Safety Function Calculations
The GuardLink system typically consists of multiple taps and input devices.
When calculating the Performance Level or the safety integrity level, the safety
function must only consider the input device, the associated tap, the DG and
EM safety relays, and the output devices driven by the safety relays.
shows an example safety system to help demonstrate the process of determining
the Performance Level.
