Using the I/O
This chapter provides information and examples that explain how to
control, configure, and monitor a PowerFlex 7-Class drive using the
configured I/O.
About I/O Messaging On CIP-based networks, including DeviceNet, I/O connections are used to
transfer the data which controls the PowerFlex drive and sets its Reference.
I/O can also be used to transfer data to and from Datalinks in PowerFlex
7-Class drives.
The adapter provides many options for configuring and using I/O, including
the following:
• Configuring the size of I/O by enabling or disabling the Logic
Command/Reference and Datalinks
• Setting a Master-Slave hierarchy or a Peer-to-Peer hierarchy
• Using a Change of State, Cyclic, or Polled data exchange method
Chapter 3 , Configuring the Adapter , and Chapter 4 , Configuring the I/O ,
discuss how to configure the adapter and controller on the network for these
options. The defines the different options. This chapter discusses how to
use I/O after you have configured the adapter and controller.
