A data bus system is disclosed, including a plurality of nodes coupled together by a daisy chain bus. Each node includes a first and a second bus connection, each having a first and second bidirectional terminal. An arbitration logic is coupled between the first and second bus connection. The node operates in an arbitration mode, during an arbitration time interval, in which the first bidirectional terminal in the first bus connection, and the second bidirectional terminal in the second bus connection are configured to be input terminals, and the second bidirectional terminal in the first bus connection and the first bidirectional terminal in the second bus connection are configured to be output terminals. Then the node operates in a bus access mode in which the first and second bidirectional terminals in the respective first and second bus connections, are both configured to be one of input and output terminals.
