Claim 0:
1. A device for a serial bus system, comprising:
a transmit signal analysis module configured to count edges of a transmit signal that is to be sent on a bus of the bus system in order to exchange a message between subscriber stations of the bus system;
a receive signal analysis module configured to count edges of a receive signal which 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; and
an evaluation module configured to evaluation a difference that results from a comparison of edges counted by the transmit signal analysis module and edges counted by the receive signal analysis module, wherein, the evaluation module is configured to signal, 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, and wherein the predefined value is greater than zero.
