Using the I/O
download or anything else that could change the makeup of the I/O connection
in a running system. The I/O connection with the controller must first be
disabled to allow changes to the respective Datalinks.
Depending on the controller being used, the I/O connection can be disabled by:
•
Inhibiting the module in RSLogix 5000/Logix Designer
•
Putting the controller in Program mode
•
Placing the scanner in idle mode
•
Disconnecting the drive from the network
Example Ladder Logic
Program Information
The example ladder logic programs in the sections of this chapter are intended for
PowerFlex 525 drives.
Functions of the Example Programs
The example programs enable you to:
•
Receive Logic Status information from the drive.
•
Send a Logic Command to control the drive (for example, start, stop).
•
Send a Reference to the drive and receive Feedback from the drive.
•
Send/receive Datalink data to/from the drive.
Logic Command/Status Words
These examples use the Logic Command word and Logic Status word for
PowerFlex 525 drives. See
to view details.

Add-On Profiles
Since the drive Add-On Profile automatically created descriptive controller tags
(see
) for the entire
, you can use these tags to directly control and monitor
the drive without creating any ladder logic program. However, if you intend to
use Human Machine Interface devices (PanelView, etc.) to operate the drive and
view its status, you will need to create descriptive user-defined Program tags (see
CompactLogix Program Tags for Drive Add-On Profile Ladder Logic Program
Example on page 65
) and a ladder logic program that will pass the Controller tag
data to the Program tags.
