Using the I/O
This chapter provides information and examples that explain how to control,
configure, and monitor a PowerFlex 520-series drive using the configured I/O.
About I/O Messaging On CIP-based networks, including EtherNet/IP, 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 520-series
drives.
The adapter includes the Logic Command, Logic Status, Reference, Feedback,
and memory allocation for the Generic Ethernet module profile (all as 16-bit
words) in the controller’s I/O image. This basic I/O must always be configured in
the Ethernet bridge using RSLogix 5000 or Logix Designer software. Additional
I/O, if needed, can be set using up to four Datalinks to write data and/or up to
four Datalinks to read data. When using any combination of these Datalinks, add
one 16-bit word for each Datalink to the basic I/O Input Size and/or Output
Size.
Configuring the Adapter on page 25 and Configuring the I/O on page 39 discuss
how to configure the adapter and controller on the network for the required I/O.
The Glossary defines the different options. This chapter discusses how to use I/O
after you have configured the drive and controller.
