PLC-5C Applications
Chapter 5 provides information and examples that explain how to use
I/O Messaging and Explicit Messaging to control, configure and monitor
a PowerFlex drive using a PLC-5C.
On ControlNet, I/O messaging is 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 drives.
The ControlNet adapter provides 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.
Chapter 3 , Configuring the Adapter and Chapter 4 , RSNetWorx
Configuration for PLC-5C Applications 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.
