This data is then used to monitor processes, detect anomalies, and make informed decisions to optimize performance and ensure safety.

At the heart of a SCADA system are programmable logic controllers (PLCs) and remote terminal units (RTUs). PLCs are small, rugged computers that are designed to control specific processes, such as the operation of a pump or the movement of a conveyor belt. RTUs, on the other hand, are typically located in remote locations and collect data from sensors and other devices. This data is then transmitted back to the central control system, where operators can monitor and control the processes. The main functions of a SCADA system include data acquisition, monitoring, control, and alarming. Data acquisition involves collecting data from various sensors and devices. Monitoring involves displaying this data to operators in a user-friendly format. Control involves sending commands to PLCs and other devices to adjust processes. Alarming involves alerting operators to potential problems, such as equipment failures or process deviations. SCADA systems have become indispensable in modern industrial operations, providing operators with the tools they need to monitor and control complex processes, improve efficiency, and ensure safety. However, they also present significant cybersecurity challenges, which we will explore later. The main keyword here is SCADA, we must understand its value and importance.
