Reference architectures
Industrial IoT architectures without opening control to the internet.
How it looks today
Every machine wired to every system.
Four devices and four systems already mean sixteen hand-built integrations. Every new sensor adds one more, and without a manual it takes months of trial and error.
- The same data reaches each system with a different timestamp.
- Replacing a device means redoing its integrations.
01 · Star topology
Unified Namespace (UNS)
Instead of wiring every machine to every system, everything publishes to and reads from a central MQTT broker running on the Edge. Each piece of data has a name and a place: line, machine, variable.
- Adding a machine or a system does not mean redoing integrations.
- SAP, the SCADA and the app read the same data, with the same timestamp.
- Modbus, OPC UA and S7 come in through the same point.
02 · OT security
Separated zones, read-only
For plants where operations will not accept anything that could write to the control layer. The Edge is installed with two network interfaces: one reads the PLC network read-only, the other sends filtered data to the corporate network, always outbound.
- No inbound ports are opened toward the control network.
- Level separation in the style of the Purdue Model (ISA-95).
- The AI proposes; any action on a machine is approved by a person.
03 · Multi-site
Edge per plant, group cloud
For groups with several plants. Each one processes on its Edge and stores locally; only clean aggregates go up to the group private cloud to compare plants, not the raw signal or video.
- Less bandwidth: the summary goes up, not every reading.
- If the internet drops, the plant keeps measuring and syncs when it is back.
- Management sees every plant with the same indicators.
04 · Auto-discovery
Plug in a new sensor and the AI recognizes it.
The iGromi Bridge discovers the devices on the network, finds how to talk to them even without a manual, and the AI proposes what each register measures. A person confirms before the data comes in.
How it works, live
From a plugged-in cable to named data, in four steps.
- 01Protocol sweep
The Bridge walks the network and serial ports and lists the devices that reply.
- 02Parameter search
No manual: it tries speed, parity and address until it talks, and finds the registers without the map.
- 03The AI proposes the map
@igromi proposes which physical variable each register is, and its unit.
- 04A person confirms
You confirm or correct it in the app. Only then does the data come in, named and read-only.
Everything is read-only: discovery never writes to the PLC or the sensor. Example values.

| Multi-site | Management compares several plants | One Edge per plant and a group private cloud |
Where the data lives
Your company decides, depending on the plan.
The same rule in all three architectures: the AI reads, proposes and cites its source; a person decides.
iGromi cloud, separated per company
The shift app: chat, photo and voice records, and AI that answers with its source.
A private, isolated cloud for your company
Adds SAP, ERP and spreadsheets. The AI model runs inside that cloud.
Inside your plant, on Edge or on-premise
Adds PLCs, sensors and cameras. The Edge reads the PLC read-only and keeps measuring offline.
How it looks in the app
The architecture ends in a conversation.
The operator asks in the app and @igromi answers with the PLC value, the SAP order or the shift record, and says where it comes from.
- Chat by area and shift, with photo and voice records.
- Answers with the source of each piece of data.
- Start free, without installing anything in the plant.
Free app in early access. Web available; Android and iOS coming soon.
