The module provides information on diagnostics and troubleshooting in the
following forms:
ƒ Status data values are transferred from the module to the processor.
ƒ Data contained in the module can be viewed through the
Configuration/Debug port attached to a terminal emulator.
ƒ LED status indicators on the front of the module provide information on the
module's status.
4.1 Reading Status Data from the Module
The MVI56-DEM module returns a status data set to the ControlLogix processor
in read blocks for each channel and for the whole module. This data is
transferred to the ControlLogix processor continuously.
The Configuration/Debug port provides the following functionality:
ƒ Full view of the channel read and write data
ƒ View of the module's and channel status data
ƒ View of the real-time PV and SV values
ƒ Version Information
ƒ Control over the module (cold boot)
4.1.1 The Configuration/Debug Menu
The Configuration and Debug menu for this module is arranged as a tree
structure, with the Main Menu at the top of the tree, and one or more sub-menus
for each menu command. The first menu you see when you connect to the
module is the Main menu.
Because this is a text-based menu system, you enter commands by typing the
command letter from your computer keyboard in the terminal application (for
example, HyperTerminal). The module does not respond to mouse movements
or clicks. The command executes as soon as you press the command letter —
you do not need to press
[Enter]
. When you type a command letter, a new
screen will be displayed in your terminal application.
