Equipment sold overseas is equipment you cannot walk up to. Cloud monitoring closes that gap: live status, historical trends and alarm push, so a fault is diagnosed before an engineer books a flight. Data collection runs on the PLC side over OPC UA/MQTT, so no change to the control logic is required.

Typical applications — remote plant supervision across sites · after-sales support for exported machinery · unmanned pump and water stations · energy and production data collection

What we deliver — gateway and data collection setup · cloud platform configuration · mobile and browser dashboards · alarm push rules · historical data and reporting
