2. Safety Integrity
Systematic capability SC 3
Hardware safety integrity Single channel operation (HFT = 0, e.g. 1oo1): SIL 2.
Two channel operation SIL 3: to IEC 61508-6 Annex D
must determine a β-factor for the two channel
(redundant) application, in order to incorporate the
“Common Cause Failure Probability”.
