1. A carrier-rail bus assembly comprising a number of n mechanically contiguous bus-circuit-plate sections (4) electrically connected via bus circuit paths (6), wherein the bus-circuit-plate sections (4) are installed next to each other in installation positions i (1≤i≤n) and each have k contacting elements (10) for being electrically contacted with an apparatus (5) inserted on a carrier rail (8) in a respective installation position of the installation positions i,
characterized in that
the carrier-rail bus assembly further comprises a plurality of distinct detection circuit paths (7), and
an electronic control unit (12) is disposed on a first bus-circuit-plate section in a first installation position i=1 of the installation positions i and each of the distinct detection circuit paths (7) leads from the first bus-circuit-plate section in the first installation position i=1 to a respective downstream bus-circuit-plate section of the bus-circuit-plate sections (4) such that the first bus-circuit-plate section in the first installation position i=1 is connected to each of the respective downstream bus-circuit-plate sections by a different one of the plurality of distinct detection circuit paths (7), the electronic control unit (12) detecting, by means of a respective one of the distinct detection circuit paths (7), whether the apparatus (5) is inserted in the respective installation position of the installation positions i in question, and the electronic control unit being configured such that the respective installation position of the installation positions i is allotted to a bus address (14), which is assigned to the apparatus (5) inserted on the carrier rail (8) on a respective bus-circuit-plate section of the bus-circuit-plate sections (4) in the respective installation position of the installment positions i.
