What is a Safety Instrumented Function?

What is a Safety Instrumented Function? One of the most fundamental questions related to Functional Safety and Safety Instrumented Systems is this-what is a safety instrumented function? Once you understand what a Safety Instrumented Function (SIF) means, you will immediately grasp the connection between safety instrumented functions and a Safety Instrumented System (SIS). But more on that later. Any plant or piece of equipment that has the potential to cause harm or damage to itself, the environment or to people needs protective functions. For example your car brake is a protective function. It helps stop the car almost immediately, when for example you spot a pedestrian on the road in front of your car when you are driving it.

Cyber security – Oil and Gas industries

This paper  related to cyber security oil and gas industries, is available as a part of the Abhisam Industrial Cybersecurity report, which can be downloaded now. Author: H Sreedhar. Recent History of Automation in Oil & Gas   The Oil and Gas industry (O & G for short) has been a pioneer in embracing digital technology. It was one of the first industrial sectors to transition to Distributed Control Systems(DCS), from analog electronic control equipment and pneumatic instruments. This transition started in a big way, about 35 years ago, when DCS were a “hi-tech” thing.   O & G is still a tech pioneer, in the era of Industry 4.0 and the Industrial IoT. It quickly embraced concepts like the Digital Oilfield. However, this has led to newer problems related to security. The development of digital control systems and the networking, particularly with the internet, has led to increased risk …
