Disable objects

You can impose a level of security on your application with disable links. For example, you can disable touch sensitive objects based on operator access level or name. Or you can secure a button from tampering if no one is logged on.

A disabled state of ON means the touch functionality of the object or button is turned off and is not active as long as the expression is true.

Tip:Discrete expressions can contain analog tagnames. For example, TankLevel >= 75. In this example, when the value of the variable "TankLevel" is greater than or equal to 75, the object is disabled.

Create a disable 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 Miscellaneous section, select Disable.

   The Object Disabled -> Discrete Value dialog box appears.

   

4. In the Expression box, type the name of a discrete tag or expression that equates to a discrete value.

5. In the Disabled State section, do one of the following:

   • Select On to set the disabled state so that the object does not activate while the discrete tag or expression is true.

   • Select Off to remove the disabled state and enable the object to function while the discrete tag or expression is true.

6. Select OK.
