Probabilistic Safety Management of Control Logics According to IEC 61508 (PSAM-0259)


This paper presents a fault-tolerant control logic design framework using a safety performance index. Using the presented framework, we can design a control logic achieving necessary risk reduction according to the international safety standard, IEC 61508. It is probabilistic safety management of control logics according to IEC 61508. It clarifies that safety is one of most important performances in control logic design.
