Using the I/O
PowerFlex® 755 Drive Embedded EtherNet/IP Adapter User Manual
Publication 750COM-UM001A-EN-P
Depending on the controller being used, the I/O connection can be
disabled by:
•
Inhibiting the module in RSLogix 5000
•
Putting the controller in Program mode
•
Placing the scanner in idle mode
•
Disconnecting the drive from the network
DeviceLogix Datalinks are also locked while the DeviceLogix program
is running. The DeviceLogix program must first be disabled to allow
changes to the Datalinks. Set DeviceLogix parameter 53 - [DLX
Operation] to “DisableLogic” to disable the logic (the parameter value
will then change to “LogicDisabld”).
Example Ladder Logic
Program Information
The example ladder logic programs in the sections of this chapter are
intended for and operate PowerFlex 750-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 750-Series drives. Refer to
Command/Status Words for PowerFlex 750-Series Drives

ControlLogix Example
Creating Ladder Logic Using the RSLogix 5000 Add-On Drive
Profiles (v16 or higher)
Since the Add-On Drive Profile automatically created descriptive
controller tags (
) for the entire I/O image in
, 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 (
) and a ladder logic program that will pass the
Controller tag data to the Program tags.
