PROBLEM TO BE SOLVED: To provide a communication system capable of simplifying a system configuration resulting in a cost reduction.SOLUTION: When a master unit 10 determines that a communication with a follower unit 20 is not available based on a response/non-response to a communication signal transmitted to the follower unit 20 from a follower unit 20, the master unit 10 switches the output level for transmitting the communication signal to the follower unit 20 to an output level, which is different from the output level at a timing when non communication is made, during the communication with the follower unit 20 is available. When the output level which is switched by the master unit 10 continues for a certain period of time, the follower unit 20 resets.SELECTED DRAWING: Figure 1 【課題】システム構成を簡略化して更なるコスト低減を図ることができる通信システムを得ること。【解決手段】主装置１０は、従装置２０に送信した通信信号に対する従装置２０からの返信の有無により従装置２０との通信が不能と判断したとき、従装置２０へ通信信号を送信する出力レベルを、従装置２０との通信が可能な状態のときの通信を行わないタイミングの出力レベルとは異なる出力レベルに切り替え、従装置２０は、主装置１０で切り替えられた出力レベルが一定時間継続したときに従装置２０をリセットする。【選択図】図１
