Abstract

　通信装置が伝送路に直列に接続された場合でも、各通信装置に接続された機器が同期し、通信周期を短くすることができる通信装置・方法を提供する。 　第２通信装置（２）に記憶装置を経由しない中継路（２６０）および折り返し経路（２６１）と、それらの経路切り替えスイッチ（２５０）を備え、第１通信装置（１）が伝送路（５）から折り返し経路（２６１）の切り替えを指示して伝送路遅延時間を計測して第２通信装置（２）に通知し、通信周期毎に第１通信装置の基準タイムを送信し、第２通信装置は、該伝送路遅延時間と該基準タイムで、自己の基準タイムを補正する。 　また、第１通信装置（１）は同期通信中に新たな第２通信装置（２）を発見したときも、通信周期の残り時間を用いて伝送路遅延計測を行う。 　さらに、第１通信装置、第２通信装置は、フレーム開始信号を検出して転送遅延を短くする手段を備える。
