Abstract: A passenger transport system includes a bus system transferring data between a central control unit and a plurality of field devices. In a failure detection method, the field devices are configured in an unbranched chain configuration and the control unit transmits a test telegram to a first field device to start a monitoring cycle during which each field device receiving the test telegram forwards the test telegram to a next field device in the chain. During the monitoring cycle, the control unit monitors a communication between the field devices occurring via the bus system, in order to detect when a field device does not forward the test telegram. A data volume transmitted via the bus system during the failure detection method is significantly reduced in comparison to conventional failure tests such that failures can be recognized more quickly and/or simpler hardware and/or software can be used.
