    摘要: A duplex communication control device for a communication system comprising a plurality of stations which communicate data therebetween, wherein the stations are connected to a duplexed communication network and each station comprises a bus status list storing information indicating whether the station can communicate over a first or second communication line of the network; a token generating means which carries the newest bus status information on a token frame and transmits the token frame over the communication lines; a list updating means which receives the token frame transmitted over the lines and updates the contents of its own bus status list according to the bus status information carried on the token frame; and a transmission-reception means which selects one or both of the lines according to the bus status list for communication.
