7/26/2026PLC & IoT Integration: Data Acquisition & Edge Computing in Industry 4.0
Getting PLC data to cloud is no longer optional. Covers OPC UA, MQTT, edge gateway deployment practices.
Option 1: OPC UA Server Direct to Cloud
Siemens S7-1500 has built-in OPC UA Server; configure security policy to connect directly to AWS IoT SiteWise, Azure IoT Central.
Option 2: Edge Gateway Protocol Translation
For legacy PLCs without OPC UA, deploy edge gateways (Advantech, Moxa, Siemens IOT2050) for Modbus/Profibus→MQTT translation.
Edge Computing: Local Preprocessing Reduces Cloud Bandwidth
At gateway: downsampling, anomaly detection, statistical aggregation; upload only anomalies + hourly stats, >90% bandwidth savings.
