Appendix B
Tag Definitions
This appendix describes the tags that are used for standard, diagnostic, and fast
input and output modules.
Module-defined data types and tags are created when a module is initiated. The
set of tags associated with any module depends on the type of module and the
communication or connection format chosen during configuration.
Standard and Diagnostic
Input Module Tags
ControlLogix standard and diagnostic input modules have two types of tags:
• Configuration—Structure of data sent from the controller to the I/O
module upon powerup.
•Input—Structure of data continually sent from the I/O module to the
controller containing the current operational status of the module.

The table lists all possible standard and diagnostic input module tags. In each
application, the series of tags varies, depending on how the module is
configured.
