Source cover for deploying SCADA and IoT over an existing Ethernet LAN — Published technical article; acceptance metrics and the factory name require separate approval before becoming an official reference.

SYSTEM PATH

Architecture described by the public source

PLC / Ethernet switch -> Modbus TCP or OPC UA -> iNut OPC / iNut PC edge -> web SCADA, Email/Telegram.

Problem: The plant already has an Ethernet switch but needs PLC data, real-time monitoring, and alerts without rebuilding its signal network.
Architecture: PLC / Ethernet switch -> Modbus TCP or OPC UA -> iNut OPC / iNut PC edge -> web SCADA, Email/Telegram.
Deployed layer: iNut OPC · iNut PC · Modbus TCP · WiFi Mesh/RS485 when more field points are needed
Described outcome: Leverage the existing LAN and move data and alerts into an edge layer without replacing the whole cable system.
