On-Prem AI Server for SAP, PLC, SCADA & AVEVA PI Plants

By Larry Eilson on May 7, 2026

ai-system-integration-sap-plc-scada-power-plant

Plant data is everywhere. Boiler chemistry sits in the BHEL HMI. Steam temperature lives in the Emerson Ovation DCS. Three years of vibration history archives in AVEVA PI. Work orders, spares, and unit availability are buried in SAP PM. Each system answers its own question well, and almost none of them talk to each other in a way an AI can use. iFactory ships an enterprise-grade AI server straight to your plant — pre-configured, pre-tested, racked and ready, with every connector, model, and dashboard pre-loaded. You power it on, connect Ethernet, and the AI starts reading every system within days. Get a quote — and a delivery date.

THE OFFER · WHAT YOU ORDER

Hardware + Software + Integrations — Shipped as One Appliance

This is a physical product, not a cloud subscription. iFactory delivers an enterprise-grade AI server, racked and ready, with the operating system hardened, all eight plant integrations pre-configured, the AI models pre-loaded against your tag dictionary, and the dashboards ready for your operators. You receive it, you power it, you connect it to your network — the AI starts reading your plant within days of unboxing.

ON-PREM APPLIANCE

Enterprise-grade AI server shipped to your plant, racked and pre-configured. NVIDIA GPU, hardened OS, all integrations loaded, models pre-trained. Power on, connect Ethernet, the AI starts reading your plant within days.

PERPETUAL LICENSE

No monthly fees, no per-seat charges, no recurring license costs. Ever. Once purchased, the platform is yours. Future costs are entirely optional and at your discretion.

DATA SOVEREIGNTY

All data lives on your server, behind your firewall. No data leaves your network unless you choose. Compliant with regulator data-localisation rules and corporate IT policy.

SOURCE ACCESS

Modify, extend, and customise the platform freely within your organisation. Your team adapts the system as the business evolves — with or without iFactory involvement.

AI-NATIVE CORE

Predictive maintenance, anomaly detection, NLP-driven work orders — built into the platform from day one. Not bolted on. Not an add-on tier.

The Eight Connected Systems

From Field Sensor to ERP — All Eight Layers, One Integration

The integration package follows the ISA-95 automation pyramid, but reads laterally — every system is a peer in the AI's data graph, not a hierarchy in a corporate diagram. Each system is connected through its native protocol; nothing is bolted on with a screen-scraper.

01
FIELD · LEVEL 1
BHEL Boiler & Auxiliaries

Native Modbus TCP and OPC-UA from the BHEL boiler HMI. Steam temperature, drum level, mill status, ID/FD/PA fan currents, soot blower sequence, and burner tilt — every tag, every second.

Emerson Ovation DCS

OPC-UA secure subscription to the Ovation 4.0 native server. 18,400 I/O points across boiler, turbine, generator, BOP, emissions, and stack monitoring — read-only with full quality codes.

The Architecture

How 1.2 Million Events Per Hour Become One Decision

The integration is not a passive data lake. Each layer transforms the upstream data into something the next layer can act on, with sub-10ms latency end-to-end on the on-site appliance.

L1
Data Acquisition Layer

Eight native protocol adapters running in parallel. OPC-UA, Modbus TCP, IEC 60870, REST, OData, AVEVA PI Adapter, System 1 API, SAP RFC. Each adapter handles its own subscription, quality codes, and reconnection.

Throughput: 1.2M events/hour at peak · 100% lossless buffering

L2
Tag Mapping & Normalisation

Tag identifiers from each upstream system are mapped to a unified asset model — your Asset Framework hierarchy plus engineering units, quality codes, and time-zone normalisation. 99.9% mapping accuracy after calibration on your tag dictionary.

142,000 tags · single canonical asset hierarchy · ISA-95 compliant

L3
Time-Series Engine

On-appliance time-series database with edge retention policy. Hot tier stays in memory for sub-10ms inference. Warm tier on local NVMe for 90 days. Cold tier writes back to AVEVA PI for compliance — your historian remains the system of record.

