Chapter 5 Control I/O
A Logix5000 controller establishes direct or rack-optimized connections to
communicate with I/O modules. Digital I/O modules support either connection
type, but analog I/O modules support only direct connections.
You must complete these tasks before your controller can communicate with
distributed I/O modules over an EtherNet/IP network:
• Set the IP addresses for each EtherNet/IP communication module.
• Connect all wiring and cabling.
• Configure a communication driver (such as AB-ETHIP-1) for the
programming workstation.
Add Distributed I/O To communicate with distributed I/O modules, add the following components
to the controller’s I/O Configuration folder:
• Local EtherNet/IP communication module
• Remote adapter
• I/O modules in the same chassis as the remote adapter
Within the folder, organize the modules into a hierarchy (tree/branch, parent/
child).
This graphic shows a system that uses a 1756-EN2TR module as the local
communication module, a remote 1794-AENT adapter and distributed
FLEX I/O modules.
