Abstract: An item of electrical equipment has a preprocessing device for digital measured values. The preprocessing device has an integrated circuit and an electronic memory chip that contains a configuration of a logic circuit. If a fault of the preprocessing device is identified, an operation of the preprocessing device is interrupted until the configuration of the logic circuit has been loaded from a configuration memory chip into the electronic memory chip. There is also described a method for rectifying device faults, such as by reloading a configuration of a logic circuit into an electronic memory chip of a preprocessing device.

Abstract: An electrical operating device includes measuring equipment for an electrical measured variable, and preprocessing equipment for digital measured values. The preprocessing equipment has an integrated circuit and an electronic memory component for configuring a logic circuit. A processor evaluates preprocessed measurement data and, on the basis of the evaluation, transmits data telegrams to other electrical operating devices. The preprocessing equipment calculates a respective checksum for a digital measured value, and the processor recognizes a malfunction from the measured value and the checksum of the measured value, and suppresses the evaluation and/or the transmission of the data telegrams in the event of a malfunction. There is also described a method for recognizing malfunctions.
