Recorded Webinars: Designing a Useful and Effective Proof Test
Proof testing is an important part of the management of safety instrumented functions. As an activity required by the functional safety standards, more and more end users are implementing proof tests, but there is often confusion on what should be included in the test and what coverage should be claimed. This webinar will look at techniques to determine what functionality to test as well as coverage. The webinar will also map failure modes from components, to devices, and to elements to illustrate how accurate proof test coverage values can be determined.

Blog Entry: Getting Realistic Failure Rate Data - Part 3
Over the course of several blogs , I will talk about getting realistic failure rate data, where this failure data comes from, and how different methods of failure data analysis compare. I think if you understand this, you will begin to get a very good feel of what it takes…
Blog Entry: The Evolution of Coding Standards
Sometimes it seems that things change slowly in the world of functional safety. If you look at many of the technical references in IEC 61508 you will find that most come from the 1980s and 1990s. There is even one reference that dates back to 1950! With the rate technology…
Recorded Webinars: Master the Destiny of Your Alarm System with a Master Alarm Database
The adoption of standards on alarm management (ISA-18.2 and IEC 62682) have introduced a new term into the lexicon of automation professionals - the “master alarm database,” which is defined as the “authorized list of rationalized alarms and associated attributes.” In this webinar we will talk about what a master alarm database (MADB) is, how one is created, what information it should/could contain, how it can be used to create alarm response procedures, and how it can be integrated into a management of change process. We will also look at how it can be used to document the results of alarm rationalization (e.g., alarm priority, classification, limit, cause, consequence, and corrective action) and other useful design data (e.g., safe operating limits, associated interlocks, maximum design temperatures/pressures). Additionally the webinar will examine how the MADB can be used as the source for updating the control system with the optimized alarm settings resulting from rationalization.

Blog Entry: Close Enough? Not so Much
Performing a SIL Verification calculation on preliminary design information can be a very useful tool to dial in the Safety Instrumented Function (SIF), Safety Requirements Specification (SRS) content , and define critical elements for the field component purchase specifications. Conceptual verification is typically performed quickly with general design information. The…

Recorded Webinars: Why Become a CACE or CACS?
The Certified Automation Cybersecurity Expert (CACE) and Certified Automation Cybersecurity Specialist (CACS) specialties were developed in response to the growing demand to secure industrial automation control systems (IACS) and SCADA systems by providing a means for people to develop and demonstrate competence in understanding and applying security standards and best practices.
This webinar will share why this program was developed and how it will benefit you.
Blog Entry: LOPAx™: This is Awesome!
You will probably not hear me sing the LEGO® Movie’s “Everything is Awesome” song, I’ll keep that private (and you should be thankful to me for that). However as we just released the LOPAx™ module of the new exSILentia® v4 platform, I have come to the conclusion that what we…
Recorded Webinars: Layer of Protection Analysis with LOPAx™
There is no doubt that Layer of Protection Analysis (LOPA) has been widely accepted as the method to use for detailed accident likelihood evaluations. exida has released a new tool, LOPAx™, that allows advanced likelihood evaluations. More importantly the tool is tightly integrated with the exida Process Hazard Analysis (PHAx™) tool. Both PHAx and LOPAx are modules within the exSILentia® safety lifecycle software. The integration of safety lifecycle phases is the key to consistency and efficiency. This webinar will discuss the principles of LOPA and show a live demo of the exida LOPAx software and its integration with the PHAx software.

White Paper: Comparing Certification under IEC 61508 1st Edition and 2nd Edition
An updated version of IEC 61508, Functional Safety of Electrical/Electronic and Programmable Electronic Systems was issued in September 2010. This Second Edition is generally thought to clarify common interpretations of the first edition [N2] and add some refinements that had accumulated in the ten years since the first edition. The…
Recorded Webinars: exida Functional Safety Practitioner (FSP) Certificate Program
This webinar will introduce and discuss the exida Functional Safety Practitioner (FSP) program. This is a certificate program that addresses a growing need to provide confirmation that an attendee showed competency by retaining the knowledge presented in a training course. The FSP program will also provide an analysis of where the candidate’s strengths and weaknesses lie. This program will also help a participant judge their competency level if interested in obtaining a certification like the CFSE or CFSP.
