Recorded Webinars: Tools for Functional Safety (IEC 61508) and Cybersecurity (IEC 62443)
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.
News Item: Upcoming Webinar on IEC 62443 Conformance Certification
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…
Recorded Webinars: Realistic Failure Rate Data – the Calibrated FMEDA™
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.
Blog Entry: Does Everyone Really Ignore Failure Rates?
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…
News Item: exida Introduces IEC 62443 Cybersecurity Certificate Program
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…
Recorded Webinars: Final Element Proof Tests
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.
Blog Entry: Fake Fact: IEC 61508 Does Not Affect Me As an End User
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…

Blog Entry: Which FSAs Do I Have to Perform?
The new release of IEC61511:2016 has caused some confusion when it comes to the Functional Safety Assessments (FSAs). Which ones are mandatory? The confusion comes from the wording in the standard and the clarifications in the notes. The relevant clause in the standard 5.2.6.1.4 states: A FSA team shall review…
