Abstract

There is described a method for managing mobile operating devices, which are used to operate a machine within an assigned active area. Emergency stop outlets are triggered as a function of status information of an operating device and of the logon in an active area.

Claims

1. A method for managing a mobile operating device for operating each of a plurality of machines that are controlled by a controller, the method comprising:

establishing a wireless communication link between the operating device and the controller;

providing an RFID transponder on each machine, wherein the RFID transponder establishes an active area for the respective machine;

providing a restricted logon for the operating device within each active area via recognition of one of the RFID transponders by the operating device;

wherein the controller implements the following alternative steps in case of an error on the wireless communication link;

providing an emergency global stop of all of the machines if the error occurs while establishing the wireless communications link;

providing a local shutdown of only the respective machine if the error occurs after a logon of the operating device to the active area;

providing a global ramp-down of all of the machines according to a user-specified schedule if the error occurs while the operating device is logged off; and

providing a local ramp-down of the respective machine according to a user-specified schedule if the operating device leaves the active area for more than a specified duration without logging-off.

2. The method as claimed in claim 1, wherein an operating device function module with status information is provided in the controller for the operating device.

3. The method as claimed in claim 1, wherein an active area function module is provided in the controller to control the alternative steps for each active area.

4. The method as claimed in claim 2, wherein an active area function module is provided in the controller to control the alternative steps for each active area based on the status information.

5. The method as claimed in claim 1, wherein a first status information in the controller specifies whether the operating device is incorporated in or segregated from the controller, wherein “

incorporated”

means the wireless connection between the operating device and the controller is established, and ‘

segregated”

means the wireless connection is not established.

6. The method as claimed in claim 2, wherein a first status information specifies whether the respective operating device is incorporated in or segregated from the controller, wherein “

incorporated”

means the wireless connection between the operating device and the controller is established, and ‘

segregated”

means the wireless connection is not established.

7. The method as claimed in claim 3, wherein a first status information specifies whether the respective operating device is incorporated in or segregated from the controller, with the incorporation then being provided when a payload data transmission takes place between the controller and the relevant operating device wherein “

incorporated”

means the wireless connection between the operating device and the controller is established, and ‘

segregated”

means the wireless connection is not established.

8. The method as claimed in claim 4, wherein a first status information specifies whether the respective operating device is incorporated in or segregated from the controller, with the incorporation then being provided when a payload data transmission takes place between the controller and the relevant operating device wherein “

incorporated”

means the wireless connection between the operating device and the controller is established, and ‘

segregated”

means the wireless connection is not established.

9. The method as claimed in claim 5, wherein the operating device signals the incorporation of the operating device to a user.

10. The method as claimed in claim 6, wherein the operating device signals the incorporation of the operating device to a user.

11. The method as claimed in claim 5, wherein a second status information specifies whether the relevant operating device is logged-on in an active area.

12. The method as claimed in claim 6, wherein a second status information specifies whether the relevant operating device is logged-on in an active area.

13. The method as claimed in claim 5, wherein an immediate stopping of the assigned machines is triggered when a communication error of an incorporated operating device logged-on in an active area occurs.

14. The method as claimed in claim 6, wherein an immediate stopping of the assigned machines is triggered when a communication error of an incorporated operating device logged-on in an active area occurs.

15. The method as claimed in claim 5, wherein a defined stopping of the assigned machines takes place in an active area-independent fashion when a communication error of an incorporated operating device occurs, in accordance with the specifications of a user.

16. The method as claimed in claim 6, wherein a defined stopping of the assigned machines takes place in an active area-independent fashion when a communication error of an incorporated operating device occurs, in accordance with the specifications of a user.

17. A method for operating a plurality of machines from a wireless mobile operating device, the method comprising:

providing a controller that controls each of the machines;

providing a wireless communication link between the operating device and the controller;

providing an indication on the operating device when the operating device is incorporated with the controller, meaning that the wireless communication link is established;

defining an active area for each respective machine via a transponder on each machine, within which area a user can logon to the active area via the operating device to control the respective machine therein via the controller, wherein the operating device determines when it is within one of the active areas by communicating with and identifying the transponder; and

wherein the controller implements the following alternative steps in case of an error on the wireless communication link;

providing an emergency global stop of the plurality of machines if the error occurs while establishing the wireless communications link;

providing a local shutdown of only the respective machine if the error occurs after a logon of the operating device to the active area;

providing a global ramp-down of the plurality of machines according to a user-specified schedule if the error occurs while the operating device is logged off; and

providing a local ramp-down of the respective machine according to a user-specified schedule if the operating device leaves the active area for more than a specified duration without logging-off.
