Collector wire network for communication of locally fixed systems parts with at least one variable-location system part

A collector wire network for communicating locally fixed system parts having at least one variable-location system part, wherein data transmission devices are each assigned a reception range, where the reception range is mapped onto a section that results from a length of a collector wire segment plus a first overlap length and a second overlap length, the data transmission device connected to the respective collector wire segment is configured such that a level of the data signal transmitted thereby is matched to a respective reception range such that, because of attenuation of the level, caused by line damping along the first and second conductors and the coupling elements, the level in a receiving device of a variable-location system part which is located outside the reception range no longer recognized as a valid signal.
