    Abstract: The present invention describes a method of allocating a defined user address to a safe bus user when connecting it to a field bus of a safe control system. The method comprises the step of sending out a first registration message from the safe bus user to an administration unit connected to the field bus. The first registration message contains a predetermined universal address. The method further comprises the step of sending out an address allocation message from the administration unit to the safe bus user, wherein the address allocation message contains the defined user address. Finally, the method comprises the step of storing the defined user address in a memory of the safe bus user.

    Abstract: The invention relates to a method for adjusting the data transmission rate in a fieldbus system (10) which is suitable to control safety-critical processes and which comprises at least one subscriber (12, 14) connected to a fieldbus (20), wherein in a first phase the subscriber/subscribers log on at a unit (30/central unit) centrally connected to the fieldbus with a first low data transmission rate. In a second phase the central unit (30) sets the data transmission rate at the subscriber/subscribers (12, 14) to a predetermined higher second value. In a third phase the subscriber/subscribers (12, 14) log on again at the central unit with a higher data transmission rate; and the central unit (30) shuts down the fieldbus (20) if it detects a deviation of the number of subscribers (12, 14) logged on in the first and the third phase. The invention also relates to a fieldbus system for implementing said method

    Abstract: The present invention relates to an apparatus for controlling safety-critical processes. The apparatus includes at least one safe control unit for controlling the safety-critical processes and at least two safe signal units which are connected via I/O channels to the safety-critical processes. The safe control unit and the safe signal units are connected to a common fieldbus. The safe signal units communicate with the safe control unit, but not with one another, when the apparatus is in the control mode. The safe signal units have an evaluator for evaluating a fault message which is broadcasted across the fieldbus, as well as a switching device which autonomously change the safety-critical process to a safe state when a fault message which is evaluated as being relevant occurs.

    Abstract: A system architecture uses at least two processors (2, 3), which jointly control a process and constantly compare their data with each other. A program complex which has been checked with respect to the possible errors, as well as a non-checked program complex, runs on one of the two processors (2). In order to rule out interference in the checked program complex by the non-checked one, the peripheral hardware (12) which interact with the checked program complex are provided with inhibit inputs (16), and the tested program complex, via the inhibit inputs (16), blocks the peripheral hardware (12) which are reserved for it before it gives up command to the non-checked program complex.

    Abstract: A safety switch for safety circuit arrangement has a control part for processing an input signal and at least one switching element with at least one active and one inactive switching state. The control part controls the switching element in order to generate an output signal dependent on the input signal at an output. In addition, the safety switch has a diagnostic function for identifying a functional fault.
