Recorded Webinars: What Does “… failures which are the responsibility of the manufacturer were examined” Mean ?
What does “… failures which are the responsibility of the manufacturer were examined” mean with failure rate data?
There are a few assumptions that make a large difference in failure rate data. One of these is the definition of a “failure.” On any valid certificate, information is given to help the user understand the data. It is critically important to anyone using the data for SIL verification. This webinar shows examples of failure rate data provided by certification bodies and explains qualifying statements provided on the certificates.
Blog Entry: Are Your Control Systems Really Protected?
I don’t know whether you’ve noticed recently, but the number of cybersecurity alerts issued by CISA (Cybersecurity and Infrastructure Security Agency) seems to be increasing at an alarming rate. The latest alert I’ve seen now relates to GPS tracking systems for children. A device which is supposed to keep your…

Blog Entry: Back to Basics 14 - Systematic Capability
Systematic Capability is achieved when the equipment used to implement any safety function achieves two goals: the design process has used procedures intended to prevent systematic design errors (fault avoidance) and the design has systematic design control mechanisms such as a diagnostic for incorrect software execution (fault control). The rigor…
Recorded Webinars: Why People Dangerously Ignore Motor Controllers in a SIF
In the process industry, Motor controllers are often used in safety instrumented functions to de-energize pumps, fans, and rotating equipment. These devices are often ignored in SIF design verification because IEC 61508 certified devices are hard to find and failure rate data is often not available. This webinar explains how to fill that void by informing where to get failure rate data for these important devices and gives examples of using both a certified device with actual FMEDA data and generic failure data.
Blog Entry: Let’s Talk About Configuration Management and ISO 26262
Most software developers are familiar with the need for and benefits of change control. Usually change control means one thing to a software developer and that is 'commits' to a source code revision control system. Not only do small and regular commits provide significant advantages to large teams of developers…

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.
