Subscriber station for a bus system and method for transmitting data in a bus system

A bus system, comprising:

• at least two sub-buses including a first sub-bus and a second sub-bus;
• at least one master subscriber station for the bus system, including:
• a first transceiver device for at least one of:
• sending a message to at least one slave subscriber station via the first sub-bus of the bus system, or receiving a message from the at least one slave subscriber station via the first sub-bus of the bus system;
• the at least one slave subscriber station being subordinate in terms of control to the master subscriber station;
• a second transceiver device for at least one of:
• sending a message to at least one other subscriber station via the second sub-bus of the bus system, or receiving a message from the least one other subscriber station via the second sub-bus of the bus system;
• a communication control device for creating messages to be sent via one of the first or second sub-buses of the bus system or for evaluating messages received from one of the first or second sub-buses of the bus system;
• and
• a linking device for linking a terminal of the first transceiver device to a terminal of the communication control device, for outputting a signal that was generated from the message received from the first sub-bus, and for linking a terminal of the second transceiver device to the terminal of the communication control device, for outputting a signal that was generated from the message received from the second sub-bus, so that only one signal is forwarded as a receive signal from the first and second transceiver devices to the terminal of the communication control device;
• and
• the at least one slave subscriber station that is subordinate in terms of control to the master subscriber station;
• and
• the at least one other subscriber station;
• wherein the at least one master subscriber station and the at least one slave subscriber station are connected to one another via at least the first sub-bus so that the at least one master subscriber station can communicate with the at least one slave subscriber station.

A method for transmitting data in a bus system, the method comprising:

• using at least one first transceiver device to send a message to and to receive a message from at least one slave subscriber station that is subordinate in terms of control to a at least one master subscriber station, via a first sub-bus, wherein the bus system is configured so that the at least one master subscriber station is connected to at least two sub-buses to each of which at least one subscriber station is connected, the at least one master subscriber station having a communication control device for creating the message to be sent or for evaluating a message received from one of the sub-buses, and the at least one master subscriber station in addition having the at least one first transceiver device for the first sub-bus and a second transceiver device for a second sub-bus;
• using the second transceiver device to send a message to and to receive a message from at least one other subscriber station, via the second sub-bus;
• and
• using a linking device connected to the communication control device to link a terminal of the first transceiver device, at which a signal is outputted that was generated from the message received from the first sub-bus, and a terminal of the second transceiver device at which a signal is outputted that was generated from the message received from the second sub-bus, so that only one signal is forwarded, as received signal, to a terminal of the communication control device.
