IEC 61508 (Functional safety of electrical/electronic/programmable electronic safety-related systems) is an international, industry-independent functional safety standard. The seven-part standard spans IEC 61508-1 to IEC 61508-7. IEC 61508-3 is concerned with software development, verification, and validation. IEC 61508-3 highly recommends certified tools and translators for safety integrity levels (SILs) SIL 2 and higher; clause 7.4.4 provides requirements for support tools.

EN 50657: 2017 (Railways Applications - Rolling stock applications - Software on Board Rolling Stock) is a European standard that specifies requirements on development, deployment and maintenance of software intended for railway rolling stock applications. The requirements for software tools are derived from the requirements on software tools according to IEC 61508-3.
One of the most important standards, IEC 61508, is a general "umbrella" standard regulating the Functional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems. codebeamer supports compliance with a variety of safety standards including IEC 61508.
Compliance with standards such as IEC 61508 could give your company access to new markets, and helps build trust towards both your processes and end products, thus building your company's image. Therefore, achieving compliance gives you a competitive advantage, and finding the most (cost-)efficient way to conform with the rules and requirements of IEC 61508 yields immense business value.
IEC 61508 consists of 7 sections detailing the requirements, guidelines and examples of the standard to help its users achieve compliance. It covers basics such as definitions and a glossary (abbreviations), examples and methods that help determine Safety Integrity Levels (SILs), general requirements, guidelines on applying IEC 61508, and requirements of safety-related systems as well as software requirements.
As a complete, integrated end-to-end ALM solution, codebeamer covers all phases of the product development process.

Another key difference is in the risk analysis. ISO 26262 uses a very specific Hazard Analysis and Risk Assessment (HARA) that is built into the standard. 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.
IEC 61508 is an international standard published by the International Electrotechnical Commission consisting of methods on how to apply, design, deploy and maintain automatic protection systems called safety-related systems. It is titled Functional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems (E/E/PE, or E/E/PES).
Before the launch of ISO 26262, the development of software for safety related automotive systems was predominantly covered by the Motor Industry Software Reliability Association (MISRA) guidelines.[3] The MISRA project was conceived to develop guidelines for the creation of embedded software in road vehicle electronic systems.[3] A set of guidelines for the development of vehicle based software was published in November 1994.[4] This document provided the first automotive industry interpretation of the principles of the, then emerging, IEC 61508 standard.[3]
Since when has Pepperl+Fuchs engaged in the field of functional safety? Werner Bansemir: As one of the longest-standing automation companies, Pepperl+Fuchs has been involved in the field of functional safety for a long time now. Since the seventies actually. For us in-house, the initial spark came from a customer request regarding safely shutting down the main fuel supply of combustion plants. The result was the development of the first safety switch amplifier in 1973. The dynamic transmission principle of the switching signal of that era's switch amplifiers still forms the technical basis for safety devices for SIL 3 applications. Stefanie Arnold: A short time later, this was followed by the development of the first proximity sensor for safety applications. These sensors were a further development of standard sensors, which were now able to detect a fault via two additional transistors. The additional components in the sensor were required so that the sensor could still emit a safe signal state any time a fault occurred, i.e., to implement the fail-safe principle. During this development phase, a globally relevant safety framework such as 61508 was still a long way off: At the time, the DIN 4788 standard for gas burners and VDE 0116 standard for the electrical equipment of combustion plants were used as reference.
The INTEGRITY real-time operating system (RTOS) provides the foundation for the Platform. 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.
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).
The MULTI toolchain has been certified to meet the highest levels of tool qualification specified in the IEC 61508:2010 (Industrial), EN 50128:2011 (Railway) and ISO 26262:2011 (Automotive) functional safety standards. MULTI is the only commercially available toolchain certified to satisfy both SIL 4 (Safety Integrity Level) and ASIL D (Automotive Safety Integrity Level) tool qualification requirements.
