Patent ID: 7848826

Claim:
A method for enabling an operation of automation components of a technical system via a mobile control and monitoring device, comprising: activating a first transponder device by at least one automation component, wherein the first transponder device is attached to the technical system; receiving a first identification from the first transponder device by the mobile control and monitoring device transmitted via a wireless communication connection; deactivating the communication connection between the mobile control and monitoring device and the automation components; while the communication connection is deactivated, sending a carrier signal by the mobile control and monitoring device; modulating the carrier signal by the first transponder device; receiving the modulated carrier signal by the mobile control and monitoring device; determining a first distance between the mobile control and monitoring device and the first transponder device; determining a radio-determined identification of the first transponder device based upon the modulated carrier signal; reactivating the communication connection between the mobile control and monitoring device and the automation components; and enabling an operation of the automation components via the mobile control and monitoring device, if the first distance is shorter than a predetermined first distance and if the radio-determined identification corresponds to the first identification.
