Abstract
A method and device for dual-channel transmission of safety-relevant sensor signals. In the method, two sensor signals to be monitored are generated parallel to one another by two sensors and the generated sensor signals are transmitted to a common evaluation unit via two separate, input-side transmission channels. Within the evaluation unit, the permissibility of the transmitted sensor signals is checked using prescribed calculation specifications that correspond to one another and an evaluation unit output signal representing permissibility or impermissibility is generated for each sensor signal. The individual processing steps of the two calculation specifications are decoupled by the evaluation unit for the two sensor signals and performed diversified within the evaluation unit. The generated output signals are output via two separate, output-side transmission channels.
