PURPOSE:To quicken the transfer speed to a specific group by looking in periodically all information such as fault information and also braking in the information of a specific group in all the information to attain the information forming one information based on the plural information. CONSTITUTION:In case of looking-in, three sets of information of outputs F0- F2 from a 3-bit counter 13 are decoded 14, expanded into 8 sets of information C0-C7, carry information CA of the counter 13 is inputted to a clock terminal of a 4-bit counter 15, decoded 17 via a selector 16 and expanded into information of G0-G15, each gate is controlled by the gate information of C0-C7 and G0- G15 to loop in input information A000-A127 sequentially. In case of brake-in, an input information group A015 is generated, a counter 13 is reset, an output E0 of the selector 16 is brought into H level and E1-E3 are into L level, an output G1 of the decoder 17 is brought into H level, the state of the counter 15 is neglected, the scanning of the information A008-A015 is started before the state of loop-in comes so as to improve the transfer efficiency. |
