Data transmission system with bus failure recovery

A data transmission system for implementing data transmission among a plurality of nodes mutually connected by a cable serving as a bus, said system comprising:

• means for performing a first process for initializing a control process on said nodes to said bus in accordance with a change in an electrical connection of said bus, a second process of detecting a connection topology of said nodes, and a third process for identifying each node to be connected to said bus;
• forbidden connection detecting means for detecting if the number of said nodes connected to said bus exceeds a specific number;
• and
• handling means for executing handling in accordance with a result of detection by said forbidden connection detecting means.

• forbidden connection detecting means for detecting if connection paths on said bus contain any connection path having a number of connected nodes, including one terminal node and another terminal node, in which said number exceeds a specific number;
• and
• handling means for executing handling in accordance with a result of detection by said forbidden connection detecting means.
