    For more complex installation systems the use of the WAGO LON bus system results in a notable reduction of commitment to be put into projecting, wiring, start-up and trouble-shooting. A dramatic cost reduction can be achieved com- pared to other decentral control systems, such as, for example the European Installation Bus (EIB).
