User-Defined Data Types (UDTs)

User-defined data types (UDTs) allow you to organize collections of data types
into groupings. You can use these groupings, or data type structures, to declare
the data types for controller tag structures. Another advantage of defining a UDT
is that you may reuse it in other controller tag structures that use the same data
types.
The Add-On Instruction for the MVI69E-MBS module has pre-defined UDTs. You
can find them in the User-Defined subfolder, located in the Data Types folder in
the Controller Organizer pane of the main RSLogix window. Like the controller
tags, the UDTs are organized in a multiple-level tree structure.

5.2.1 MVI69E-MBS User-Defined Data Types

Twenty different UDTs are defined for the MVI69E-MBS Add-On Instruction. The
main UDT, MBSMODULEDEF, contains all the data types for the module and
was used to create the main controller tag structure, MBS. There are five UDTs
one level below MBSMODULEDEF. These lower-level UDTs were used to create
the MBS.CONFIG, MBS.DATA, MBS. CONTROL, MBS.STATUS, and MBS.UTIL
controller tag structures.
