Organize Tags

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:

• organize your data to mirror your machinery

• document (through tag names) your application as you

develop it

When you create a tag, you assign the following properties to the tag:

• tag type

• data type

• scope

For more information...

The Logix5000 Controllers Common Procedures Manual, 1756-PM001

provides information on how to:

• define tags

• create tags, arrays, and user-defined structures

• address tags

• create aliases to tags

• assign indirect addresses
