Clearly structured screen forms are provided in SINUMERIK Operate to assist with the commissioning of Safety Integrated functions. Safety status information such as, for example, the name of the currently active Safety Integrated function, is transferred to the CNC via the safety info channel (SIC). The NCK and drive can exchange signals in the opposite direction via the safety control channel (SCC) for the purpose of conducting the safe brake test, for example. This solution significantly reduces the wiring outlay for the machine manufacturer.
