Using I/O Messaging
Chapter 6 provides information and examples that explain how to
use I/O Messaging to control an MD65 drive.
6.1 About I/O Messaging
On DeviceNet networks, I/O Messaging is used to transfer the data
that controls the MD65 drive and sets its Reference.
The DeviceNet module provides many options for configuring and
using I/O, including the following:
• The size of I/O can be configured by selecting the number of
attached drives (Single- or Multi-Drive mode).
• Change of state, cyclic, or polled data exchange methods can be
used.
Chapter 4, Configuring the DeviceNet Module, and chapter 5,
Configuring the Scanner, discuss how to configure the DeviceNet
module and scanner 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.
