PROBLEM TO BE SOLVED: To allow a wiring path to branch off to two on the way even when a node to perform current data communication using a current signal and a node to perform voltage data communication using a voltage signal are made coexisted.SOLUTION: A voltage branching circuit 2 has a main voltage signal Vm used for voltage data communication separated from a main path M branch off to a branching voltage signal Va used for voltage data communication via a branching path A and a branching voltage signal Vb used for voltage data communication via a branching path B. A current loop circuit 3 has a main current signal Im used for current data communication separated from the main path M sequentially loop as a branching current signal Ia used for current data communication via the branching path A and a branching current signal Ib used for current data communication via the branching path B.SELECTED DRAWING: Figure 1 |
