PROBLEM TO BE SOLVED: To provide a redundant communication system capable of maintaining a redundant network without using a plurality of controllers when a break in an assumed network or a bus abnormality occurs.SOLUTION: A domain UNIT-A includes: a CPU10, a first driver A1 corresponding to a system I; a second driver A2 corresponding to a system II; and an OR circuit 11 arranged so that an output section 13 side is connected to a receiving section RX of the CPU10. A transmitter TX of the first driver A1 of the domain UNIT-A and a transmitter TX of the second driver A2 of the domain UNIT-A are connected to a channel of the transmitter TX of the CPU10 of the domain UNIT-A, respectively.SELECTED DRAWING: Figure 1

    【課題】想定されるネットワークの断線やバス異常が発生した場合、複数のコントローラを使用すること無く冗長ネットワークを維持可能な冗長通信システムを提供する。【解決手段】ドメインUNIT−Aは、CPU10と、系統Iに対応する第1ドライバA1と、系統IIに対応する第2ドライバA2と、出力部13側がCPU10の受信部RXに接続されるように配置されるOR回路11とを含む。ドメインUNIT−Aの第1ドライバA1の送信部TXおよびドメインUNIT−Aの第2ドライバA2の送信部TXは、それぞれドメインUNIT−AのCPU10の送信部TXのチャネルに接続されている。【選択図】図1
