unit 3 4 and 5 the distance between control unit 3 and converter unit 2 and also the distance of the further control units 4 and 5 depends on the data transmission rate used by means of the field or can bus at low data transmission rates correspondingly large line lengths are possible whereas these are smaller at higher data transmission rates it is also possible to transmit specific data or signals to all control units 3 4 5 if these serve for instance the group control of said control units fig2 shows a further embodiment of a power and signal distribution system 1 according to the invention in this system eight control units 3 to 10 are connected in parallel with a converter unit 2 the connection between control units and converter unit is established by analogy with fig1 with a corresponding connection being provided between each control unit 3 to 10 and the converter unit 2 in the form of a cable 17 in particular for voltage and signal supply to be able to distribute the corresponding signals and or data in the embodiment according to fig2 the converter unit 2 comprises a so called router 18 said router substantially forms some kind of distributing device which forwards incoming data or signals to specific target networks or in the present case to control units this process being called routing moreover the cable connection 12 in fig2 is built up by analogy with fig1 and the values regarding voltage distance or the like are also like those of fig1 it should additionally be noted that like parts are provided.
