2. SIL Integrity
Systematic safety integrity SIL3-capable software
Integrity against "random, dangerous
hardware errors"
(Type B components)
Single channel operation (HFT = 0, e.g. 1v1); SIL2
Two channel operation SIL3: to IEC 61508-6 Annex D
must determine a β-factor for the two channel (redun-
dant) application, in order to incorporate the 'Common
Cause Failure Probability'.
