Data structure of selection of operating mode
To fulfill the safety function of the overall
selection of operating mode
system, a suitable activation system must be connected
to the safe outputs of the device. A suitable activation system is a safe control system that can process 1-of-n signals, for
example.
The failure probability of the overall system’s safety function can therefore be calculated as follows:
