Input/Output Instructions (MSG, GSV, SSV, IOT) Chapter 4
AddOnInstructionDefintion Attributes
The AddOnInstructionDefinition object lets you customize instructions for sets
of commonly-used logic, provides a common interface to this logic, and provides
documentation for the instruction.
For details, see the Logix5000 Controllers Add-On Instructions Programming
Manual, publication 1756-PM010.

Attribute Data Type Instruction Description
Audit Value DINT[2], LINT GSV The audit value is a unique value that is generated when a project is downloaded to the controller
or loaded from removable storage. When a change is detected, this value is updated.
To specify which changes are monitored, use the ChangesToDetect attribute.
Note: We recommend using the DINT[2] data type to avoid limitations when working with LINT
data types in Rockwell Automation controllers.
ChangesToDetect
See Table 3
DINT[2], LINT GSV, SSV Used to specify which changes are monitored. When a monitored change occurs, the Audit Value
is updated.
Note: We recommend using the DINT[2] data type to avoid limitations when working with LINT
data types in Rockwell Automation controllers.
