Abstract: A method for the access management of a wind turbine controller of a wind turbine with an operating software. The method comprises receiving a user identification with one of several user interfaces and assigning the user identification or a portion of the user identification to an access group. One or several authorization groups of an overall number of authorization groups is allocated to the access group, and one or several output value storage locations and/or input value storage locations are allocated to each authorization group. The method further encompasses allowing an access from the user interface to all output value storage locations and/or input value storage locations that are allocated to the assigned access group via the authorization groups. The disclosure further relates to a computer product, a wind turbine controller, and a wind turbine with a wind turbine controller.
