3.1.4 C-PLUG (Configuration Plug)
Area of Application
The C-PLUG is an exchangeable medium for storage of the configuration data of
the modular switch and ships with the product. This means that the configuration
data remains available if the basic device is replaced.
Notice
The C-PLUG must only be removed or inserted when the power supply to the de-
vice is turned off.
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 or deleted with the Clean function) is in-
serted, all the configuration data of the SCALANCE X414-3E is saved to it auto-
matically when the device starts up. Changes to the configuration during operation
are saved on the C-PLUG without operator intervention if this is in the ACCEPTED
status.
