FB_BA_BaseStateMV

The function block FB_BAStateMV enables the display of states. Each referenced object is seen as state.
It is represented as multi-state object.

The state texts of this multi-state object are automatically the names of all commanded references.

The PresentValue is automatically the highest active state, or reference.

	Abstract The FB serves as a base (ABSTRACT) for providing described functionalities for inheriting FBs.
