Abstract

A power tool having a digital control unit is provided, an interface of the digital control unit being switchable between standard operation and communication operation. In communication operation, operating data of the power tool are able to be transmitted via the interface.

Claims

1. A power tool, comprising:

a digital control unit,

wherein an interface of the digital control unit is switchable between standard operation and communication operation, and operating data of the power tool are transmittable via the interface during the communication operation.

2. The power tool according to claim 1, wherein the interface is switchable periodically between the standard operation and the communication operation, and the operating data are outputtable via the interface.

3. The power tool according to claim 1, wherein the interface is an interface between an electrical energy store device and the digital control unit.

4. The power tool according to claim 3, wherein the operating data are outputtable via one of supply lines and code lines of the interface.

5. The power tool according to claim 4, wherein the operating data are transmittable by a modulation system via the supply lines of the interface.

6. The power tool according to claim 1, wherein the interface is formed from control lines of a light-emitting diode of the power tool.

7. The power tool according to claim 1, wherein the operating data are storable in the standard operation of the power tool, by a storage device.

8. The power tool according to claim 7, wherein the stored operating data of the storage device are outputtable by the power tool by a transmission device.

9. The power tool according to claim 1, further comprising a data acquisition device for acquiring the transmitted operating data.

10. The power tool according to claim 9, wherein the data acquisition device is situated one of inside and outside the power tool.

11. A data acquisition device, which cooperates with the power tool according to claim 1, in order to acquire the operating data of the power tool.

12. The data acquisition device according to claim 11, wherein the data acquisition device is developed as an adapter, which is attachable to the power tool.

13. A method for operating a power tool comprising a digital control unit, the method comprising:

switching over an interface of the digital control unit between standard operation and communication operation,

wherein in the communication operation, operating data are transmitted from the power tool via the interface.

14. The method according to claim 13, wherein the switching over between the standard operation and the communication operation takes place periodically.

15. The method according to claim 13, further comprising storing the operating data by a storage device.

16. A computer program product having program code stored on a non-transitory computer-readable medium, wherein the program code instructs a programmable computer system to perform the method according to claim 13.
