Using the I/O

ControlLogix Controller
Example

This section include information when using a ControlLogix controller and an
RSLogix 5000 Drive Add-on Profile or a Generic Profile.

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 6

) 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 (for example, a
PanelView graphic terminal) to operate the drive and view its status, you will
need to create descriptive user-defined Program tags (

Figure 10

) and a ladder

logic program that will pass the Controller tag data to the Program tags.

Figure 10 - 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 11

and

Figure 12

. Note that the prefix for the drive Controller tags is

determined by the name assigned when configuring the I/O (

Chapter 4

).
