Abstract: A field device and method for parameterizing a field device via a parameter, wherein to provide validation, a first checking characteristic is calculated by the field device based on the parameter and a device ID stored, where the first checking characteristic is transferred to an engineering system, the parameter to be validated and the device ID are additionally transferred to the engineering system and are output on a display, where to confirm correct parameterization, a user can input the read first checking characteristic at an operating unit of the engineering system, which first checking characteristic is then transferred back to the field device, where the received checking characteristic is compared with the calculated checking characteristic to validate the parameter such that external calculations of checking characteristics are advantageously unrequired and relation of the validation to the correct field device is ensured.

Abstract: A method and apparatus for parameterizing a device with parameters from a parameter list, wherein in an event of a match occurring between an external parameter token calculated externally based on the parameter list, and an internal parameter token calculated internally by the device to be parameterized based on the parameter list, an external device token input into the device is compared with an internal device token, which is calculated internally by the device to be parameterized based on a device ID for the device and the internal parameter token to validate the parameter list such that fast and reliable parameterization of a device, particularly a safety critical device, which is provided in an industrial installation or a vehicle, is achieved.
