    摘要: A method and a device for exchanging data in messages between at least two stations connected by a bus system. The messages contain the data being transmitted by the stations over the bus system. Each message contains an identifier characterizing the data contained therein. Each station decides on the basis of the identifier whether to receive the message. The messages are controlled in time by a first station. The first station repeatedly transmits a reference message over the bus in at least one specifiable time interval. The time interval is subdivided into time windows of a specifiable length, the messages being transmitted in the time windows.

    摘要: A monitoring unit which is locally assigned to a bus controller of a user of a communication system, for monitoring and controlling the access to a data bus. Bus controller accesses data bus via a bus driver, and monitoring unit monitors and controls the access authorization of bus driver to data bus. In order to detect also permanent disturbances of bus controller and resulting errors of bus controller when accessing data bus monitoring unit has an arrangement for implementing a question-answer communication with bus controller and that it enables the bus controller to access data bus only if the question-answer communication establishes a proper functioning of bus controller.

    摘要: A control unit has two pairs of execution units, the two execution units of each pair redundantly processing the same program, and the output signals of each execution unit of one pair being compared to one another by a respective comparing unit, the respective comparing unit outputting an error signal when a difference in the output signals of the execution units of one pair occurs. A first pair of execution units are shut down when the error signal occurs for the first pair, and the control unit continues control operation using the second pair of execution units, and a pre-warning signal is output to the driver.

    摘要: An output stage, especially a switching output stage for switching inductive loads, having a plurality of individual output stages that are connected in parallel, which include degenerative transistors, in the degenerative path of which one respective Zener diode is present. The electric power during a switching-off process can be distributed in a particularly uniform manner to the individual output stages or transistors by disposing the Zener diodes near the associated transistors so that they are thermally coupled to the respectively associated transistor and their Zener voltage increases with increasing temperature.
