Abstract:
1. A method for the wireless transmission of a signal between a mobile operator unit and a base unit of a safety-critical device, the method comprising: categorizing one or more signals to be transmitted as safety-relevant control signals and one or more signals to be transmitted as non-critical communication signals; transmitting the safety-relevant control signals and the non-critical communication signals between the mobile operator unit and the base unit; differentiating the safety-relevant control signals and the non-critical communication signals using a control unit in the mobile operator unit, the base unit, or the mobile operator unit and the base unit; processing, using a safety module of the control unit, the safety-relevant control signals separately from processing, using a further module of the control unit, the non-critical communication signals; checking the safety-relevant control signals for error-free transmission; and transmitting the safety-relevant control signals via a defined contact assignment of connecting contacts of the control unit and transmitting the non-critical communication signals over a data bus, wherein the non-critical communication signals are transmitted without error safety checking.
