Classification: CPC H | IPC H

Claim 14:
15. A method for a communication in a serial bus system, the method comprising the following steps:
counting, using a transmit signal analysis module, edges of a transmit signal that is to be transmitted on a bus of the bus system in order to exchange a message between subscriber stations of the bus system;
counting, using a receive signal analysis module, edges of a receive signal that is generated from a signal transmitted on the bus because of the transmit signal, in which bus states of the signal for the message in a first communications phase differ from bus states of the signal received in a second communications phase;
evaluating, using an evaluation module, a difference that results from a comparison of the edges counted by the transmit signal analysis module and the edges counted by the receive signal analysis module; and
signaling, using the evaluation module, in the event that a signal propagation time on the bus is greater than a bit time of the receive signal, whether an amount of the difference is less than or equal to a predefined value or whether the amount of the difference is greater than the predefined value, the predefined value being greater than zero.
