SCADA
A supervisory control and data acquisition system used in industrial sectors such as power, water, manufacturing, and transportation to monitor and control processes and collect operational data.

IoT
A network of physical devices connected to the internet to collect and exchange data.

IoT SCADA
The integration of traditional SCADA systems with IoT technologies to enhance flexibility, scalability, and intelligence in monitoring and control.

IoT SCADA System Architecture

Field Devices (Sensors/Actuators):
Collect data from the environment and control equipment.

Edge Devices / Gateways:
Process and transmit data from sensors to the control system or the cloud.

Communication Network:
Includes industrial networks (Modbus, OPC, MQTT, etc.) and the Internet.

SCADA Server or Cloud SCADA:
Visualizes, stores, and processes real-time data.

SCADA Software:
Provides HMI (Human-Machine Interface), reporting, alarm management, and related functionalities.

Benefits of Integrating IoT into SCADA

1. Enhanced Remote Accessibility:
Data can be monitored anytime, anywhere via mobile devices and web platforms.

2. Advanced Data Analytics:
Integrates AI/ML to predict failures and optimize operations.

3. Easy Scalability:
Allows seamless connection of additional devices without the need to redesign the entire system.

4. Reduced Maintenance Costs:
Enables early fault detection through continuous monitoring and big data analytics.
