PROBLEM TO BE SOLVED: To provide a transmission system and a transmission station capable of diagnosing a true abnormal part, using information related to the transmission of communication data, on the occurrence of abnormality ranging a plurality of transmission stations.SOLUTION: The transmission system, including a plurality of transmission stations connected through one transmission line, successively acquires a transmission right to transmit a frame to another transmission station, subsequent to a synchronous frame which is transmitted from a predetermined transmission station among the plurality of transmission stations at a predetermined transmission period. The transmission station includes an acquisition unit and a first storage unit. In synchronization with the transmission or the reception of a communication frame, the acquisition unit acquires first information related to the transmission or the reception of the communication frame. The first storage unit stores the first information and second information indicative of the acquisition date and time of the first information.SELECTED DRAWING: Figure 2 |
