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.
Blog Entry: exida Failure Rates are Higher Than TÜV Italia. Who Is Right?
An owner-operator engineer compared the failure rates for two similar products from an exida certificate with those from a TÜV Italia certificate. exida numbers were an order of magnitude higher. Who is right? There are some relevant fundamental facts in the field of Reliability Engineering: Failure rate prediction methods depend…

Recorded Webinars: Integration Cybersecurity: Understanding and Applying IEC 62443-2-4
IEC 62443-2-4 documents “a comprehensive set of requirements for security capabilities for IACS service providers.” These requirements can be applied to integration or maintenance service providers and documents a framework for negotiations between asset owners and IACS service providers for cybersecurity requirements. This webinar will cover the structure and key concepts from the standard, as well as introduce the process of IEC 62443-2-4 certification, and the benefits that certification can provide to integration and maintenance service providers.

News Item: New White Paper: Considering Multiple Initiating Events in a LOPA
Layer of Protection Analysis (LOPA) is a risk reduction evaluation methodology well suited to consider hazard scenarios with multiple initiating events. The presence of multiple initiators increases the likelihood that a hazard scenario could occur placing additional demands on the Independent Protection Layers (IPLs) that prevent and mitigate the hazard.…

Blog Entry: What can OT learn from IT data breaches?
Does your organization even have a CISO position? Cybersecurity continues to be an overlooked aspect in organizations—including those owning ICS (Industrial Control System) production facilities. Anyone following the news has most assuredly heard of the plethora of massive data breaches that organizations have endured over the last few years, and…
Recorded Webinars: Back to Basics: All About Failure Rates
We will head back to the basics and break down everything there is to know about failure rates. We will learn:
- What a failure rate is
- How the standards define them
- Their unit of measurement
- Types of failure rates and failure modes
- Where do you get failure rates from
- How did a failure rate for a product get determined
- How you know if the failure rate is appropriate for your application
- What to do if it’s not
And of course, take time at the end to answer any question you may have about failure rates!
