3 OVERVIEW OF IEC 61508 3.1 Origins of IEC 61508 By the 1980s, software had become the first choice of most design-ers of control systems. Its apparent speed of production, the cheap-ness of its reproduction, and the ease with which it facilitates the intro-duction of new facilities, made it more attractive than purely hard-ware solutions.

Missing page numbers correspond to the French- IEC 61508 does not cover safety issues like electric shock, hazardous falls, long-term exposure to a toxic substance, etc.; these issues are covered by other standards. IEC 61508 also does not cover low safety E/E/PE systems where a single E/E/PE system is capable of providing the Understanding Safety Integrity Level IEC 61511. Assignment of SIL is an exercise in risk analysis where the risk associated with a specific hazard, that is intended to be protected against by a SIF, is calculated without the beneficial risk reduction effect of the SIF. That unmitigated risk is then compared against a tolerable risk target.

IEC 61508 is an international functional safety standard and it provides a framework for safety lifecycle activities. Titled “Functional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems (E/E/PE, or E/E/PES)”, 61508 is the umbrella functional safety standard — and the source for industry-specific standards.

For applications requiring IEC 61508 certifications, a pre-certified IEC 61508 SIL 3 RTOS kernel is available. IEC 61508 is an international standard for the functional safety of electrical/electronic, programmable electronic systems (PES) and is well established in the industrial process control and automation industry.

Mitsubishi Electric Corporation announced today that it will launch its newest MELSEC iQ-R Series general-purpose programmable controller, the IEC 61508 SIL 2-compliant redundant programmable controller paired with a redundant-function SIL2 CPU set for … Because IEC 61508 serves as the meta-standard for a range of industries and published standards, the Platform for Industrial Safety is directly applicable to railway (CENELEC EN 50128), medical (IEC 60601), nuclear (IEC 61513), process control (IEC 61511), and automotive (ISO 26262).

What is a safety PLC? Let’s try to explain it in a simple way for non-experts. The fundamental difference with a general purpose PLC is summed up in one word «Diagnosis».In addition, there are differences in terms of internal architecture, software and firmware, and certification for applications where compliance with a certain SIL level is required. Safety Trip Alarm SIL2- and SIL3-Certified to IEC 61508.

Lo IEC 61508 è uno standard internazionale che disciplina l'intero ciclo di vita dei prodotti e dei sistemi elettrici, elettronici o elettronici programmabili (E/E/PE) relativi alla sicurezza, inclusi la loro applicazione, progettazione, utilizzo e manutenzione. È sviluppato dalla Commissione elettrotecnica internazionale (IEC) e ha come titolo Sicurezza funzionale dei sistemi elettrici IEC 61508-6 has been prepared by subcommittee 65A: System aspects, of IEC technical committee 65: Industrial-process measurement and control. The text of this standard is based on the following documents: However, IEC 61508 allows more flexibility for their Hazard and Risk Analysis in which various techniques can be used to evaluate hazards, including techniques common in the ISO 12100 standard. Additionally, IEC 61508 calls their stringency levels Safety Integrity Level (SIL); whereas, ISO 26262 uses Automotive Safety Integrity Levels (ASIL).
