Siemens SCALANCE XM-400 Configuration Manual page 231

● Device Type
Shows the device type within the product line that used the C-PLUG or KEY-PLUG
previously.
● Configuration Revision
The version of the configuration structure. This information relates to the configuration
options supported by the device and has nothing to do with the concrete hardware
configuration. This revision information does not therefore change if you add or remove
additional components (modules or extenders), it can, however, change if you update the
firmware.
● File System
Displays the type of file system on the PLUG.
● File System Size
Displays the maximum storage capacity of the file system on the PLUG in bytes.
● File System Usage
Displays the storage space in use in the file system of the C-PLUG in bytes.
● Info String
Shows additional information about the device that used the PLUG previously, for example,
order number, type designation, and the versions of the hardware and software. The
displayed software version corresponds to the version in which the configuration was last
changed. With the "NOT ACCEPTED" status, further information on the cause of the
problem is displayed.
● Firmware on PLUG
When the function enabled, the firmware will be stored on the PLUG. This means that
automatic firmware updates/downgrades can be made with the PLUG. The box "Infor
String" shows whether or not the firmware is stored on the PLUG.
● "Modify PLUG
Select the setting from the drop-down list. You have the following options for changing the
configuration on the C-PLUG or KEY-PLUG:
– Write Current Configuration to the PLUG
– Erase PLUG to factory default

NOTICE
New file system UBI
As of firmware version 3.0, UBI is the standard file system for the C-PLUG or KEY-PLUG.
If a C-PLUG with the previous file system IECP is detected in such a device, this C-PLUG
will be formatted for the UBI file system and the data will be rewritten to the C-PLUG.
This change in the file system also occurs following a firmware update to V3.0. A
downgrade to the previous version of the firmware then presents a problem. The firmware
can neither read nor write the C-PLUG or KEY-PLUG and it is not even possible to "Erase
PLUG to Factory Default".
This option is available only if the status of the PLUG is "NOT ACCEPTED" or
"FACTORY".
The configuration in the internal flash memory of the device is copied to the PLUG.
Deletes all data from the C-PLUG and triggers low-level formatting.
