FLEX I/O EtherNet/IP Adapters Installation Instructions
Set the Network Address
The adapter ships with the thumbwheel switches set to 999 and DHCP enabled. Set the network Internet Protocol (IP) address in these ways:
• Use the thumbwheel switches on the module.
• Use a Dynamic Host Configuration Protocol (DHCP) server, such as Rockwell Automation® BootP/DHCP.
• Retrieve the IP address (if previously set) from nonvolatile memory.
The adapter reads the thumbwheel switches first to determine if the switches are set to a valid number. Set the node address by using the three-position thumbwheel switch. Press
the + or - buttons to change the number. Valid settings are 001…254.
When the switches are set to a valid number, the IP address of the adapter is 192.168.1.xxx (where xxx represents the number set on the switches). The subnet mask of the adapter
is 255.255.255.0 and the gateway address is set to 0.0.0.0. The adapter does not have a host name assigned, or use any Domain Name System when using the thumbwheel settings.
Network Address Thumbwheel
If you set the switches to an invalid number (such as 000, or a value greater than 254), the adapter checks to see if you enabled DHCP.
The switch value of 888 lets you reset all configuration parameters to the factory settings. This is useful in situations where you want to reuse a module that has an unknown
configuration.

, for more information.
DHCP Enabled and Not Enabled
If DHCP is Then the adapter
Enabled Asks for an address from a DHCP server. The DHCP server also assigns other Transport Control Protocol (TCP) parameters.
Not enabled Uses the IP address (along with other TCP configurable parameters) stored in nonvolatile memory.
