Abstract

PURPOSE:To detect state change information on a subordinate station at a high speed, by transferring transfer information, sent out of every subordinate station, together with added flag timing information for reporting the occurrence of a state change to a master station, and detecting the flag at the master station. CONSTITUTION:Pieces of information inputted from individual input devices 1A-3A, 1B-3B, and 1C-3C are scanned with scanning periods and transmitted from subordinate stations A-C at remote points to a master station D through modulators 5A-5C. At this time, state change data from the respective individual input devices are detected to generate flag timing signals for the occurrence of state change to the transmitted information by scanners 4A-4C, and they are added to data timing signals to send the resulting signals to the master station. At the master station D, the pieces of data information from the subordinate stations are inputted to demodulators 6A-6C, and the pieces of flag timing information are detected by a flag detecting circuit 7. On the basis of the detection output of the circuit 7, a station selecting circuit 8 selects a corresponding station and subordinate station information having a state change is outputted through a data distributor 9 after the test and collation of individual output devices 10A-10C.
