PURPOSE:To improve the reliability of set value information by transmitting set value item number information after converting it to a fixed mark code at a set value information transmission and verifying the fixed mark of a set value item number as a set value information update condition in the reception side. CONSTITUTION:Set value control information includes item number information and set value information, and item number information is converted to the fixed mark code through an input circuit 1 and is inputted to a scanner 3. Set value information is inputted to the scanner 3 through the circuit 1. They are converted to bit serial signals successively by a transmission code converter 4 and are modulated by a modulator 5 and are transmitted. A received signal is demodulated by a demodulator 6 and is converted to a bit parallel/word serial signal by a reception code converter 7, and set value item number information and set value information are stored in an individual memory 9 and a set value information memory 11 respectively by a distributor DIST8. Information from the memory 9 is verified with respect to the fixed mark by a means 10 to output a set value item signal. With respect to the memory 11, the output of the DIST8 is stored in a memory 15 if coincidence between the output address of the DIST 8 and the address of a setting part 12 is detected by a coincidence detecting circuit 13. |
