Claim 16:
17. A method for operating a wind turbine comprising a management system for controlling the wind turbine according to prescribed rules and a safety system, separate from the management system, for monitoring the wind turbine on the basis of operational characteristic values, wherein the safety system transfers the wind turbine to a safe plant state independently of the management system in response to safety-critical operational characteristic values violating safety parameters stored in the safety system, wherein in order to change at least one safety parameter of the safety parameters stored in the safety system a parameter block comprising the at least one safety parameter and at least two safety features is supplied to the safety system and accepted by the safety system for the monitoring only after a positive check on all of the safety features, wherein the check on at least one of the safety features requires comparison against check information available directly on the wind turbine and updating a parameter set used by the management system does not require a positive check of safety features available directly on the wind turbine.
