4.6 C-PLUG
CPLUG (configuration plug)
The C-PLUG is an exchangeable medium for storage of the configuration and project
engineering data of the base 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-200RNA 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 needs to be replaced,
the C‑PLUG is simply 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.
Compatible devices
As a general rule, the data on the C-PLUG is only compatible with devices having an identical
order number and the same device name.
Over and above this, the data of the SCALANCE X204RNA and the SCALANCE X204RNA is
compatible.
Using a previously written C-PLUG
If you want to insert a C‑PLUG that has already been used and has been written to in a
SCALANCE X-200RNA with a different configuration, the existing C‑PLUG data must first be
deleted.
Note
The devices of the SCALANCE X200RNA product line normally start up with the configuration
of the C‑PLUG, assuming this was written to by a compatible device type.
