3.1.3 Setting up DHCP using the front-panel
It is recommended that the IP addresses assigned to the UDA by the DHCP server are fixed, so that the
Modbus host can locate the UDA on the network. Consult your IT department or network administrator for
allocating DHCP IP addresses to specific devices.

Change the value to Enable and press enter to lock the setting into the communication card.
Once all of the UDAs are set to DHCP, power them down, connect them to the network, and then power
them up. The DHCP server should automatically assign the IP address for each UDA.
Go to the Comm Status menu in the Status Displays menu to verify that the DHCP server automatically set
the IP address.
