Using I/O Messaging
Chapter 5 provides information and examples that explain how to use
I/O Messaging to control a PowerFlex 40 drive.
On DeviceNet, I/O Messaging is used to transfer the data which controls
the PowerFlex drive and sets its Reference.
The DeviceNet adapter 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 3 , Configuring the Adapter and Chapter 4 , Configuring the
Scanner discuss how to configure the 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.
