What is functional safety for AI?
Functional safety for AI is making sure that AI systems work reliably and predictably, even when there are problems, in industrial settings. This idea is very important in instrumentation and control systems when AI is used for safety-related tasks including monitoring, diagnostics, and making decisions on its own.
Standards like IEC 61508 and IEC 61511 manage traditional functional safety, which aims to stop dangerous failures in systems like pressure transmitters, control valves, and distributed control systems (DCS). When AI is added to these systems for predictive maintenance, anomaly detection, or adaptive control, it must be thoroughly tested to make sure it doesn’t lower safety integrity levels (SIL).
AI algorithms, particularly those utilizing machine learning, present distinct obstacles. Their behavior can change over time, which makes it harder to be sure that their replies will always be the same. So, for AI to be functionally safe, it needs to be able to explain itself, be traceable, and be tested thoroughly in a variety of situations. It also needs protections to stop harmful activities that could happen because of wrong predictions or bad data inputs.
This means that AI-enhanced devices used in industry must be able to fail safely, keep control when things are uncertain, and follow cybersecurity rules like IEC 62443. A smart pressure transmitter that uses AI to compensate for drift, for instance, must not turn off important warnings or ignore safety logic in a safety instrumented system (SIS).
In the end, functional safety for AI means that smart technologies make operations more efficient without adding new hazards. This keeps industrial processes safe and protects people, property, and the environment.
