    Abstract: Unauthorized access to modules, especially modules in automation systems, is prevented by controlling access between modules and a central processing unit. At least one first device transmits an identifier to at least one of the central processing unit and a second device which evaluate(s) the identifier by comparison with at least one comparative identifier stored in the at least one of the central processing unit and the second device. Operation of the first device on the system is denied by the at least one of the central processing unit and the second device if the received identifier does not correspond to the comparative identifier.

    Abstract translation: 通过控制模块和中央处理单元之间的访问,可以防止未经授权访问模块,特别是自动化系统中的模块。 至少一个第一设备向中央处理单元和第二设备中的至少一个发送标识符,该第二设备通过与存储在中央处理单元和第二设备中的至少一个中的至少一个比较标识符进行比较来评估标识符 设备。 如果接收到的标识符不对应于比较标识符,则系统中的第一设备的操作被中央处理单元和第二设备中的至少一个拒绝。
