Control method for communications system

摘要

The method involves sending a communication frame, which comprises a transmitting data sequence (4), by one of a number of connected network nodes in the transmission path, which have a communication control mechanism and are joined to a bus conductor. A network node in the receiving area codes a received communication frame, and stores it as reception data. If no errors are detected in the received communication frame, the stored reception data is sent back to the transmitting network node without modification, as a back message signal.
