ABSTRACT:
A multiplex data communication system including a number of communication nodes interconnected through a transmission path, each of which includes a data transmitting/receiving circuit providing a reception signal representative of normal data reception from another communication node and a transmission signal representative of normal data transmission therefrom, and a data operation circuit for controlling an electronic equipment unit associated with each communication node based on the data from the other communication node and generating the data relating to each communication node which is transmitted by the data transmitting/receiving circuit, the data operation circuit making a judgement of normality of a data communication function of each communication node based on at least one of the data reception signal and data transmission signal.
