The IEC61511 Standard is built around a safety lifecycle (SLC) to provide a consistent approach to risk identification and risk reduction, in accordance with a company’s tolerable risk, following best practices. By following the SLC it provides a means of achieving optimum design that balances risk reduction with performance.
What governs the SLC is Functional Safety Management (FSM), which requires a plan to be in place that defines how functional safety will be managed throughout the entire SLC. FSM requires that there be processes and procedures in place, that are monitored and audited, to facilitate FSM. It also requires a competency plan to be in place to ensure staff are properly trained and regularly assessed. This needs to happen at all levels within the company, with anyone involved in SLC activities and/or tasks.
Managers need to also be competent when it comes to managing SLC tasks and being responsible for personnel who are performing SLC tasks. Understanding the importance of performing preventative maintenance and mechanical integrity to maintain process safety is key; arbitrarily cutting expenditure on maintenance and proof testing could lead to serious incidents. Managers who don’t understand the ramifications and/or can justify why budget cuts were made could end up being held accountable and could be prosecuted. Deniable culpability will not be a defense.
This webinar will highlight the importance of understanding FSM and how FSM can be managed and maintained. Executives, Managers and Supervisors should be aware of this and understand the ramifications.
After a number of cybersecurity attacks on industrial control systems (ICS), most plant owner/operators now consider a cybersecurity attack to be a credible risk. In 2007 the ISA Security Compliance Institute (ISCI) was founded and defined the first cybersecurity certification scheme. Now in 2018, IEC 62443 standards have since been released, new schemes have been defined based on cybersecurity experience and these new standards. The presentation will describe the IEC 62443 Certification Program based on the progression of the IEC62443 standard.
It always amazes me that when teaching our FSE 100 Functional Safety Engineering course, the number of times I find that end users in the class are not really measuring the performance of their SIS. In most cases, they are doing some measurements, but not thoroughly. It was partly for…

Optimal Automation System Product Development -Tools for Functional Safety (IEC 61508) and Cybersecurity (IEC 62443)
This webinar will describe an example product development process for both hardware and software that covers requirements of IEC 61508 for functional safety and IEC 62443 for automation system cybersecurity. Engineering tools have been shown to be effective in reducing man hours and calendar time but perhaps more importantly in reducing design faults resulting in higher design quality. The webinar describes how some of the tools achieve these results. As an example, the FMEDA process for hardware design verification is explained using the FMEDAx tool.
exida was the first Accredited Certification Body for cybersecurity when the ISA Security Compliance Institute (ISCI) released its control system cybersecurity certification scheme many years ago. ISCI has continued to advance moving to the IEC 62443 series of standards. A webinar will be presented by Andre Ristaino, Managing Director, ISA…
Reliability Engineers know that the ultimate source of realistic failure rate data is actual field failure data from a similar environment. There is even strong language in the new IEC 61511 standard requiring field failure based numbers. In this webinar, different methods used to estimate and predict failure rates are explained. A combination method using all data, called the Calibrated FMEDA™, has been developed which not only predicts failure rates based on field failure data but includes proof test coverage as well.
While discussing functional safety certification of an integrated valve assembly with a manufacturer, exida stated that all devices (actuator, pneumatic parts, valve, etc.) must be IEC 61508 certified . The manufacturer said this was no problem, and provided a set of exida and TÜV certificates. Of course, we need good…
Sellersville, PA: The global leader in functional safety, cybersecurity, and alarm management for the process industries, exida, has introduced an extensive CSP (Cybersecurity Practitioner) Program developed by top ICS cybersecurity experts, each with over 30 years of experience. The CSP Program consists of various IEC 62443-based IACS (Industrial Automated Control…
Proof test coverage is an important variable in Safety Instrumented System design that can impact risk reduction by an entire SIL level. This is shown in PFDavg calculations. Most engineers who design and verify safety instrumented functions (SIFs) understand how hard it is to design a manual proof test with high effectiveness (also called high proof test coverage).
This webinar will show that the real objective is to detect failures NOT detected by automatic diagnostics explain proof test coverage, why this is an important safety parameter, and will explain how proof test coverage is calculated, showing several examples of proof test procedures along with the test coverage.
This subject is covered more in depth in exida’s latest publication Final Elements in Safety Instrumented Systems, IEC 61511 Compliant Systems and IEC 61508 Compliant Products.
Though this is largely true, I want to discourage people from completely ignoring the good things that IEC 61508 does for the end user. IEC 61511 is the process industry functional safety standard derived from IEC 61508. In the very first section of IEC 61511 (“Scope”), the standard describes exactly…

Splint is offering to present a “special reward” to the “first person to produce a real program that produces no errors with strict checking.” Here’s a summary of a recent real-world automotive project attempting this. TL;DR: We were not successful, but we learned a few things about MISRA compliance. Feel…
