Blog Entry: Delivering Situation Awareness During an Alarm Flood: Throw Your Operators a Lifeline
Alarm floods are periods of alarm activity during which the alarm rate is greater than the operator can effectively manage (e.g., when the operator receives ≥10 alarms in 10 minutes). During a flood situation awareness is compromised and alarms are likely to be missed. In the eleven minutes prior to…
Recorded Webinars: Efficiently Configure your Safety PLC Application Program
exida’s exSILentia® SILver™ module is the gold standard for SIL verification in the industry. For almost 20 years it has allowed users to design their safety instrumented systems by defining architecture, voting, and equipment selection and ensuring the safety integrity of each instrumented function. The conceptual design as documented in SILver™ in combination with the Safety Requirements Specification (SRS) specifies the requirements for the application program of a SIF/SIS’s a logic solver. Converting these requirements can be time consuming and can be prone to errors due to misinterpretation of the requirements.
Using the exSILentia® SIS Logic module, the application program can be automatically generated with the click of a button. Apart from time savings due to automatic conversion, an additional benefit is the ability to start the logic creation process later in the project schedule avoiding costly redesign activities. This webinar will review the possibilities of automatic application program creation and demonstrate the SIS Logic module as well.
Blog Entry: The Site Safety Challenge – Do You Follow Good Site Practices?
The question of whether companies follow good site safety practices is an interesting one. Firstly, what do we mean by good site safety practices? I think most companies believe they follow good site safety practices but do they really? Are they really measuring and tracking this? The basis of having…

Blog Entry: Back to Basics 17 - PFH (Probability of dangerous Failure per Hour)
PFH (Probability of dangerous Failure per Hour) is the probability that a system will fail dangerously, and not be able to perform its safety function when required. PFH can be determined as a probability or maximum probability over a time period of an hour. IEC 61508 and IEC 61511 use…
Recorded Webinars: Choosing the Best Functional Safety and Cybersecurity Certification Path
With the rapid growth of IEC 61508 Safety Integrity Level (SIL) Certification and now IEC 62443 Cybersecurity Certification, many companies are trying to catch up and understand what is involved. Manufacturers, System Integrators, and End Users have MANY different options when obtaining certification. Certification with exida is now molded around the company and NOT around the certifying body. How much time will it take? How much will it cost? How many man hours will be consumed to achieve certification? What are the benefits? These are now ALL questions our potential customers have the ability to choose!

Recorded Webinars: Back To Basics – Systematic Capability, Architectural Constraints and PFD? Oh my!
Once again, we’ll go back to basics and run down everything you need to know to get started in functional safety. This webinar will focus on Systematic Capability, Architectural Constraints and the Probability of Failure on Demand (PFD).
We will look at:
- Systematic Capability: What it is, how a products gets it and where you can find it
- Architectural Constraints: How it is defined, what it actually means and the different “Routes” approach
- PFD: What it is, the equation and its variables
Along with how each play an important role in SIF design and safety.
Blog Entry: Guest Blog: Thar’s Gold in Them Thar Failure Data
Failure data collection can seem tedious, time consuming and expensive. Just figuring out what data to collect can be challenging. Failure data analysis can be overwhelming with a sense of “I don’t even know where to begin.” So it is not surprising that these useful, vital activities are often neglected…
