Abstract
There is described a method to operate a mobile operating device and a mobile operating device, with which machines within of effective ranges which are spanned by RFID transponders can be operated wirelessly. A safety module is provided in the operating device, with which both measured values assigned to the RFID transponders and also reference values of two reference transponders simulated in the operating device are checked in order to ensure the correct measurement and further processing in this way.

13. A method for using a mobile operating device to operate at least one machine in a safety-relevant manner in a plant, comprising:
-
providing the mobile operating device having a read device for receiving radio signals and an evaluation unit for evaluation of the radio signals; operating the machine within an effective range assigned to the machine, which is delimited by one or more RFID transponders; receiving the radio signals of an RFID transponder located in the receive zone of the read device by the read device; receiving the radio signals by the evaluation unit; determining an identification number of this RFID transponder by the evaluation unit based upon the received radio signals; determining a distance of the RFID transponder to the operating by the evaluation unit based upon the received radio signals; forwarding the data to a safety module in the operating device by the evaluation unit; receiving from at least one reference transponder its identification number and distance at predetermined intervals by the safety module via the transmission chain read device, evaluation unit and safety module; and checking as to whether the data of the reference transponder as regards the identification number and the distance as well as the predetermined intervals, is being received as expected by the safety module. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A mobile operating device with which at least one machine in a plant can be operated in a safety-relevant manner, comprising:
-
a read device for receiving the radio signals sent out by RFID transponders in the plant; an effective range assigned to the machine which is delimited by one or more RFID transponders, wherein an operation is provided within the effective range; and an evaluation unit for evaluation of these radio signals and for determining an identification number and the distance of the respective RFID transponder to the operating device from the radio signals for this received by the read device, wherein the evaluation unit has a safety module connected downstream from it which is used for checking the correct function of the operating device as regards transmission and evaluation of the received radio signals in the read device—
evaluation unit—
safety module transmission chain, and wherein a check is provided in the safety module of reference values of at least one reference transponder simulated in the operating device, for which purpose a comparison of these reference values with corresponding expected values is provided in the safety module after the reference values have passed through the read device—
evaluation unit—
safety module transmission chain. - View Dependent Claims (25, 26, 27, 28, 29)
