If you are unable to attend at the scheduled date and time, we make recordings available to all registrants for three business days after the event

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. 

Our instructor, a Principal Database Specialist with Xcel Energy, will guide attendees through an intensive review of:

  • Typical SCADA hardware components
  • How different telemetry points are processed
  • Data flow from the field, through RTU, to front-end processor, to control room
  • How data can be processed for the end user
  • Alarm processing
  • Switching controls
  • Processing logic in database, and putting it into the dynamic graphic user interface for end-to-end control and monitoring
  • Best practices in data maintenance
  • The uses of dispatch training system for real-time data analysis

Attendees will leave with 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.
