Abstract

PURPOSE:To always securing several data transmission devices which are available for transmission and to elevate the transmission efficiency, by connecting many data transmission devices in a loop by the time sharing multichannel, and concentrically controlling the right for using a frame of the data transmission device. CONSTITUTION:Many data transmission devices (SST) 2-N are connected in a loop together with the central control unit (MST) 1 which concentrically controls the whole system, by the time sharing multichannel L. MST 1 makes a frame consisting of a frame synchronous bit F, a control information part CI, and a data part I by sharing the transmission line L by timing, and has both the function of allocating the right for using each frame as mentioned above most suitably depending on the priority degree and the function of monitoring the working status of these frames. SSTs 2-N have a function of writing a transmission data in the allocated frame and taking in a data which has been transmitted to themselves.
