Set the Network Address
The adapter ships with the rotary network address switches set to 999 and DHCP
enabled. To change the network address, you can:
• adjust the switches 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 adapter reads the switches first to determine if the switches are set to a valid number.
You 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.
When you use the switches to assign an address and set it to 001, the adapter gateway
address is set to 0.0.0.0. and the subnet mask is 255.255.255.0 . When you use the
switches to assign an address and set it between 002...254, the adapter gateway address is
set to 192.168.1.1.
The adapter does not have a host name assigned, or use any Domain Name System when
using the switch settings.
Network Address Switches
Refer to publication POINT I/O and ArmorPOINT I/O Dual Port EtherNet/IP
Adapter User Manual,
1734-UM017 for more information on adapter configuration.
If you set the switches to an invalid number (for example, 000 or a value greater than 254
excluding 888), the adapter checks to see if you enabled DHCP.
DHCP Enabled and Not Enabled
DHCP State Adapter Action
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.
This example shows the
network address set at 163.
