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”.
