Set the Network Address
The adapter ships with the thumbwheel switches set to 999 and DHCP enabled.
You can set the network Internet Protocol (IP) address in these ways:
• Use the thumbwheel switches on the module.
• Use a Dynamic Host Configuration Protocol (DHCP) server, such as
Rockwell Automation® BootP/DHCP.
• Retrieve the IP address (if previously set) from nonvolatile memory.
The adapter reads the thumbwheel switches first to determine if the switches are
set to a valid number. You set the node address by using the three-position
IMPORTANT
We recommend connecting the module to the network via a 100 MB full-
duplex switch, which will reduce network collisions and lost packets, and
increase bandwidth. For detailed Ethernet connection information, see
these publications:
• Ethernet/IP Performance and Application Guide, publication ENET-
AP001
• Ethernet/IP Media Planning and Installation Guide, publication
number ENET-IN001
• Precautions to Increase the Noise Immunity of the 1794-AENT FLEX I/
O Ethernet/IP Adapter System, KnowBase Technote ID 42604
IMPORTANT
Do not wire more than 2 conductors on any single terminal.
When connecting wiring, torque terminal screws B, C, D, and E to 0.8 N•m
(7 lb-in).
