A practical operating-event journey

This walkthrough uses an illustrative 500-alarm scenario to explain how the modules work together. The existing OSM-18 executable synthetic reference contains a smaller compressor-trip alarm cascade and demonstrates State, Situation, workflow and recovery logic; a 500-alarm benchmark has not been established.

OSM analyzes evidence and publishes context. The DCS remains responsible for alarms and control. Customer-defined workflows, existing-interface integrations, Buddy experiences, Memory Lanes governance and site engineering acceptance depend on approved implementation. SOP, BPCS and SIS changes require authorized human review and established management of change.

OPX AI applies ISA-18.2-informed alarm engineering and relevant functional-safety engineering practices; this is not a claim of certification or site compliance.
