The invention relates to a participant station (10; 30; 50) for a bus system (1; 2) and to a method for increasing the data rate of a bus system (1; 2). The participant station (10; 30; 50; 60) comprises a device (15) for receiving a message (41, 42, 43) from at least one other participant station of the bus system (1; 2) via the bus system (1; 2). In the bus system (1; 2), an exclusive collision-free access of a participant station (10, 20, 30, 50) to a bus line (40) of the bus system (1; 2) is ensured at least temporarily. The participant station also comprises a testing device (12) for testing whether or not the received message (41; 42; 43) is specified for the participant station (10; 30; 50) and an error processing device (14) for processing errors of the received message (41; 42; 23) only when the test carried out by the testing device (12) indicates that the received message (41; 42; 43) is specified for the participant station (10; 30; 50).
