Controller tags are a feature of the RSLogix software and are part of the MVI56E-
MNETC/MNETCXT Add-On Instruction. Refer to the section Adding the Module
to RSLogix (page 29, page 13) for information on importing the Add-On
Instruction into RSLogix.
3.1 Controller Tags
Data related to the MVI56E-MNETC/MNETCXT is stored in the ladder logic in
variables called controller tags. You use controller tags to manage
communication between the MVI56E-MNETC/MNETCXT module and the
ControlLogix processor:
 View the read and write data being transferred between the module and the
processor.
 View status data for the module.
 Set up and trigger special functions.
 Initiate module restarts (Warm Boot or Cold Boot).
Individual controller tags can be grouped into collections of controller tags called
controller tag structures. A controller tag structure can contain any combination
of:
 Individual controller tags
 Controller tag arrays
 Lower-level controller tag structures
The controller tags are included in the MVI56E-MNETC/MNETCXT Add-On
Instruction ladder logic. After you import the Add-On Instruction, you can find the
controller tags in the Controller Tags subfolder, located in the Controller folder in
the Controller Organizer pane of the main RSLogix 5000 window. This controller
tag structure is arranged as a tree structure. Individual controller tags are found
at the lowest level of the tree structure. Each individual controller tag is defined to
hold data of a specific type, such as integer or floating-point data.
The Add-On Instruction also includes user-defined data types (UDTs). UDTs are
collections of data types and declares the data types for the controller tag
structures.
