In a method for increasing the data rate of a bus system in which at least at times an exclusive, collision-free access of a subscriber station to a bus line of the bus system is ensured, a subscriber station for the bus system includes a communication control device for evaluating a message that was received by at least one further subscriber station of the bus system via the bus system, the communication control device including at least two RX protocol machines that are set up to use different bit timing parameter data sets in order to evaluate whether the received message is valid, the at least two RX protocol machines each being assigned a register to which the associated RX protocol machine is designed to write the result of its evaluation of the received message.
