1. A process for selectively authorizing the connection of external equipment to a data bus, by an exchange of data between an equipment set and the data bus via a communication interface, wherein:

  • detection information for an external equipment set is input to the data bus by way of a user interface;

    the detection information is transmitted to an authorization system connected with the data bus;

    detection information of the external equipment set is extracted from the data transmitted from the external equipment set via the communication interface to the data bus;

    based on detection information input from the data bus via the user interface, and on the detection information transmitted from the equipment, the authorization system checks whether a communication is to be established between the data bus and the equipment set to be selectively coupled, and the result of the check is made available as authorization information; and

    when the authorization information is positive, the authorization system permits communication to the equipment set, by means of the communication interface, whereby components linked to the data bus via the data bus exchange data with the external equipment.
