The module provides information on diagnostics and troubleshooting in the
following forms:
Status data values are transferred from the module to the processor.
Data contained in the module can be viewed through the
Configuration/Debug port attached to a terminal emulator.
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-CAS module returns a 35-word Status Data block that can be used to
determine the module's operating status. This data is located in the module's
database at registers 6000 to 6034 and at the location specified in the
configuration. This data is transferred to the ControlLogix processor continuously
with each read block. For a complete listing of the status data object, refer to the
Module Set Up
section.
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.
Navigation
All of the sub-menus for this module contain commands to redisplay the menu or
return to the previous menu. You can always return from a sub-menu to the next
higher menu by pressing
[M]
on your keyboard.
