摘要： The use of radio technology for transmission of EMERGENCY-OFF, START-, STOP- and process and confirmation signals from industrial processing machines, such as numerically controlled machine tools and robots, by radio is described. There is no need for any additional safety measures for the START and process signals by means of a confirmation signal, provided the control functions satisfy appropriate safety requirements. To this end, safety-relevant signals are physically detected on at least two channels at the transmitter end, the detected data are logically transmitted by at least two channels using a safety technique by radio to a receiver end, and the received data are likewise physically processed and monitored on at least two channels at the receiver end. In addition to the safety-related signal data, additional protection data are produced for monitoring purposes and are used at the receiver end for monitoring by checking the plausibility of a redundant value for data protection and by cross-comparison of the evaluation results, etc.
