The method involves receiving a control command by a controller (SR) over a wireless communication connection from a mobile operator device (B) for operating a machine e.g. robot. The command is executed by the controller, when the operator device is applied within an effective area (WB) based on transponder data received from radio frequency identification transponder (T) assigned to the area. The command is executed by the controller, when the device is present within the area and receives no valid transponder data, even after the controller obtains a characteristic signal. |
