The C-Plug - Siemens SCALANCE X-200 Operating Instructions Manual

Description of the device

2.4 The C-PLUG

2.4 The C-PLUG
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 an IE
Switch 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.
If a C-PLUG is inserted, the configuration stored internally on the basic device is no longer
changed. Al changes made to the configuration during ongoing operation are only stored on
the C-PLUG.
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 device. 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.
