SCADA system (definition)

SCADA system (Supervisory Control and Data Acquisition) is a comprehensive software and hardware designed to control and monitor various processes and systems in real time. It integrates various components such as sensors, controllers, communication networks and user interfaces to provide operators and engineers with complete control and the ability to remotely manage distributed production and infrastructure systems.

Main components of the SCADA system:

1. Communication channels — means of data transmission, including wired and wireless networks, for communication between various devices and the central control system.
2. Controllers — devices that perform the functions of collecting data from sensors and controlling actuators in accordance with specified algorithms and rules.
3. Sensors and actuators — devices that collect data on the state of objects and control their operation in response to commands from the control system.
4. Operator Interface - a graphical application that provides operators with information about the current state of the system, the ability to manage and analyze data.

SCADA system functionality:

• Monitoring and visualization — display of process data in real time through graphical interfaces and diagrams.
• Management and control — the ability to remotely control and automate production processes depending on feedback and set parameters.
• Data storage and analytics — accumulation and analysis of historical data to optimize production processes and make management decisions.

Application of SCADA systems:

SCADA systems are widely used in industry, energy, transport, water supply, telecommunications and other industries to ensure effective management and monitoring of distributed objects and systems. They help increase productivity, reduce maintenance costs and improve the overall safety and reliability of production processes.
