Using the I/O
This chapter provides information and examples that explain how to
control, configure, and monitor a PowerFlex 755 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 755 drives.
The adapter includes the Logic Command, Logic Status, Reference,
Feedback, and memory allocation for the Generic Ethernet module
profile (all as 32-bit words) in the controller’s I/O image. This basic I/O
must always be configured in the EtherNet bridge using RSLogix.
Additional I/O, if needed, can be set using up to 16 Datalinks to write
data and/or up to 16 Datalinks to read data. When using any
combination of these Datalinks, add one 32-bit word for each Datalink
to the basic I/O Input Size and/or Output Size.
Chapter 3 , Configuring the Adapter , and Chapter 4 ,
Configuring the I/O , 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 adapter and controller.
