About this task

For information on the MUX blocks, see the Selection section in the Logic.

To configure the MUX block:


  1. Double-click a MUX block. The MUX Details dialog box appears.
  2. Select the IO Modifications check box to add or remove inputs. Adding inputs creates new Input X - Modes buttons for configuration in the left pane. Removing inputs removes the corresponding Mode button in the left pane. See Adding Inputs and Outputs to a Block or Module for detailed procedures.
  3. Click Edit.
  4. In the Name field, type a new name to identify the block. This name appears in the logic diagram and replaces the MUX heading in the Details dialog box.
  5. For MUX blocks with Enum Mode, select the enumeration set to use from the Units drop-down list.
    Note: This field is used for MUX blocks with Enum Mode only and is disabled for Boolean Mode. If you change the Units, the Input X - Mode(s) fields are cleared and must be configured.
  6. Click an Input X - Modes button. The Mode Selection dialog box appears.
  7. Select the value or values to use for the mode and click OK.
    Note: The Default value defines the input that is passed to the Present Value if the Mode value is not assigned to an input. If every member of the Mode Enum Set is not associated with an Input, you must define a Default input.
  8. Click Apply.
