Using the I/O
This chapter provides information and examples that explain how to control,
configure, and monitor a PowerFlex 750-Series drive using Profinet I/O
messaging.
About I/O Messaging Profinet I/O messaging is used to transfer the data which controls the PowerFlex
drive and sets its Reference. I/O messaging can also be used to transfer data to and
from Datalinks which are mapped to parameters in the PowerFlex 750-Series
drive.
The option module includes the Logic Command, Logic Status, Reference, and
Feedback (all as 32-bit words) in the controller's I/O image. This basic I/O must
always be configured by the Profinet configuration tool to the option module,
enabling the ability to control and monitor the PowerFlex 750-Series drive.
Additional I/O if needed, can be configured 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 Option Module , and Chapter 4 , Configuring the
Profinet Master , discuss how to configure the option module and controller on
the network for the required I/O. This chapter discusses how to use I/O after you
have configured the option module and controller.
