Authors describe the solutions of safety industrial Ethernet with orientation to safety-related industrial control systems. Nowadays the numbers of safety solutions of industrial Ethernet are increasing (e. g. CIP Safety, ProfiSafe, Safety Interbus). Bernecker & Rainer is coming with the new solution - Open Safety, which was developed for technology Ethernet PowerLink (EPL), but open platform is compatible with the other types of industrial Ethernet too, e. g. Sercos, Ethernet/IP, Modbus, and Profinet. Mainly part of paper the safety analyses of Open Safety frame with orientation to safety codes used in two sub-frames are mentioned. Practical part is orientated to model realisation via Matlab, Simulink with the use of safety codes with possibility to demonstrate the detection capability of cyclic CRC codes dependence on characteristics of communications channel and generator polynomial selection.
