SIMOTION D410-2 power-up with the CF card (no module replacement)
Prerequisite is that the same CF card and the same device are used.
If the SIMOTION 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 data present in the device is valid, this will be used
(for details, see Table 5-3 Power‑up scenarios for non‑volatile SIMOTION data (Page 93)).
SIMOTION D410-2 power-up with the CF card (module replacement)
Prerequisite is that the same CF card and a different device (e.g. replacement because of a
defect) are used.
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 93)).
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 D410‑2.
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. This may have the following reasons:
● The serial number of the device cannot be determined.
● The serial number saved on the CF card cannot be determined (e.g. due to a corrupt file
system).
● The controller has not powered up.
● The new serial number could not be transferred to the CF card (e.g. due to a corrupt file
system).
