HMI (Human-Machine Interface) and SCADA (Supervisory Control and Data Acquisition) are critical components in industrial automation and control systems. They are used to monitor, control, and manage industrial processes and equipment.
Key Features:
- Data Acquisition:
- Collects real-time data from sensors and devices.
- Uses Remote Terminal Units (RTUs) and Programmable Logic Controllers (PLCs).
- Data Communication:
- Transmits data between field devices and the central control system.
- Common protocols: Modbus, OPC, MQTT.
- Centralized Monitoring:
- Displays system-wide data on screens at a control center.
- Example: Monitoring an entire power grid from one location.
- Control Capability:
- Allows remote control of processes like opening/closing valves or adjusting setpoints.
- Historical Data Logging:
- Stores data for analysis, reporting, and optimization.
Applications:
- Power distribution systems
- Oil and gas pipelines
- Water and wastewater management
- Transportation systems …….etc
