Faults detection and alarms display is the main part of Downtime Reduction School training. This is crush course and a main part of the Downtime Reduction Methodology. From the image above you can a control system room with HMI and SCADA screens. The top screen displays a process, all components and devices, as well as their states. An actual graphic style and color are taken from DCS — Distributed Control System. Students will learn how to properly display different element of the process and instrumentation screen.
