What Is SCADA Integration?

SCADA integration is the process of connecting industrial machines, PLCs, sensors, RTUs, databases, and software systems into a centralized monitoring and control platform.

SCADA allows industries to collect real-time operational data from machines and display it on centralized dashboards for monitoring, control, and analysis.

SCADA stands for:

• Supervisory
