Classification: CPC H  G | IPC G  H

Claim 11:
12. A user station for a serial bus system, the user station comprising:
a communication control device configured to transmit a message to a bus of the bus system and/or to receive the message from the bus of the bus system;
a transceiver device configured to transmit the message on the bus and/or to receive messages from the bus; and
a frame screening unit connected to the communication control device and to the transceiver device, the frame screening unit including:
a screen block configured to generate a select signal that selects whether or not the communication control device of the user station is allowed to receive a reception signal that has been generated from a frame for the message that is serially received at that time from the bus; and
a reception signal selection block configured to screen the reception signal as a function of the select signal generated by the screen block, in a manner that the reception signal is not transmitted to the communication control device of the user station, the transceiver device being configured to, regardless of a bit rate of the frame of the message, generate during the transmission a first bus state for a first digital data state of the messages, and a second bus state for the second digital data state of the messages, in such a way that the second bus state overwrites the first bus state.
