For simplified projection of a cascaded fieldbus system which includes a first fieldbus with a plurality of first bus devices, a second fieldbus subordinate to the first fieldbus with a plurality of second bus devices and a third fieldbus subordinate to the second fieldbus with a plurality of third bus devices, an example embodiment of the invention provides that the second fieldbus is connected to the first fieldbus via a fieldbus access node device, and therefore bus devices of the second fieldbus are presented as virtual modules of the first fieldbus, and that a connection device, via which the third fieldbus is connected to the second fieldbus, is presented as a virtual fieldbus access node module of the first fieldbus, and therefore the remaining bus devices of the third fieldbus are presented as virtual modules of the first fieldbus. |
