What component would you use to monitor the real-time data in a SCADA system?

In a SCADA (Supervisory Control and Data Acquisition) system, the Human-Machine Interface (HMI) is the component used to monitor real-time data. The HMI serves as the graphical user interface that allows operators to visualize and interact with the processes being monitored and controlled within the system.

The HMI displays real-time information such as system status, alarms, and trends which helps operators to make informed decisions. It often includes visual representations like graphs, charts, and maps that can showcase data in an easily digestible format. This enables quick assessment of the system’s operational status and facilitates timely responses to emerging issues.

While other components like the Master Station, Remote Terminal Unit (RTU), and communications modules also play vital roles within a SCADA system, the HMI is specifically designed to provide an interactive platform for monitoring and managing the real-time data effectively. The HMI's functionality is crucial for ensuring that operators have the necessary information at their fingertips to maintain system efficiency and safety.
