SIS-TECH

Correctly identifying the instrumented protective systems (IPS) needed for a facility is an indispensable step in executing functional safety. However, instrumented systems must also be carefully specified and designed to succeed in achieving the safety performance assumed in H&RA studies.

In the sixth episode of the “Safe Automation in the Process Industry” webinar series, we:

• Summarize the content of a high-quality specification for both LI-PL and SIS,      
• Review additional design constraints that apply to SIS, and
• Discuss designing the LI-PL and SIS to make them more operable, maintainable, and easier to include in monitoring programs.
