An edge data hub for your whole plant — read, store, monitor & control.
iNut Datalogger is a mini-server running right at the edge: it gathers 100+ PLCs and multi-protocol devices into one web SCADA (FUXA), stores data long-term, controls with feedback — and your data stays on-site, not in a rented account on someone else's cloud.
Four "walls" that stall a monitoring project
With a few devices, any approach works. But as the system expands — more PLCs, more sites, more protocols — these are exactly what you run into.
WinCC stops at the 8th PLC
Connections drop, errors appear, you can't add more. Buying extra licenses & hardware gets expensive.
Fear of losing data ownership
A foreign cloud holds your data, charges long-term subscriptions, locks you into the vendor.
Hard to restyle, hard to open APIs
Want to redesign the HMI, or extend API connections to third parties (government API gateways, ERP, external services…)? All blocked — a closed, vendor-dependent system.
Power-sector multi-protocol
Power/hydropower projects need IEC 104, IEC 61850 — something generic Modbus-leaning gateways usually don't emphasize.
Put a "middle layer" between your SCADA and your PLC forest
Instead of making WinCC strain to connect directly to every PLC, place iNut Datalogger as the middle layer: it gathers data from hundreds of PLCs, then re-presents it to WinCC as Modbus TCP/RTU — a protocol WinCC reads with ease.
WinCC connects directly
From the 9th PLC on: flaky connections, failures. You must split the system & lose the big picture.
WinCC ⟷ Modbus TCP/RTU ⟷ iNut Datalogger
iNut Datalogger gathers everything, opening multiple Modbus Slave ports (1502–1507) so other SCADAs can connect too.
Because iNut Datalogger isn't a passive gateway — it's a mini-server running at the edge (64-bit chip, 4GB RAM, 32GB storage), powerful enough to manage many concurrent Modbus sessions and store the data. It supports Modbus RTU and TCP in parallel, converting RTU ➜ TCP.
Even when a project mixes many PLC brands, it all comes back to one place.
The capabilities of an edge data hub

Built-in FUXA SCADA/HMI
A web-based dashboard: gather many devices onto one screen, monitor, alarm — and control ON/OFF, not just view. Includes a FUXA PRO license worth 3.3M₫, free.
Self-hosted — your data
Your own edge server, not a rented account on a foreign cloud. Long-term storage (≥1 year).
Data becomes an asset
Query history, analyze trends, detect anomalies, ready for AI prediction down the road.
Secure P2P link between two sites
A private, encrypted channel — monitor & control the plant remotely and safely, with no leakage outside.
Always online · WiFi + 4G
Auto-switches between WiFi and 4G under several policies (prefer WiFi, prefer 4G, automatic failover…) — the edge server stays online continuously, collecting & controlling without interruption.
Customize the HMI & open APIs · FREE programming
Freely redesign the HMI and connect third-party APIs (government API gateways, ERP, external services…) with JavaScript — easy with ChatGPT/Claude/Gemini. The programming part, we do for free.
Lighting SCADA — monitor, control & leakage-current alarm on one web screen
Built exactly to your single-line diagram: from the main MCCB → 2 lighting lines → each pole, with status feedback and real-time alarms.
The problem
Lighting operated the old way: to switch on/off you go to the panel and flip contactors; to know voltage/current you measure on the spot; most dangerous of all, leakage current is only detected when it's already too late. At the scale of many lines, this is labor-heavy, slow, unsafe — and leaves no data behind.
The solution we built
- PM1125H multifunction meter measures the incoming supply: per-phase voltage/current, total kW — the "health meter" of the whole system.
- LOGO! PLC controls 2 lines (Q1/Q2, MAN/AUTO mode); ON/OFF buttons on the screen write flags M10/M11 down to the PLC.
- I4/I5 feedback (FB1/FB2) reads the actual state of the contactor — not just "commanded" but "actually closed/opened or not".
- I3 leakage-current sensor: detects leakage → the alarm light turns red in real time.
Why it beats the old way
Thanks to secure P2P, view & control from the office or your phone, no need to go to the panel.
I4/I5 feedback answers "I pressed off, but did it actually turn off?".
Leakage current alarms immediately, no waiting for an incident to find out.
Every value and event stored on-site; a foundation for load analysis and operations optimization later.
Replicate it: the model of "supply meter + control PLC + status feedback + alarm, shown on a web SCADA" applies to any switched load — pumps, fans, conveyors, central air-conditioning, substations. With a diagram and one PLC, it can be digitized.

Send us your drawing / system details — we'll build a trial sample SCADA matching that exact system, FREE.
You see your own system actually running in a browser before you decide — more convincing than any ad, and it removes the "I don't have a SCADA programmer" barrier.
Have isolated meters far away? Use iNut RS485 as a "satellite" feeding into iNut Datalogger.
iNut Datalogger is the hub. But not every measuring point needs an edge server. For a single meter or a Modbus RTU sensor sitting off in a corner of the plant or a remote station, iNut RS485 is the lightweight, cost-optimized gateway — reading on the spot and pushing real-time back to the central iNut Datalogger over MQTT/P2P/WiFi Mesh.
💡 Recommended architecture: many iNut RS485 at isolated points → one iNut Datalogger to gather & store → one overall SCADA.
iNut RS485 — Modbus RTU Gateway
- Cost-optimized for 1–4 Modbus RTU slaves
- Real-time status: OK / Timeout / CRC
- Remote config via app · always online WiFi/4G
- Pushes straight to your MQTT — "buy and use"
- Monitor the entire plant with the iNut RS485 WiFi Mesh network
