Setting the IP Network
Address
An EtherNet/IP communication auxiliary module ships with DHCP enabled.
You can set the network Internet Protocol (IP) address by using the following:
• EtherNet/IP node address selection switches
• Bootstrap Protocol (BOOTP)/Dynamic Host Configuration Protocol
(DHCP) server
For example, use the Rockwell Automation BOOTP-DHCP Server
Utility, which is included with Rockwell Software’s RSLinx™ Classic
software.
• Web browser and MAC scanner software
EtherNet/IP Node Address Selection Switches
The EtherNet/IP communication auxiliary module comes with three node
address selection switches that allow you to select the last octet for the IP
address 192.168.1.xxx.
Network Parameter Description
Host Name
A host name is part of a text address that identifies the module. The full
text address of a module is: host_name.domain_name.
Domain Name
A domain name is part of a text address that identifies the domain in
which the module resides. The full text address of a module is:
host_name.domain_name. The domain name has a 48-character limit.
Primary DNS Server Address This identifies any DNS servers used in the network. You must have a DNS
server configured if you specify an SMTP server with a name. The DNS
server converts the domain name or host name to an IP address that can
be used by the network.
For more information on DNS addressing, See page 27.
