Abstract
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.
Claims14
A method for operating a processing machine controlled by a control device, comprising:
- receiving with the control device directly from a user of the processing machine a user identification and an associated password via an input device assigned to the control device,
- transmitting with the control device the user identification and the associated password to a computer of a computer cluster which has a connection to a computer network,
- receiving with the control device user-specific authorization data from the computer or from another computer of the computer cluster,
- checking with the control device whether the user-specific authorization data allows access to internal data of the control device, and
- depending on a result of the checking, causing the control device to allow or deny the user access to the internal data of the control device.
A system program embodied in a non-transitory medium and comprising machine-readable machine code, which when read into memory of a control device of a processing machine and directly executed by the control device, causes the control device of the processing machine to:
- receive directly from a user of the processing machine a user identification and an associated password via an input device assigned to the control device,
- transmit the user identification and the associated password to a computer of a computer cluster which has a connection to a computer network,
- receive user-specific authorization data from the computer or from another computer of the computer cluster,
- check with the control device whether the user-specific authorization data allows access to internal data of the control device, and
- depending on a result of the check, allow or deny the user access to the internal data of the control device.
