8.3. Industrial Profile (IEC 61508)

The industrial profile supports a broad range of applications that work according to IEC 61508. This safety domain can be used and tailored also for ISO 13849, IEC/EN 62061, EN 50126/50128, or other standards based on Safety Integrity Level (SIL) definitions.

8.3.1. Industrial Project Template (IEC 61508)

The default industrial profile project template consist of the following package structure:

  • Preliminary Hazard Analysis

    This package supports the creation of Preliminary Hazard Analysis (PHA) and Hazard Logs. By default, no risk graph is defined to determine SIL/Performance Levels, but these are provided by more specific project templates derived from this template (e.g. ISO 13849).

  • Safety Requirements

    The safety requirements hierarchy of functional, technical, HW/SW requirements can be modeled in this package together with the tracability to PHA and system design.

  • System Design

    System Design models are managed in this package. They can be created or imported as needed.

  • FTA Models

    All fault trees are managed in this package.

  • FMEA Worksheets

    This folder is meant to manage the Failure Mode Effect and Analysis worksheets.

  • FMEDA

    Worksheet support for the Failure Mode Effect and Diagnostic Analysis to compute e.g. the Safe Failure Fraction (SFF) and Diagnostic Coverage (DC).
