Using Module Identification
and Status Information
Each ControlLogix Drive 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 located in any ControlLogix rack
at any time. While retrieving module identity, you can also retrieve
the module’s status.
Each module maintains the following information:
