You can animate the PickDisabled property of an object to control when a pick action menu is available for the object.
The expression for the PickDisabled property needs to equal TRUE for the pick action menu to be available, and it has to equal FALSE for the pick action menu to be unavailable.
You can enter True or False as the expression, or you can use a more complex expression that returns a True or False answer. For example, if a Mimic object is to provide access to a pick action menu only when a specific 1 bit digital point is in state 0, you would need to enter the following as the expression for the PickDisabled property of the Mimic object:
"<path and name of point>.CurrentState" = 0
Where <path and name of point> is the location and name of the point in the database. Do not enter the angle brackets < >.
CurrentState is the name of the point property that is used to animate the Mimic object's PickDisabled property.
The final part of the expression defines that if the CurrentState value of the point is 0, then the result of the expression is TRUE and so the pick action menu is available. If the CurrentState is not 0, the result of the expression is FALSE and the pick action menu is unavailable.
