A differential two wire - communication line communication system using

摘要

A communication system, the network, a plurality of nodes and a reducing means on. The netting has a main conductor and a plurality of branch lines, which branch off from the main line, wherein the main line and each of the branch lines in each case as a differential two wire - communication line are formed, which consists of a first communication line and a second communication line is. The plurality of nodes are provided with two or more branch conduits of the branch lines, in order to frame of data between the branch lines to communicate with one another. The reducing means is arranged at each node either a impedance of each of the first and second communication lines or an impedance between the first and second communication lines during a predetermined period of time to reduce the moment starts to a period of time, to which a node is a transmission of the frame of data to be transmitted has finished.
