SCADA and IoT: The Future of Industrial Monitoring
Video coming soon -- subscribe to EDWartens YouTube
The boundaries between traditional SCADA systems and Industrial Internet of Things platforms are rapidly dissolving. This convergence is creating new architectures, new capabilities and new career opportunities for automation engineers who understand both worlds.
Traditional SCADA systems operate in a closed, hierarchical architecture following the Purdue model. Field devices connect to PLCs, PLCs connect to SCADA servers, and SCADA servers present data to operator workstations. IoT introduces a flatter, more flexible architecture where devices can communicate directly with cloud platforms.
Key enabling technologies include MQTT, a lightweight messaging protocol ideal for IoT communications; OPC-UA, which provides secure, platform-independent data exchange; and edge computing, which processes data close to the source before sending summaries to the cloud. Together, these technologies extend SCADA capabilities beyond the plant floor.
Cloud-based SCADA and IoT platforms from Microsoft Azure, AWS and Google Cloud enable remote monitoring of distributed assets, advanced analytics using machine learning, and enterprise-wide visibility across multiple plants. At EDWartens, our Industrial IoT training modules prepare you for this converged future where OT skills meet IT capabilities.
