ARRANGEMENT WITH AN ACTUATOR

摘要

An arrangement with an actuator has a transmitting device for transmitting control telegrams with a control command for the actuator. At least two receiving devices receive the control telegrams and generate a control signal for the actuator. A decision device between the receiving devices and the actuator allows the actuator to implement the control signals with a release signal if the control signal is present from all or a minimum number of receiving devices. The transmission device transmits the control command to each receiving device with a receiver-specific control telegram that is provided with a respective control instruction that indicates the continuous telegram number of the respective transmitted control telegram in encrypted or non-encrypted form. The receiving devices accept a control telegram as valid if the control instruction indicates a telegram number that is expected by the receiver. The control signal is generated if the control telegram is valid.
