Status Variables for Digital Output Modules
The 9451 digital output module provides a number of status variables that are available
to the application. The 9451 Variables Editor presents the variables in two collections,
which it calls 'racks': Status Booleans, and Power Status Integers.
Wire Status Variables to a Digital Output Module
To wire a status variable to a digital output module do the following:
1) Navigate to the digital output module in the equipment tree view.
2) Select the Variables tab of the 9451 Module Editor.

The 9451 Variables Editor dialog box opens.
3) Select a rack. The editor displays a list of associated variables.
Note: The status variables are for modules, not channels. The column headed
'Channel' shows an index for the variables; it does not relate to individual digital
outputs.
4) Select a variable.
5) Click the button. The Select Variable dialog box opens.
6) From the list select an application variable to wire to the status variable, click OK.
7) Repeat for each subsequent variable to be wired.
8) Return to the 9451 Variables Editor and click Apply. The variable will now be
wired.
