A plant historian turns raw control signals into usable history. It continuously gathers values and events from PLCs, RTUs, DCS/SCADA, and smart instruments, then stores them with precise timestamps. Teams use the historian for trends, dashboards, KPIs, root-cause investigations, regulatory reports, and data sharing with enterprise analytics—without touching the live control system.
Tip: The interactive version includes progress tracking, decks, and premium deep dives.
