A user station for a serial bus system and a method for transferring data with manipulation protection in a serial bus system. The user station includes a communication control device for creating messages which are to be transmitted serially via a bus line to at least one other user station of the bus system, and/or for reading the messages which have been received serially from the bus line. The communication control device is designed to use a predetermined communication rule for creating and/or reading messages, and the communication control device, for creating and/or reading messages, is designed to use at least one rule for creating and/or reading the messages, which is different from the predetermined communication rule, when a predetermined trigger occurs.

A method for operating an internal combustion engine, in whose exhaust gas system an exhaust gas treatment device is positioned, a reagent, which is possibly mixed with compressed air, being introduced into the exhaust gas system upstream from the exhaust gas treatment device, and a device for performing the method. The reagent is brought to a predefined reagent setpoint pressure using a reagent pump and subsequently metered using a reagent dosing valve. The reagent pressure existing upstream from the reagent dosing valve is detected. In the framework of a diagnosis, a time curve of the reagent setpoint pressure is predefined. The reagent pressure detected during the diagnosis is compared to at least one predefined threshold value. If the threshold value is exceeded, an error signal is provided. The corresponding diagnosis of a compressed air path may be provided alternatively or additionally to the diagnosis of the reagent path.

An apparatus (,) is described for determining the angle of a first rotatable body which coacts with two further rotatable bodies. The angle of the two further bodies can be measured, and the angle of the first body can be calculated therefrom. According to the present invention, means are provided with which simultaneous measurement of the angles of the two further bodies can be achieved. The accuracy of the determination of the angle of the first body is thereby improved.
