'Disable' Dynamic

The 'Disable' dynamic disables the object depending on the value of the Boolean variable assigned to the linked HMI tag or the value of a Boolean expression and the condition selected for the 'Disable When' property. Based on the value of the Boolean variable or the evaluation result of the Boolean expression and the selected condition, the object will be disabled when the variable is TRUE or FALSE or the expression is evaluated to TRUE or FALSE. If, for example, the 'Disable When' property is set to 'True', the object is disabled when the selected Boolean variable is TRUE.

When the condition is satisfied, the following applies to the object:

The object does not execute its actions when clicked.
In case of a check box or button, the linked variable is not affected when clicked.
The object has no keyboard focus.

Note
If an HMI object has a 'Read-only' dynamic assigned, the 'Disable' dynamic cannot be added to the object.
