Method for enabling the operation of automation components of a technical system via a mobile control and monitoring device

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;
• 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.

A control and monitoring device to operate automation components of a technical system, comprising:

• a receiver to receive a first identification of a first transponder device by the control and monitoring device, wherein the first transponder device is attached to the technical system, wherein the first transponder device is activated by the automation components, and wherein the first identification is transmitted via a wireless communication connection from the automation components to the control and monitoring device;
• a deactivator to deactivate the communication connection between the control and monitoring device and the automation components;
• a transmitter to send a carrier signal;
• a receiver to receive the carrier signal modulated by the first transponder device;
• a determining device to determine a first distance to the first transponder device and a first radio-determined identification of the first transponder device from the modulated carrier signal;
• a reactivating device to reactivate the communication connection between the control and monitoring device and the automation components;
• and
• an enabling device to enable the operation of the automation components via the control and monitoring device if the first distance is shorter than a predetermined first distance and if the radio-determined first identification corresponds to the first identification.

A method to enable an operation of automation components of a technical system via a mobile control and monitoring device, comprising:

• receiving a first message from the control and monitoring device to request an operation of the automation components, wherein the first message is transmitted via a wireless communication connection from the control and monitoring device to the automation components;
• transmitting a first identification from a first transponder device to the control and monitoring device, wherein the first transponder device is attached to the technical system;
• activating the first transponder device;
• deactivating the wireless communication connection;
• reactivating the wireless communication connection after an expiry of a predetermined time and deactivation of the first transponder device;
• and
• enabling of the operation of the automation components if an enabling signal is received by the control and monitoring device.
