Abstract

PURPOSE:To realize a simultaneous control of optional plural numbers of slave stations, by carrying out the transmission and reception of the simultaneous control frame provided with the item word corresponding to each slave station with a discontinuation of the polling cycle. CONSTITUTION:At control stations A-N to be monitored, the simultaneous control signal is decided by the signal of word 22 of the simultaneous control station number code as well as the signal of word 21 of the simultaneous control code of the simultaneous control signal sent from monitor station S. After this, either one of signals (word of pulse position) 23-27 of the simultaneous control item of the self-office is received to actuate its own simultaneous control unit. Accordingly, the plural numbers of stations of the subject for the simultaneous control can be selected freely by providing the information showing whether the simultaneous item exists or not at each item position of signals 23-27.
