Abstract

PURPOSE:To make a circuit for specific intercepting office number collating, etc. unnecessary, by making a specific bit which is not used as an actual data significant, among data bits in an actual data word. CONSTITUTION:While an up-transmitting signal is sent to a master station 1 from the first slave station 11A, output terminals 31A-31M of the second -N-th slave stations 11B-11N maintain a data read inhibiting state in case when a flag F2 bit assigned to a specific bit of a part which is not used as an actual data among the up-transmitting signals of the slave station 11A is ''1''. However, when the flag F2 bit becomes ''0'' and also contents of the address bit part coincide with an address code set in advance to the output devices 31A-31M, this coincident output device releases the inhibiting state, and reads or updates a data of the up-transmitting signal of the slave station 11A. In this way, the data can be inputted through the corresponding output devices 31A- 31M by setting both the address and the flag F2 bit by the up-transmitting signal side.
