ABSTRACT:
A receiving node of a data transmission system receives data frames transmitted from a transmitting node through a transmission line. Each frame includes a node abnormality discrimination flag and a plurality of bits representing normality/abnormality of respective sensors and actuators which supplies information to be transmitted. On the basis of the node abnormality discrimination flag and the information supply means abnormality bits, the receiving node discriminates an occurrence of abnormality of the transmitting node from that of the information supply means, and the occurrences of the abnormality of the respective sensors and actuators from each other.
