    摘要： A data transmission system capable of ensuring proper operation even when any nodes-to-bus connection, which is not allowed by restrictions, is made. The system implements data transmission among a plurality of nodes mutually connected by a cable serving as a bus. The system includes a first process for initializing a control process on the nodes to the bus in accordance with a change in an electrical connection of the bus, a second process of detecting a connection topology of the nodes, and a third process for identifying each node to be connected to the bus. A forbidden connection detecting process is provided for detecting if there is a loop connection path of the nodes on the bus and handling operations are provided for executing handling in accordance with a result of detection by the forbidden connection detecting process.
