Chapter 6 Control I/O
The Logix5000 controller can communicate with each I/O module directly
(direct connection). Or you can configure a rack-optimized connection to the
EtherNet/IP adapter to send data to any digital I/O modules. Analog modules
always require direct connections.
You must:
• set the IP addresses for each
EtherNet/IP module.
• connect all wiring and cabling properly.
• configure the communication driver (such as AB-ETHIP-1) for the
programm
ing workstation.
Add Distributed I/O
To communicate with a system’s I/O modules, add bridge, adapter, and I/O
modules to the controller’s I/O Configuration folder. Within the folder,
organize the modules into a hierarchy (tree/branch, parent/child).
For a typical distributed I/O network, such as the one shown below,
you build the I/O configuration with the following steps.
1. Add the local comm
unication module, that is, the bridge.
2. Add the remote adapter for the distributed
I/O chassis or DIN rail.
