4.2 SCALANCE X208

4.2.7 C-PLUG Configuration Memory

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 end 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 written to in a new basic device

requiring a different configuration, you must format the C-PLUG using the delete function in

Web Based Management following device startup. 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.

Diagnostics

Inserting a C-PLUG that does not contain the configuration of a compatible device type,

inadvertently removing the C-PLUG, or general malfunctions of the C-PLUG are indicated by

the diagnostic mechanisms of the switch (LEDs, PROFINET, SNMP, WBM, etc.).

Inserting in the C-PLUG Slot

The C-PLUG is not supplied with the devices of the SCALANCE X-200 product line. It is

available as an optional accessory.

The slot for the C-PLUG is located on the back of the device.

To insert the C-PLUG, remove the screw cover. The C-PLUG is inserted in the receptacle.

The screw cover must then be closed correctly.
