The objects (TOR/door) of a plant or technical procedure are represented on screen. To create the user program the programmer assigns to each represented object at least one event (Closed, open) and associated behaviour (stop motor) to declare the reactions of the automation machine to events. The objects are e.g. images of real mechanical, electromechanical or other components of the plant, represented as a graphic symbol or in form of construction or tabular structure. Events and behaviour are assigned by selection of presented text, filling out table or form or by using program language.
