Using I/O Messaging
Chapter 6 provides information and examples that explain how to
use I/O Messaging to control an SP600 drive.
6.1 About I/O Messaging
On DeviceNet networks, I/O Messaging is used to transfer the data
which controls the SP600 drive and sets its Reference. I/O can also
be used to transfer data to and from Datalinks in SP600 drives.
The DeviceNet adapter provides many options for configuring and
using I/O, including the following:
• The size of I/O can be configured by enabling or disabling the
Logic Command/Reference and Datalinks.
• A master-slave hierarchy or peer-to-peer communications can be
set up.
• Change of state, cyclic, or polled data exchange methods can be
used.
Chapter 4, Configuring the DeviceNet Adapter, and chapter 5,
Configuring the Scanner, discuss how to configure the DeviceNet
adapter 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 adapter and scanner.
