Code logic 1
For logic 0, make is for logic 0, for logic 0, break is for 1, and for logic 0, tL is for logic 0. By checking the received local selection code, own station address code, and t bit by bit using this method, it is possible to completely prevent errors in received data, incorrect selection due to malfunction of the microcomputer, and incorrect selection when the power is turned off. Although FIG. 1 shows a case where the station selection code is 6 bits, essentially any number of bits may be used.

に作動する効果かある。Effects of the Invention As explained above, according to the present invention, the received station selection code is not processed inside the microcomputer, thereby preventing erroneous selection due to microcomputer runaway, etc. Since the selection code is checked bit by bit, erroneous selection will not occur even if the relay driver circuit fails, and since the check circuit itself is composed of a relay circuit, voltage and VfT will not occur. Since that contact is always open, there is no possibility of incorrect selection. In other words, this circuit has the effect of operating safely against all kinds of obstacles.
