Chapter 5 Using the I/O
Logic Command/Status Words
These examples use the Logic Command word and Logic Status word for
PowerFlex 70/700 drives. See
Appendix D to view details. The definition of the
bits in these words may vary if you are using a different DPI device. See the
documentation for your device.
ControlLogix Controller
Example
Creating Ladder Logic Using the RSLogix 5000 Device Add-on
Profiles, Version 16.00 or Later
Because the device Add-on Profile automatically created descriptive controller tags
(
Figure 9 ) for the entire I/O image in Chapter 4 , you can use these tags to directly
control and monitor the device without creating any ladder logic program.
However, if you intend to use Human Machine Interface devices (PanelView, and
so forth) to operate the device and view its status, you will need to create descriptive
user-defined Program tags (
Figure 19 ) and a ladder logic program that will pass the
Controller tag data to the Program tags.
Figure 19 - ControlLogix Program Tags for Device 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 20 and Figure 21 . Note that the prefix for the device Controller tags is
determined by the name assigned when configuring the I/O ( Chapter 4 ).
