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.
A method for parameterizing a safety-critical device with parameters from a first parameter list which ensures parameterization and increases a speed at which the safety-critical device becomes parameterized, comprising:
A parameterizable safety-critical device which is configured to, based on a first parameter list read out from an external data carrier, internally calculate an internal parameter token which is output by the safety-critical device, and compare an externally calculated device token, which is then input into the safety-critical device, with an internal device token calculated based on the calculated internal parameter token and a device ID of the safety-critical device to validate the first parameter list such that parameterization of the safety-critical device is ensured and a speed at which the safety-critical device becomes parameterized is increased;
A parameterizing apparatus for parameterizing a safety-critical device in a manner which ensures parameterization occurs and which increases a speed at which the device becomes parameterized, wherein the parameterizing apparatus, based on a stored first parameter list, is configured to calculate an external parameter token and an external device token of the safety-critical device which is to be parameterized, wherein the external device token calculated externally by the parameterizing apparatus, in an event of a match between the external parameter token and an internal parameter token calculated internally by the safety-critical device which is to be parameterized, based on the first parameter list, is input into the safety-critical device which is to be parameterized to validate the first parameter list to ensure the parameterization occurs and to ensure the speed at which the safety-critical device becomes parameterized is increased;
