The holdTime attribute specifies a minimum hold time for the button. The application will keep the button pressed for this length of time even if the operator releases the button sooner. The operator cannot press the button again until the hold time has expired. If a display containing the button is closed before the hold time has expired, the hold time will be reset, the button will be reset to state 0 and the value for state 0 will be written out.
The momentaryButton graphic object element contains this attribute.
