Summary:PCT No. PCT/JP90/01724 Sec. 371 Date Jun. 24, 1992 Sec. 102(e) Date Jun. 24, 1992 PCT Filed Dec. 27, 1990 PCT Pub. No. WO91/10302 PCT Pub. Date Jul. 11, 1991.A data input control device for a serial controller wherein a plurality of nodes each having one or a plurality of sensors connected thereto are serially connected to each other with a main controller included therein, the main controller delivers a predetermined data frame signal at a period sufficiently shorter than the variation interval of data detected by the nodes, and each node serves to add to the data frame signal the data from sensors connected to the node. The main controller compares the sensor data contained in the data frame signal inputted thereinto for predetermined times on receipt of a data frame signal, and takes thereinto the sensor data as true data only when the results derived from the comparisons performed by the predetermined times coincide with each other. Therefore, errors caused over the whole path through which the data outputted from the sensors are inputted into the main controller via the respective nodes can be detected.
