A SCADA system consists of a process controller (PLC – Programmable Logic Controller) and a user communication interface (computer running the SCADA software), and since it has a modular structure, various subsequent changes can be made.
This system collects analog (for temperature, pressure, humidity, etc.) and digital signals through specialized sensors on specific parameters: temperature, humidity, pressure, movement, density, etc. The signals are processed by the PLC based on existing programming and then sent to the appropriate actuators that control the start, change, or termination of processes.
