SCADA (Supervisory Control and Data Acquisition) systems are centralized platforms that monitor and control industrial processes, using hardware (PLCs, RTUs, sensors) and software (HMIs) to collect real-time data, provide visualization, enable remote control, manage alarms, and log history for improved efficiency, quicker decision-making, and predictive maintenance in sectors like energy, water, manufacturing, and transportation. Data acquisition solutions integrate with SCADA by collecting raw data from field devices (machinery, sensors) and transmitting it to the supervisory system for processing and action. 

Key Components & Functions:

• Data Acquisition (DAQ): The process of collecting real-time data from physical sensors and equipment using devices like PLCs (Programmable Logic Controllers) and RTUs (Remote Terminal Units).
• Supervisory Control: Operators use Human-Machine Interfaces (HMIs) to view data, send commands, and manage processes remotely or locally.
• Real-time Monitoring: Continuous tracking of operational status, variables, and alarms.
• Remote Control: Ability to adjust equipment (motors, pumps) from a central location.
• Alarm Management: Configurable alerts for critical events, enhancing safety and preventing downtime.
• Data Logging & History: Recording trends and events for historical analysis, reporting, and predictive maintenance.
• Communication Protocols: Utilizes standards like Modbus, OPC, Profibus, and Ethernet/IP for device communication.
