Yokogawa Technical Report

Improved plant operation efficiency and reduced maintenance costs based on appropriate predictive maintenance are the common objectives that need to be achieved in every manufacturing domain. Exaquantum is positioned above the Process Control System (PCS) layer and gathers and stores huge volumes of process and laboratory data over long terms.


ARC believes that by implementing procedural automation, many process plants can minimize variability to help ensure smooth, efficient, and safe state transitions.


Modern historians do much more than just store process data. They also provide analysis, reports, and valuable operational and business information.
