Abstract

An arrangement with a superordinated control unit and at least one intelligent field device connectable with the control unit, wherein associated with the control unit is at least one interface with a connection element for accommodating a corresponding connection counterpart. The connection counterpart is associable with an interface module, wherein associated with the interface module is a software protection system securing accessing of the field device. The interface module permits communication between the corresponding field device and the superordinated control unit, wherein associated with the superordinated control unit is a software-protected processing program for the field device, and wherein the processing program is started or enabled via the software protection system, when the connection counterpart of the interface module of the field device is connected with the connection element of the control unit.
