If you’ve got lots of proven field history for a product, you should be able to claim that good work and get your product certified for use in functional safety applications. It is certainly still a challenge, but it is easier than certifying a new product. The…
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.

All data breaches expose some type of IT (Information Technology) or OT (Operating Technology) system vulnerability. Cybersecurity professionals then need to evaluate and determine appropriate responses for themselves and their clients. It might be patching software, revising work processes or altering incident response techniques.
A Safety Function is the action of a collection of equipment to implement automatic mitigation of a particular hazard. It is the job of the Safety Instrumented Function (SIF).
Some examples of common Safety Functions:
As the name implies, the purpose of Safe Operating Limits (SOL) is to define the limits beyond which a process will not intentionally be operated and at which troubleshooting ceases, replaced by pre-determined actions to bring the process to a safe state. Pretty important information. I am sure this is…

Cyberattacks have become the new norm for industrial control systems. A recent study found that 54% (more than half) of companies surveyed had experienced a cyber-attack on their Industrial control system within the last two years[1].
The need for well-trained, competent individuals to address cybersecurity for industrial control systems…

Walking into work last week and seeing this article reassured me why I work at exida. Incidents, like this recent one at a pesticide plant in eastern China, are why we push every day to help educate people about the importance of functional safety.

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:
This year, make your New Year’s resolution safety!
Take a moment this year and think about where you currently stand with functional safety. And actually, be honest with yourself. REALLY honest. Do you proof test on time, or does it sometimes get pushed out? Do you pull your devices…
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…
When I went to set my goals for 2019, I set both personal and professional goals. One of my professional goals is to clean off my desk, but another is to get more people to think about functional safety before an accident occurs, instead of when they are normally…
