Chapter 4 Using the I/O
Example of Ladder Logic
Program Information
The example ladder logic programs in this chapter are intended for and operate
PowerFlex 755T drives.
Functions of the Example Programs
The following can be accomplished by using the example programs.
• 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 755T drives. See Appendix E
, Logic Command/Status Words:
PowerFlex 755T drives and Bus Supplies to view details.
ControlLogix Controller
Example
This section includes information on how to use a ControlLogix controller,
and an RSLogix 5000 or Studio5000 drive Add-on Profile.
For information on how to use a PLC-5®, SLC™ 500, or MicroLogix™ 1100/
1400 controller or how to use the Logix controller Generic ETHERNET-
MODULE profile, see Controller Examples for EtherNet/IP network
communication with PowerFlex 750-Drives, publication 750COM-AT001
.
Create Ladder Logic Using the RSLogix or Studio 5000 with Drive
Add-on Profiles
The drive Add-on Profile automatically creates descriptive controller tags
(Figure 10
) for the entire I/O image in Chapter 3. Use these tags to control and
monitor the drive without creating any ladder logic program. However, if HIM
devices (for example, a PanelView™ graphic terminal) are used to operate the
drive and view its status, create descriptive user-defined Program tags
(Figure 14
). Also create a ladder logic program that passes the Controller tag
data to the Program tags. The drive profile that is used in RSLogix 5000
software, is version 20 and Studio 5000 environment, is version 21 or later with
Add-on Profile version 1.xx or later.
