Configure the Adapter for Your
EtherNet/IP Network
Overview This chapter describes how to configure the 1794-AENTR or 1794-AENTRXT
adapter module for the ControlLogix system.
Configuration
Requirements Before you can use your 1794-AENTR or 1794-AENTRXT adapter, you must
configure its IP address, and optionally, its subnet mask and gateway address. You
can use the Rockwell BootP/DHCP utility to perform the configuration. You
can also use generic BootP software or, within some limitations, a DHCP server.
IP Address
The IP address identifies each node on the IP network (or system of connected
networks). Each TCP/IP node on a network (including the 1794-AENTR or
1794-AENTRXT adapter) must have a unique IP address.

IMPORTANT When using the BootP protocol, you must enter the Ethernet
hardware address of your adapter. Rockwell assigns each
1794-AENTR or 1794-AENTRXT adapter a unique 48-bit hardware
address at the factory. The address is printed on a label on the front
of your 1794-AENTR or 1794-AENTRXT adapter. It consists of six
hexadecimal digits separated by colons. This address is fixed by the
hardware and cannot be changed.
If you change or replace the 1794-AENTR or 1794-AENTRXT adapter,
you must enter the new Ethernet hardware address of the adapter
when you configure the new adapter.
