What are the key components of a SCADA system?

Key Components of a SCADA System

A SCADA (Supervisory Control and Data Acquisition) system typically consists of the following key components:

1. RTUs (Remote Terminal Units): These are devices installed at remote locations to collect data from sensors and equipment.
2. PLCs (Programmable Logic Controllers): PLCs are used to control processes and equipment based on the data collected by RTUs.
3. HMIs (Human-Machine Interfaces): HMIs provide a user-friendly interface for operators to monitor and control the SCADA system.
4. Communication Infrastructure: This includes various communication protocols and networks that enable data exchange between RTUs, PLCs, and HMIs.
5. SCADA Software: The software component that collects, processes, and presents data from the various system components for monitoring and control.
6. Historian Database: This component stores historical data for analysis, reporting, and compliance purposes.

These components work together to allow operators to remotely monitor and control industrial processes in real-time, ensuring efficiency, safety, and reliability.
