Recorded Webinars: Does Having an Integrated Valve Assembly Actually Create Lower Failure Rates?
When doing FMEDAs and analyzing designs, we theorized a portion of failure rates are because of failures in design themselves. If really good engineering process and procedures are created (and actually used!), a portion of field failures can be eliminated. The same goes for final element assemblies. Perfect integration is not assumed. So if your final elements are integrated, there are failures that will be eliminated! This webinar will look at what we investigate when do an integrated valve assembly assessment and how it directly impacts failure rates.
Blog Entry: Back to Basics 01 - Functional Safety
In the following series of blogs, we'll go back to basics and run down everything you need to know to get started in functional safety. We'll start with some more general terms and descriptions and make our way to more advanced material. 1. Functional Safety Functional safety means the automatic…
Recorded Webinars: IT and OT Cybersecurity, Two Sides of the Same Coin?
Information Technology and Operational Technology are the two groups responsible for managing industrial cybersecurity, but often they work separately with little communication or common understanding of how each groups’ objectives play a role in the overall cybersecurity of the IACS. Developing clear communication and common understanding between IT and OT groups is essential for securing the IACS from the business network to the BPCS and SIS zones.
Co-presented by exida Senior Cybersecurity Engineer Robert Michalsky.

News Item: Upcoming Webinar:IEC 62443 Cybersecurity Certification Explained: Requirements, Process, and Benefit
Event Date: March 14, 2019 The ISA/IEC 62443 standards are an industry-driven set of requirements for automation system cybersecurity best practices. Many automation system manufacturers have successfully achieved ISA/IEC 62443 certification, and others are currently working hard to get there. This is because automation systems have become a hacker target.…
White Paper: A Common Development Process for IEC 61508 and IEC 62443
A good product development process should ensure a good understanding of what is to be developed, how it is to be developed and that it was developed correctly. IEC 61508 and IEC 62443‑4‑1 both have development process requirements. These requirements overlap and separate efforts when assessing compliance to both standards…
Recorded Webinars: Key Time Parameters in Functional Safety
There are several time parameters that are used in functional safety. Some of these parameters seem counterintuitive, e.g. a device with an average failure rate of 100 years but it fails after 10 years. How do these numbers align? Terms like useful life and Mean Time To Failure seem to contradict each other. In SIL verification calculations Mission Time is used, how does this fit in? This webinar will talk about the different time parameters and how they are used in functional safety. It will provide a basic understanding of the time parameters.
Recorded Webinars: Drowning in Alarm Floods? Learn how Automatic Alarm Flood Suppression Can Help
The period after an equipment trip or shutdown is one of the most stressful and challenging times for operators. Part of the challenge stems from alarm floods; when the operator gets more alarms than they can respond to. If unabated, alarm floods can lead to a loss of situation awareness, the missing of alarms, operator error, or an incident. Alarm floods are one of the hardest alarm management issues to solve.
This presentation will discuss how you can eliminate alarm floods by designing and implementing alarm flood suppression logic in the control system. It will cover the best practices for design and implementation from ISA-18.2 / IEC 62682. It will show how to implement alarm flood suppression automatically in a DeltaV system using SILAlarm and pre-defined control modules. It will also show examples of how suppression can be implemented in Siemens PCS 7, Rockwell PlantPAx, and Yokogawa Centum systems.
