Configure an EtherNet/IP Module to Operate on the Network Chapter 4
Set the IP Network Address
EtherNet/IP modules ship with the IP address configuration switches set to
999 and DHCP enabled. You can set the network Internet Protocol (IP)
address by:
• using the switches available on some modules.
• using a Bootstrap Protocol (BOOTP)/Dynamic Host Configuration
Prot
ocol (DHCP) server, such as the Rockwell Automation
BOOTP-DHCP server utility.
• using RSLinx software or RSLogix 5000 programming software.
IMPORTANT
The switches on 1783-ETAP, 1783-ETAP1F and
1783-ETAP2F taps are used somewhat differently than
other EtherNet/IP modules.
For more information on how to use switches on the
taps, see either of the following:
• Ethe
rNet/IP Tap Installation Instructions, pubication
1783-IN007
• EtherNet/IP Fiber Tap Installation Instructions,
publication
1783-IN008
IMPORTANT
The adapter reads the configuration switches only when
you cycle power to determine if the switches are set to a
valid number.
Valid settings range from 001...255, with some
exceptions. There are some reserved values that you
cannot use as the first octet in the address.
For example, you cannot use:
• 001
.xxx.xxx.xxx
• 127.xxx.xxx.xxx
• 223 to 255.xxx.xxx.xxx
T
o restore the factory default settings on the module, set
the switches
to 888.
