HMI (Human–Machine Interface) and SCADA (Supervisory Control and Data Acquisition) are two key technologies used in industrial automation and process control.
HMI (Human–Machine Interface):
An HMI is a graphical interface that allows human operators to interact with machines, systems, or processes. It displays real-time data (like temperature, pressure, or motor speed) and lets users monitor and control equipment through touchscreens, buttons, or keyboards.
Example: Mitsubishi GOT1000 or Siemens TP series panels.
SCADA (Supervisory Control and Data Acquisition):
SCADA is a larger control system that collects, monitors, and analyzes data from multiple remote locations. It supervises entire plants or distributed networks (e.g., power grids, water systems) using sensors, PLCs, and HMIs.
