Control I/O
Introduction
This chapter describes how a controller controls distributed I/O over an
EtherNet/IP network. The controller requires a communication module to
connect to the network. Distributed I/O modules require an adapter to
connect to the network.

In this example, the Logix5000 controller has an EtherNet/IP communication
module to connect to the EtherNet/IP network. The distributed (remote) I/O
has an EtherNet/IP adapter to connect it to the EtherNet/IP network.
