With a Logix5000 controller, you use a tag (alphanumeric name) to address data
(variables). In Logix5000 controllers, there is no fixed, numeric format. The tag
name itself identifies the data. This lets you do the following:
• Organize your data to mirror your machinery.
• Document your application as you develop it.
This example shows data tags created within the scope of the Main Program of
the controller.
Figure 33 - Tags Example
There are several guidelines for creating and configuring program tags for optimal
task and program execution. For more information, see the Logix5000
Controllers and I/O Tag Data Programming Manual, publication 1756-PM004
