Connection to the c430 is displayed with IP address 0.0.0.0

The IP address of the controller c430 in the round brackets is displayed as 0.0.0.0. This makes it difficult to identify the device. 

Conditions under which the behavior occurs:
A connection is established to the to the controller c430 is established via the switch port (X396/X397) and at the same time the engineering interface (X16) is not used or is not connected. This results in the node name the IP address (0.0.0.0).

Short-term measures, Recommendations,Rating:
The function of the connection is not restricted. A connection can be established from the PLC Designer to the c430.
If the IP address is to be displayed for better identification, the connection must be established via the Engineering interface X16.
Alternatively, the MAC address can also be used for identification. This is printed on the c430 and is shown in the node address.

Or you can use the "Wink" function for unique identification. In this case, the LEDs of the relevant c430 flash.
