The module status variable <tagname> appears in the Variable field.
2) Select the channel that you want to wire to a variable.
3) Click the button next to the Channel Variable fields.
4) Choose a data structure from the three options displayed: Simple, Compact,

The Select Variables dialog box is displayed.
5) Select a named structure, click OK.

Configuring Digital Inputs
You can wire digital input channels to the following variable type and data structures:
BOOL (the <variable_name> gives the input state)
TK9_DI_Compact (provides three elements)
TK9_DI_Full (six elements)
The structures provide additional information about the input, such as line fault status
and discrepancy status. You can also define custom thresholds for digital inputs.
