14.2.1 Addressing via DHCP
In this application example, the IP address is set via DHCP using the software tool "BootP/DHCP-Server"
version 2.3.2.0 from Rockwell Automation.
Addresses in the range from 1 to 254 can be allocated. The addresses 0 and 255 are reserved for
broadcast messages in the subnet.
After having been connected to the network, the BL20 sends DHCP requests to the server using its
MAC-ID.

The rotary coding switches on the gateway must be set to "300" = BootP, "400" = DHCP or
"600" = PGM-DHCP in order to enable the BootP/DHCP-Mode.
