(2) It’s possible to draw the Logic Diagram of the SIF (one by one).

(3) It’s possible to show Logic Diagrams of the SIFs in the Report.

(4) Option to make an analysis of the SIF behavior by changing main parameters (quick generation of 12 PFDavg values in the same SIF).

(5) Example “SIL Verification Report” (Word template plus 3 annexes)

(6) Factor to multiply PFD/PFH/STR to calculate SIFs which are bypassed and degraded for online tests, etc.

(7) Calculation of PFDavg when making online proof tests (e.g.: PST online and FST offline). Equations are based on ISA TR84.00.03.

(8) New macro to generate up to 10 lists of the selected SIFs in order to compare different configurations, for example by introducing different correction factors of the main parameters (failure rates, Cpt, TI, LT, Beta, MTTRdd, MTTRs).
