Patent ID: 8344848

Claim:
Mobile control device, in particular a mobile hand-held device, for influencing at least a part of a controllable technical system, with at least one control element for issuing control commands by an operator, with at least one data interface for temporarily establishing an active data connection to a safe data transmission counter station assigned to the controllable technical system, with at least one standardized transmitter without any physically safe unequivocal point-to-point assignment to subscribers connected in between, with a first processor or detection circuit for encoding information, messages or signal states in a plurality of first data telegrams with a view to transmitting them across the active data connection to the safe data transmission counter station, wherein the mobile control device has a second processor or detection circuit and a reading unit, wherein the reading unit is suitable for reading, essentially simultaneously, several electronically readable tag codes when several log-in tags, zone tags or key tags are disposed within the detection range of the reading unit, wherein the second processor or detection circuit is configured to encode information, messages or signal states in the plurality of first data telegrams or in a plurality of second data telegrams, which first and optionally second data telegrams are intended for a transmission across the at least one data interface via the active connection to the safe data transmission counter station, wherein the first processor or detection circuit and the second processor or detection circuit are able to access the detected tag codes via the reading unit, and the first and/or optionally second data telegrams are generated, identified or sent under the influence of the detected tag codes, wherein at least one safety switch element which can be operated by the operator is provided for issuing safety critical control commands or authorizing or preventing potentially dangerous machine operations, wherein an operating state of the at least one safety switch element is repeatedly detected by the first processor or detection circuit and the second processor or detection circuit, wherein the detected operating state is encoded in the first and optionally second data telegrams, wherein the at least one safety switch element is of a multiple electric circuit design, in particular a two-circuit design, wherein several safety switch elements are provided, and wherein several, in particular two, safety switch elements each with identical functions are provided, the operating states of each of which are detected by the first processor or detection circuit and the second processor or detection circuit, wherein the detected operating states are logically linked by the first processor or detection circuit and the second processor or detection circuit to form an overall operating state depending on the function of the safety switch elements, and wherein the overall operating state is encoded in the first and optionally second data telegrams.
