PURPOSE:To simplify the system control through detection of the data transmission time by means of the word address and the frame address of the cyclic data transmission system which is provided together with the non-cyclic data transmission system. CONSTITUTION:The cyclic data transmission system is formed with transmitter A and receiver B; and the noncyclic data transmission system is formed with transmitter C and receiver D respectively. Thus both the frame and word addresses are always transferred to address reception part AR1 from transmitter A via address transmission part AS1. And the frame and word addresses which are transferred to processor CPUS of transmitter C from part AR1 are added to the data to be transmitted and then transmitted to receiver D via modulator/demodulator MODS. The same treatment is given also to receiver D, and the comparison is given with the addresses transmitted from transmitter C. In such way, the data transmission time is detected. |
