What is SCADA?
SCADA (Supervisory Control and Data Acquisition) is a system of software and hardware elements that allows industrial organizations to control processes locally or at remote locations, monitor, gather, and process real-time data, directly interact with devices such as sensors, valves, pumps, motors, and record events into a log file.
Key Components
- Human-Machine Interface (HMI): The user interface that presents data to a human operator.
- Supervisory System: Centralized software for data collection and control.
- Remote Terminal Units (RTUs): Field devices that connect to sensors and actuators.
- Programmable Logic Controllers (PLCs): Industrial computers that control processes.
- Communication Infrastructure: Networks that connect the SCADA components.
SCADA Development Process
- Needs Assessment: Define system requirements, process goals, and integration needs.
- System Design: Architect the SCADA network, select hardware/software, and design HMIs.
- Programming & Configuration: Develop PLC/RTU logic, configure communication protocols, and build HMI screens.
- Integration: Connect SCADA to existing systems (e.g., HVAC, manufacturing lines, utilities).
- Testing: Simulate operations, verify data accuracy, and ensure system reliability.
- Deployment: Install hardware, deploy software, and commission the system.
- Training & Support: Train operators and provide ongoing technical support.
