SIMOTION IT web server, see Section diagnostic data and
non-volatile SIMOTION data (Page 396).
