Abstract

For program creation, selected types of graphical objects ("State", "Action", "Transition", "Control Condition") and selected types of program attributes ("Basic", "Fault", "Automatic", "Manual", "Visible") are available. In the creation of an overall program, a plurality of graphical objects are brought into interrelation with one another in an application-dependent manner, and each graphical object of the overall program is assigned according to the invention a program attribute selected in an application-dependent manner. From the overall program, those graphical objects which have certain program attributes are combined in an application-dependent manner into activatable or rather deactivatable views representing subprograms.
