Non-descriptive Controller Tags
Creating Ladder Logic with Descriptive Tags Using RSLogix 5000
Software, Version 13.00 or Later
If the DeviceNet Tag Generator was used in Chapter 4 to automatically
create descriptive controller tags for the entire I/O image, these tags can be
used 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 Program tags (
Figure 5.9 ) and a ladder
logic program that will pass the Controller tag data to the Program tags.

TIP: If the descriptive controller tags created by the DeviceNet Tag
Generator are not properly named, the correct EDS file may not have been
used. The DeviceNet Tag Generator will only create correct tag names if the
EDS file being used is downloaded from the website (see
Downloading the
EDS File from Rockwell Automation Website on page 4-8 )—not created
from the network.
