Create a momentary button

Use the momentary push button object to create a button that starts a process or action by sending a value to the data source. Momentary push buttons send one value to the data source when pressed and another value when released.
A momentary push button can perform three types of actions:
  • Normally open
     sends a value of 1 when the button is pressed, and a value of 0 when the button is released.
  • Normally closed
     sends a value of 0 when the button is pressed, and a value of 1 when the button is released.
  • Value
     sends the values you assign to the button press and release actions.
To create a momentary push button:
  1. In the
    Graphics
    editor, select
    Objects
     >
    Push Button
     >
    Momentary,
     or click the momentary push button icon in the toolbox.
  2. Drag the mouse to position and draw a rectangle the general size and location you intend the button to be.
  3. Double-click the object to open the Momentary Push Button Properties dialog box.
  4. In the property tabs, specify how the button looks, the action to be initiated by the button, and its tags.
    TIP:
    Do not use push buttons for emergency stops. Emergency stop buttons must be hard-wired.
    If the button’s hold time is still in effect when the button is released, the second value is not sent until the hold time expires. You set up the hold time in the General tab.
