SCADA systems are generally used to monitor and control equipment in industries such as telecommunications, water and waste control, energy, oil and gas refining, and transportation—mainly systems that are geographically widespread. This course explores the evolution of these systems, the differences in the SCADA types, and how they evolved from monolithic to distributed to networked.

This program will review the typical SCADA hardware components, as well as how different telemetry points are processed and the data flow all the way from the field, through RTU, to front-end processor, to control room. Attendees will discuss how data can be processed for the end user, as well as alarm processing, switching controls, processing logic in database, and putting it into the dynamic graphic user interface for end-to-end control and monitoring.  

SCADA 101 will explore the best data maintenance practices, such as maintaining data standards and templates, creating the point list and checkout lists, performing point-to-point testing, and maintaining the quality assurance systems independent from productions where jobs are run first. It will also go over the uses of dispatch training system for the real-time data and data analysis for performing various actions to the system and how they affect the systems.  

In the end, students will gain a solid understanding of how SCADA systems work, how and why they were developed, how they are structured, its database and data collection techniques, and the uses of the dynamic data by the end user.
