Binding Operator Interface Controls to Step Parameters

When you enable operator mode, LabVIEW SignalExpress limits the amount of interaction users can have with a project. However, you can create an operator interface that allows a user to adjust the values of certain step parameters when operator mode is enabled. You create an operator interface by adding controls to the Operator Interface view, and you enable those controls to adjust step parameter values by binding the controls to a specific parameter or set of parameters.

Note Note  You cannot bind text or label controls to step parameters. You can bind a single ring control to one parameter only.

Complete the following steps to bind an operator interface control to a step parameter.

  1. Select a control on the operator interface. Resizing handles and a small arrow icon () appear.
  2. Click the small arrow icon to display the Tasks window.
  3. In the Tasks window, click the Edit Bound Parameters link to display the Bound Parameters List dialog box. This dialog box binds the control to parameters of steps in the project.
Note Note  You also can display the Bound Parameters List dialog box from the Properties window. Display the Properties window, select a control on the operator interface, and select the Bound Parameters property that appears under Parameter Binding in the Properties window. Click the button that appears next to the value of Bound Parameters to display the Bound Parameters List dialog box.
  1. In the Bound Parameters List dialog box, click the Add button under the Members list to display the Bound Parameter Editor window, which displays a list of all the steps in the project.
  2. In the Bound Parameter Editor window, click the expand icon next to a step to display the parameters of the step to which you can bind the control.
  3. Select a parameter and click the OK button. The parameter appears in the Members list of the Bound Parameters List dialog box. The Properties list also updates to display properties of the parameter you select. Expand a property in the Properties list to edit the property. You also can use the Scale option to specify how changing the value of the control changes the value of the property. For example, if you specify a Multiplier of 2, incrementing the control value by 1 actually increments the property value by 2.
  4. (Optional) Repeat steps 4 through 6 to bind the control to additional parameters.
  5. Click the OK button to close the Bound Parameters List dialog box and bind the control to the parameter(s).
