SIL Calculator Skill

Purpose

The SIL Calculator Skill determines Safety Integrity Levels for Safety Instrumented Functions and verifies SIF designs meet required risk reduction per IEC 61511.

Capabilities

SIL determination (risk graph, LOPA, risk matrix)
PFDavg calculations
Proof test interval optimization
Common cause failure analysis
Hardware fault tolerance verification
Diagnostic coverage assessment
Systematic capability evaluation
SIF verification calculations

Usage Guidelines

When to Use
