Arrangement with a superordinated control unit and at least one intelligent field device connectable with the control unit

摘要

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.

1. An arrangement with a superordinated control unit and at least one intelligent field device connectable with said control unit, wherein:
associated with said control unit is at least one interface with a connection element for accommodating a corresponding connection counterpart; said connection counterpart is associable with an interface module; associated with said interface module is a software protection system securing accessing of said at least one intelligent field device; said interface module permits communication between said at least one intelligent corresponding field device and said superordinated control unit, associated with said superordinated control unit is a software-protected processing program for said at least one intelligent field device; said processing program is started or enabled via said software protection system, when said connection counterpart of said interface module of said at least one intelligent field device is connected with said connection element of said control unit; in case of a plurality of said at least one intelligent field devices connectable with said control unit said processing program has a plurality of instances; each instance of said processing program is, via said corresponding software protection system, uniquely associated with one of said at least one intelligent field devices; and the individual instances of the processing program are secured via a distinct software protection, which is unlocked virtually as soon as the corresponding field device is connected with the control unit via the interface module.
