<p>A method for removing failures in which multinodes (10, 11, 12) are connected to common bus lines (A, B, C), and one of the multinodes, a failure detecting node (12), detects the abnormality of the the multinodes and the bus lines, and using the bus line (C) as a controlling line, the node (12) sends out a potential through the controlling line (C) to change the statuses of the bus lines. In the method, when the failure detecting node (12) detects a communication abnormality, it examines the bus connection current status (transmission mode), drives a controlling circuit (23) according to the kind of the detected communication abnormality and the detected transmission mode, and changes the status of the controlling line (C), thereby to make the nodes (12) change the bus lines.</p> |
