Using I/O Messaging
Chapter 6 provides information and examples that explain how to
use a ControlLogix controller to send I/O Messaging to control,
configure, and monitor an MD65 drive.
Important: At the time of publication, only ControlLogix
controllers are able to transmit I/O data over an
EtherNet/IP network. PLC-5

and SLC

controllers
cannot transmit EtherNet/IP I/O data. However, these
controllers can perform control using explicit
messages to the CIP Register object and PCCC N41
and N42 files.
6.1 About I/O Messaging
On EtherNet/IP networks, I/O messaging is used to transfer the
data that controls the MD65 drive and sets its Reference. I/O can
also be used to transfer data to and from Datalinks in MD65 drives.
The module provides many options for configuring and using I/O,
including configuring the size of I/O by selecting the number of
attached drives (Single or Multi-Drive mode).
Chapter 4, Configuring the Module, and chapter 5, Configuring the
Scanner or Bridge, discuss how to configure the module and
scanner or bridge on the network for these options. The Glossary
defines the different options. This chapter discusses how to use I/O
after you have configured the module and scanner or bridge.
