Using I/O Messaging
Chapter 5 provides information and examples that explain how to use a
ControlLogix controller to send I/O Messaging to control, configure, and
monitor a PowerFlex 40 drive.
Important: At the time of publication, only ControlLogix controllers
can make an EtherNet/IP network I/O connection as
described in this chapter; PLC-5’s and SLC’s cannot.
However, these controllers can perform control using
explicit messaging to the CIP Register object and PCCC
N41 and N42 files.
On EtherNet/IP, I/O messaging is used to transfer the data which
controls the PowerFlex drive and sets its Reference.
The EtherNet/IP adapter 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 3 , Configuring the Adapter , and Chapter 4 , Configuring the
Scanner or Bridge , discuss how to configure the adapter 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 adapter and scanner or bridge.
