3.18 C-PLUG (configuration plug) for SCALANCE X-200
Area of application
The C-PLUG is an exchangeable medium for storage of the configuration and project
engineering data of the basic device. This means that the configuration data remains
available if the basic device is replaced.
How it works
Power is supplied by the basic device. The C-PLUG retains all data permanently when the
power is turned off.
If an empty C-PLUG (factory settings) is inserted, all configuration data of the
SCALANCE X-200 is saved to it when the device starts up. Changes to the configuration
during operation are also saved on the C-PLUG without any operator intervention being
necessary.
A basic device with an inserted C-PLUG automatically uses the configuration data of the
C-PLUG when it starts up. This is, however, only possible when the data was written by a
compatible device type.
This allows fast and simple replacement of the basic device. If a device is replaced, the C-
PLUG is taken from the failed component and inserted in the replacement. The first time it is
started up, the replacement device has the same configuration as the failed device except
for the MAC address set by the vendor.
Using a previously written C-PLUG
If you want to insert a C-PLUG that has already been used and has been written to a basic
device with a different configuration, the existing C-PLUG data must first be deleted.
Note
The device normally starts up with the configuration of the C-PLUG, assuming this was
written to by a compatible device type.
The C-PLUG must now be deleted in "C-PLUG Information" menu of Web Based
Management or the configuration of the device must be copied to the C-PLUG. The device
starts up with the new configuration of the device only after the device has restarted.
If the C-PLUG was written by an incompatible device type, the basic device will not start up
fully and signals an error. The delete function can nevertheless be used. When the device
next starts up, the current configuration data of the basic device is written to the C-PLUG.
