Functional Safety
Functional safety ensures hazards in industrial fields are eliminated or reduced through systematic design. The process involves:
- Requirement: Defining safety function and integrity requirements.
- Safety Design: Utilizing devices like Safety PLCs.
- Functional Safety: Executing safety functions and achieving safety integrity.
Functional Safety Flow
The functional safety lifecycle includes:
- Hazard analysis: Identifying hazards and defining corresponding safety functions.
- Risk assessment: Assigning Safety Integrity Levels (SIL) based on hazard frequency and severity.
- Safety Function design: Ensuring compliance with IEC 61508 requirements.
- System verification: Testing to confirm the assigned SIL level is achieved (e.g., SFF, PFH).
- Audit: Verifying that all lifecycle steps were conducted using appropriate management techniques.
