Configure the Module for Your EtherNet/IP Network Chapter 5
Set the Network Address The I/O block ships with the rotary switches set to 999 and DHCP enabled. To
change the network address, you can do one of the following:
1. Adjust the switches on the front of the module.
2. Use a Dynamic Host Configuration Protocol (DHCP) server, such as
Rockwell Automation BootP/DHCP.
3. Retrieve the IP address from nonvolatile memory.
The I/O block reads the switches first to determine if the switches are set to a
valid number. Set the network address by adjusting the 3 switches on the front of
the module. Use a small blade screwdriver to rotate the switches. Line up the
small notch on the switch with the number setting you wish to use. Valid settings
range from 001…254.
Network Address Example
When the switches are set to a valid number, the I/O block’s IP address is
192.168.1.xxx (where xxx represents the number set on the switches). The I/O
block’s subnet mask is 255.255.255.0 and the gateway address is set to 0.0.0.0.
When the I/O block uses the network address set on the switches, the I/O block
does not have a host name assigned to it or use any Domain Name Server.
If the switches are set to an invalid number (for example, 000 or a value greater
than 254, excluding 888), the I/O block checks to see if DHCP is enabled. If
DHCP is enabled, the I/O block asks for an address from a DHCP server. The
DHCP server also assigns other Transport Control Protocol (TCP) parameters.
If DHCP is not enabled, and the switches are set to an invalid number, the I/O
block uses the IP address (along with other TCP configurable parameters) stored
in nonvolatile memory.
Use the Rockwell
Automation BootP/DHCP
Utility The Rockwell Automation BootP/DHCP utility is a standalone program that
incorporates the functionality of standard BootP/DHCP software with a user-
friendly graphical interface. It is located in the Utils directory on the
RSLogix 5000 installation CD. The module must have DHCP enabled (factory
default and the network address switches set to an illegal value) to use the utility.
To configure your module using the BootP/DHCP utility, perform the following

before you can adjust the
address settings.
