ControlLogix Controller
Example You can use any of RSLogix 5000 software versions to create the ladder
logic. These are described in separate sections below. If your version of
RSLogix 5000 software supports drive Add-on Profiles, we recommend that
you use this method.
Creating Ladder Logic Using the RSLogix 5000 Drive Add-on Profiles,
Version 16.00 or Later
Because the drive Add-on Profile automatically created descriptive controller
tags (
Figure 4.2 ) for the entire I/O image in Chapter 4 , 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, and so forth) to operate the drive and view its status, you will
need to create descriptive user-defined Program tags (
Figure 5.1 ) and a ladder
logic program that will pass the Controller tag data to the Program tags.
Figure 5.1 ControlLogix Program Tags for Drive Add-on Profile Ladder Logic
Program Example
An example ladder logic program that uses the automatically-created
descriptive Controller tags and passes their data to the user-defined Program
tags is shown in
Figure 5.2 and Figure 5.3 . Note that the prefix for the drive
Controller tags is determined by the name assigned when configuring the
I/O (
Chapter 4 ).
Depending on the drive being used, see one of the following subsections for
information on speed Reference and Feedback scaling.
