Set the Network Address
The module ships with the rotary switches set to 999 and DHCP enabled.
To change the network address, you can do one of the following:
• adjust the switch on the front of the module.
• use a Dynamic Host Configuration Protocol (DHCP) server, such as Rockwell Automation BOOTP/DHCP.
• 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. To set the network address:
1. Rotate the three switches on the front of the module by using a small blade screwdriver.
2. Line up the small notch on the switch with the number setting you wish to use.
Valid settings range from 001…254.
The example below shows a default node address set at 163.
3. Cycle power.
When the switches are set to a valid number, the IP address is 192.168.1.xxx (where xxx represents the number set on the
switches). The subnet mask is 255.255.255.0 and the gateway address is set to 0.0.0.0. When the module uses the network
address set on the switches, it 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 module checks
to see if DHCP is enabled. If DHCP is enabled, the module asks for an address from a DHCP server. The DHCP server
also assigns other Transport Control Protocol (TCP) parameters.
If DHCP is not enabled, the IP address (along with other TCP configurable parameters) stored in nonvolatile memory is
used.
