PROCESSING MACHINE WITH ACCESS CONTROL VIA COMPUTER NETWORK

摘要

A control device controlling a processing machine receives from an external source initial data which includes at least identification data identifying the source of the initial data. The control device transmits the identification data via a connection to a computer network to a computer that is part of a computer cluster and receives authorization data from the computer or from another computer of the computer cluster. The control device allows or denies the user access to the internal data of the control device depending on the authorization data.
