You can design operator input touch links to change the value of discrete tags from one state to another. For example to turn a pump on or off, use discrete links.

Create a discrete input link

  1. Select the object you want to apply the animation to.

  2. On the Draw menu, in the Mode group, select Animate.

    Alternatively, right-click the object and then select Animation Links.

    The Animation Links window appears.

  3. In the Touch Links area, under User Inputs, select Discrete.

    The Input -> Discrete Tagname dialog box appears.

    Input: Discrete Tagname dialog

  4. In the Tagname box, type the name of a discrete tag.

  5. Optionally, in the Key Equivalent area, assign a key equivalent to the link. For more information, see Create keyboard shortcuts.

  6. Configure the discrete input details. Do the following:

    • In the Msg to User box, type the message to appear in the Input dialog box.

    • In the Set Prompt and Reset Prompt boxes, type the messages to appear on the buttons the operator will select to turn the discrete value on and off.

    • In the On Message and Off Message boxes, type the messages to appear in the text field associated with the object when the value is on or off.

  7. Select the Input Only checkbox to prevent the input from appearing in a text field associated with the object.

  8. Select OK.
