IEC 61508 (ed2.0, 2010.4) • Functional safety of electrical/electronic/programmable electronic safety-related

systems• 적용범위 : E/E/PE 시스템이안전관련기능을수행하는 E/E/PE 시스템, other technology, 외부 Risk 감소설비

Functional Safety in IEC61508• 기능안전(Functional Safety)?

− Safety의한부분으로, EUC 및 EUC Control system의 Safe state를달성하고 유지하여 E/E/PE 시스템의 안전 관련 기능이 정상적으로 수행되는상태

• 안전(Safety)?− 사람의신체에대한물리적인상해나건강에대한해를입히는것뿐만이아니라, 직/간접적인 재산 및 환경적 피해로 인한 허용할 수 없는 위험으로부터자유로운상태

• Risk reduction− Risk analysis를 통해 적합한 기법들을 선정하여 안전 관련 시스템이

Tolerable risk를달성

• Random Hardware Failure :

노화등으로인해랜덤하게발생되는 H/W적인 Failure

방법 : Redundancy, diversity, diagnostics, reliability

• Systematic Failure : 제조프로세스, 운영프로세스, 문서화등주로체계적인부분에서발생 S/W적인Failure

방법 : V-model

• Safety Lifecycle(SLC) : Systematic error를줄이기위한접근모델

• Probabilistic Failure Analysis : SIL 등급을정하기위한정량적(확률적) 분석
