Set screen controls to show the hardware value
By default, screen controls show the value of the parameter the control is mapped to. Alternatively, they can show the value of the hardware control assigned to the screen control; for example, when the screen control is assigned to a foot pedal or when the screen control is mapped to multiple parameters.
Set a screen control to show the hardware value
Select the screen control in the workspace.
In the Screen Control Inspector, click the Attributes tab.
Select the Show Input Value checkbox.
