C-Plug (Configuration Plug) - Siemens SCALANCE X-300 Series Operating Instructions Manual

Description of the device

4.6 C-PLUG (configuration plug)

Error indication
● The signaling by the signaling contact is synchronized with the fault LED, in other words, all
errors displayed by this LED (freely configurable) are also signaled on the signaling contact.
● If an internal fault occurs, the fault LED lights up and the signaling contact opens.
● The connection or disconnection of a communication node on an unmonitored port does not
lead to an error message.
● The signaling contact remains activated until the error/fault is eliminated or until the current
status is entered in the fault mask as the new desired status.
4.6 C-PLUG (configuration plug)
NOTICE
DO NOT REMOVE C‑PLUG WHILE POWER IS ON
The C-PLUG may only be removed or inserted when the power supply to the device is turned
off.
In a device with a varnished printed circuit board, you may only use a C-PLUG with a
varnished board.
Area of application
The C-PLUG is an exchangeable medium for storage of the configuration data of the IE Switch
and ships with the product. This means that the configuration data remains available if the IE
Switch is replaced.
How it works
Power is supplied by the IE Switch. 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 inserted, all the
configuration data of the IE Switch is saved to it automatically when the device starts up.
Changes to the configuration during operation without operator intervention are saved on the
C-PLUG if this is in the "ACCEPTED" status.
An IE Switch with an accepted C-PLUG inserted uses the configuration data of the C-PLUG
automatically when it starts up. Acceptance is possible only when the data was written by a
compatible device type.
This allows an IE Switch to be replaced quickly and simply. 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.
