Using the I/O
Chapter 5
Depending on the controller being used, the I/O connection can be disabled by:
•
Inhibiting the module in RSLogix 5000 or Logix Designer software
•
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 520-series 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
Logic Command/Status Words: PowerFlex 525 Drives
to view details.
CompactLogix Example
Creating Ladder Logic Using the Drive Add-On Profiles in RSLogix
5000 or Logix Designer Software
Since the drive Add-On Profile automatically created descriptive controller tags
(see
) for the entire
Configuring the I/O on page 39
, 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 68
) and a ladder logic program
that will pass the Controller tag data to the Program tags.
