![]() ![]() SCADA HMI collect and process real-time data from power devices, display it through one or more HMI devices, and provide real-time alarms and notifications of operating conditions. SCADA HMI also supports system testing and is responsible for monitoring building power metrics and displaying them to users. In addition, SCADA HMI maintain logs that enable users to view events and alarms as they occurred. They also monitor the control system and power switching equipment, and alert users when problems are detected in Programmable Logic Controllers (PLCs), circuit breakers, protective relays, generators, and other devices. They enable the adjustment of priorities, time delays, operating modes, test features, and more. SCADA HMIs process user inputs to set operating parameters in electronically controlled equipment. ![]() ![]() Today, SCADA HMI functionality enables advanced graphical display and interaction for monitoring equipment and systems in many industries and applications. Over time, the information managed by SCADA systems increased in scope and complexity, resulting in the increasing integration of HMI and SCADA technologies. Historically, SCADA systems have enabled the monitoring and control of electrical systems through discrete communication channels. This article describes SCADA HMI generally and summarizes how it is often used in backup power systems, including applications served by ASCO Power Technologies equipment. Supervisory Control and Data Acquisition (SCADA) Human Machine Interface (HMI) systems are used in monitoring equipment across many industries and applications, including emergency power. ![]()
