In the previous blog, it is discussed that how IEC 62443 can help an asset owner. In this blog, let us have a look at how IEC 62443 is useful for IACS service providers. IEC 62443-2-4 and/or IEC 62443-3-3 will apply to you if you are a system service provider who provides system integration service […]
When I was a kid, I liked watching the Jetsons. I felt certain that by the year 2000 we’d all be enjoying those flying saucers and futuristic homes. Imagine my disappointment that in 2018 we still drive on 4 wheels… and my home cannot elevate itself above bad weather… and I still don’t have a […]
[:en][vc_row][vc_column][vc_column_text]In this blog series, I will cover the emerging trends in the valve assembly market, how these trends relate to the IEC 61511 requirements, and what’s in a final element. When you look at the different devices that go into some of these safety systems, the final element becomes quite complex. I will also cover […]
[:en][vc_row][vc_column][vc_column_text]Ehh… If your safety action is stopping flow/closing a valve, how are you going to accomplish this if you consider that the remote actuated valve is not part of your SIF ? So, what is this myth based on? The title of IEC 61508 reads “Functional safety of electrical/electronic/programmable electronic safety-related systems”. The argument typically made […]
[:en][vc_row][vc_column][vc_column_text]Estimating time and cost for a project, or even part of a project, can be tricky. Breaking down the tasks into subparts must be done or you don’t stand a chance. Given enough time, you can develop an accurate estimate and put a good plan in place. But sometimes you can’t flush out all the […]
[:en][vc_row][vc_column][vc_column_text]Both IEC 61508 and ISO 26262 highly recommend a modular approach to software development. One question that comes up regularly asks if there are quantitative targets for determining whether sufficient progress has been achieved by software engineers. IEC 61508-3 Table B.9 Modular approach ISO 26262-6 Table 1 Topics to be covered by modelling and coding […]
