    摘要: When an input data of a slave station makes any change, the slave station transmit a serial information (in serial data frame, FIG. 2) which is made by altering an information continuously transmitted from a master station into a serial information to be transmitted by interrupt, which serial information includes a start information (in start bit), interrupt information (in interrupt field), address information (in address field) of this slave station and data information (in data field) produced in this sub-station responding the change, and it is transmitted by the interrupt; therefore the master station can find the interrupt-transmitted serial information among many serial informations sent back thereto, and the slave station can immediately transmit the change to the master station without wasting time by waiting for one turn scanning of all the slave stations.

    摘要: In a loop-type optical fiber transmission system composed of a master apparatus (50) and a plurality of slave apparatus (54), when an intensity of incident light (6B, 6C, 6E) to a first slave apparatus (55) is insufficient, the first slave apparatus (55) sends a status signal (CS.sub.b) informing malfunction in the light intensity to the master apparatus (50), the master apparatus upon receipt of the status signal from the first slave apparatus (55) sends a command signal to increase an output light intensity of a second slave apparatus (54) which is positioned at the upper stream of the first slave apparatus (55), and thus the intensity of the output light from the second slave apparatus (54) is increased.
