PURPOSE:To prevent incapability of all slave stations owing to a fault of partial transmission circuit, by resetting forcibly a selection signal of the slave station in terms of a fault occurs to the transmission circuit of a slave station pluse nonslection of the relevant slave station and nonselection of machinery. CONSTITUTION:In terms of the faults 10A and 10B exist at the transmission circuit of a slave station plus nonselection of the relevant slave station and nonselection of machinery, the end of selection is reset for the relevant slave station of the selection end memory circuit 17 by the selection end signal resetting circuit 36. With this reset output the slave station selection holding signal 29 is reset, and the slave station selection signal is released for the slave station having a fault on its transmission circuit. Thus a selection control is possible for the normal slave stations of other transmission circuits. |
