DHCP ("Obtain an IP address automatically") is enabled on the device as standard. So the device obtains 
its IP address from a DHCP server which is often integrated into a network switch or router. If there is no 
DHCP server, the device is assigned an automatic IP address, usually 169.254.xxx.yyy. 
Settings for the IP address are made directly in ETS, where you can also give the device a fixed address. 
If you do, please ensure that the IP is suitable for the network topology, otherwise the device cannot 
subsequently be accessed.

If you have set a fixed IP address, it will be loaded onto the device when you program the physical 
address. The logic controller is now accessible via the LAN. 
If you wish to program the device directly via LAN without a connection to the KNX bus line, select "Use 
direct IP connection if available" in Bus/Connection Options.
