SIS mode (optional)

Safety instrumented systems

For zones containing a Safety Instrumented System, this mode combines conventional LOPA with cybersecurity through Cyber-LOPA. It works on a copy of the LOPA study and assumes that some barriers are compromised by an attack to determine whether the protection level still holds.

What you will do

1. Enable the 'SIS Analysis' profile for the relevant zone.
2. Import or reference the original LOPA scenario from the Industrial Risks module.
3. Review the Cyber-LOPA. It never changes the source LOPA study and works on a dedicated copy.
