Safety Instrumented Systems: Bridge the Gap

(Article)

A safety requirements specification often contains assumptions and gaps that can complicate development of a safety instrumented system. It’s important to assess how strong the bridge is for transposing detailed requirements into functional design.

Consider the Impact of Industry 4.0 on Safety Instrumented Systems

(Article)

As “Industry 4.0” gains ground among processors, the greater communication among devices embodied by the concept raises cyber-security challenges for plants’ safety instrumented systems (SISs). Here’s a high-spotting of some important issues.

Proof Test Prudently

(Article)

A safety instrumented system usually includes a variety of low-demand safety instrumented functions (SIFs). Because these SIFs remain dormant for long periods, proof testing is an effective tool to detect and repair failures.
