Blog Entry: Do You Really Know What You Know (When it Comes to Functional Safety)?
You don’t’ really know what you know until you have to explain it (or teach it) to someone else. When I’m asked about some of the technical aspects of functional safety, I have to stop and ask myself “What Do I Know About This?” I’m not the kind of guy…
Recorded Webinars: Getting Failure Rate Data for Motor Controllers
Most final element device like values, actuators and relays are readily available with IEC 61508 certification and model specific failure rates. However it seems as if motor controllers got left out. Motor controllers are an important part of many safety instrumented functions (SIF). Like all electronic devices, dangerous failures can occur. Therefore it is important to be able to get failure rate data for these motor controllers. This webinar shows the recent motor controller update to the exida failure rate database used in the exSILentia software and how that data can impact the risk reduction capabilities of a SIF

Recorded Webinars: How Final Element Proof Test Can Affect Your Safety Instrumented Function (SIF)
Last week exida was at the ISA Energy and Water Automation Conference and presented on Proof testing your SIF. This webinar will recap the information we shared.
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.

Blog Entry: Building Cybersecurity into Software Applications
An April 2019 report from the Institute of Critical Infrastructure Technology (ICIT) makes the point that even though software ‘runs the world’, software security is an afterthought across virtually all industries. The report states that this lack of software security is actually a National Threat given that this approach leads…

Recorded Webinars: How exida is Changing the Functional Safety and IACS Cybersecurity Industry
In 20 short years exida was formed and became the #1 certifying body in the world. With exida’s growth continuing, and achieving another company growth record in 2018, people are asking: Who is exida? How and why did exida form? What makes exida different? Why are companies changing from other certifying bodies?
This webinar will share with you some of our personal stories on how we formed, the exida failure rate database, why exida publishes a plethora of reference material, and more.
Recorded Webinars: Process Safety: Why it’s important to consider more than one lifecycle
When it comes to process safety, most companies will focus on the functional safety lifecycle and compliance with IEC61511. However, with the advent of the industrial internet of things (IIOT) and the growing use of wireless technologies, it is becoming more important to consider cybersecurity and the consequences of control and safety systems being compromised due to a cyber-related incident. Similarly, if there is no defined alarm philosophy and rationalization of alarms, operators can miss vital alarms and lose valuable time in being able to respond to an incident due to the volume of alarms being generated. Accidents, such as the Buncefield and Texas City explosions, highlighted the problem with operators being confused by too many alarms.
Since the standards for functional safety (IEC61511), alarm management (IEC62682) and cybersecurity (IEC62443) all follow a similar 3 phase lifecycle, it makes sense to consider all 3 together, when it comes to process safety. As such an integrated lifecycle approach will help in reducing overall operational costs via increased efficiencies.
This webinar explores the overlap between the lifecycles and how synergistic benefits can be gained by considering all 3 together.

Blog Entry: When is an Alarm not an Alarm?
The ISA-18.2 and IEC 62682 standards define an alarm as an “audible and/or visible means of indicating to the operator an equipment malfunction, process deviation, or abnormal condition requiring a timely response”. One of the reasons why alarm systems are out of control (alarm overload, nuisance alarms) is because the…
