Using Module Identification
and Status Information
Each ControlLogix CFM module maintains specific identification information
that separates it from all other modules. This information assists you in
tracking all the components of your system.
For example, you can track module identification information to be aware of
exactly what modules are in any ControlLogix rack at any time. While
retrieving module identity, you can also retrieve the module’s status.
Each module maintains the information in Table 2 :
