Source cover for deploying SCADA and IoT over an existing Ethernet LAN — The owner approved an anonymous technical-evidence scope from the invoice records; the CMS cover is illustrative, not commissioning photography or an operating KPI.

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.

EVIDENCE BOUNDARY

Approved evidence boundary

This dossier separates the public technical description from the owner-approved scope in the worksheet. The status permits anonymous source evidence only; customer names, KPIs, field photos, and endorsements need separate permission.