<10ms hot-tier read · NVMe warm tier · PI cold tier handshake

L4
AI Model Stack

LSTM degradation models, FFT envelope analysers, multi-sensor fusion, and an on-device LLM for plain-language summaries — all running on the local NVIDIA GPU. Inference happens against the unified data graph, not against any single system in isolation.

PdM · anomaly detection · combustion optimisation · NLP work orders

L5
Action Layer · Bidirectional

SAP PM work orders raised through OData. Setpoint candidates pushed back to Ovation on a write-confirm pattern — operator approves before any setpoint moves. Compliance reports exported to PI for audit. Every action logged with operator ID and timestamp.

Write-confirm to DCS · auto SAP work orders · audit-grade logging
Live PI Tag Stream

An Hour in the Feed — What 1.2M Events Look Like in Motion

A representative sample of tags currently streaming from the reference plant into the AI brain. Tag names follow AVEVA PI conventions; values are illustrative. The point is the variety — the AI reads boiler chemistry, turbine vibration, ERP work orders, and dispatch schedule on the same time axis.

Delivery Timeline

From Purchase Order to Live AI — 6 to 12 Weeks

Two timelines run in parallel. The full PO-to-go-live cycle is 6–12 weeks — engineering scope, hardware build, pre-test, ship, install, calibrate, train. The unbox-to-operational cycle, once the appliance lands at your plant, is days — because everything is pre-configured, pre-tested, and pre-loaded before it ships. Most of the 6–12 weeks happens before the appliance ever reaches your site.

Wk 1–2
Engineering Scope Lock

Tag dictionary export from your PI System and Ovation. Functional location export from SAP. Network architecture review. Firewall rules drafted with your IT team. Signed scope document — no scope creep after this point.

Buy vs Subscribe

The Math of Owning Your AI Stack

Cloud SaaS vendors price by the tag, by the user, by the asset, by the API call — and the price grows with your data. iFactory is a one-time capital purchase. Over five years, the difference is significant. Over ten, it is structural.

CLOUD SaaS MODEL
Subscription, per-tag, per-user, per-asset
  • Annual subscription tied to tag count — grows every year
  • Per-user seat fees for engineers, operators, managers
  • Data egress fees from your plant to the vendor cloud
  • Loss of access if subscription lapses or vendor changes terms
  • Your operational data sits on third-party infrastructure
  • Customisation locked behind professional services billing
5-year TCO: continuous, escalating
iFACTORY OWNED MODEL
One-time purchase. Perpetual license. Source access.
  • One-time hardware + license purchase, no recurring fees
  • Unlimited users, unlimited tags, unlimited assets
  • All data on-premises — zero egress, zero exposure
  • Platform stays operational regardless of vendor relationship
  • Your data never leaves your firewall
  • Your team modifies and extends within your organisation
5-year TCO: capital cost, then near-zero
FAQ

What Plant IT & Automation Engineers Ask Before Sign-Off

Does the integration write back to our DCS, or read-only?

Both — your choice per category. By default, all integrations are read-only on initial commissioning. Write-back is enabled only for explicitly approved categories (e.g. soot-blower scheduling, mill load setpoints) and always on a write-confirm pattern — the operator approves the setpoint candidate in the HMI before it executes.

What about plants with PLCs older than OPC-UA?

Common scenario, fully supported. We use a protocol converter or SCADA-layer gateway to bridge legacy Modbus, DNP3, or proprietary serial protocols to OPC-UA at the plant edge. The AI brain only ever sees OPC-UA on its inbound side — protocol diversity is handled before it reaches the AI.

Where does the AVEVA PI System fit — does iFactory replace it?

No, the PI System remains your historian and system of record. iFactory reads from PI for historical model training and writes back compliance-grade data to PI for audit. The AI's hot-tier in-memory cache exists for sub-10ms inference; PI is the cold-tier system of record.

What happens if iFactory the company disappears?

Your platform keeps running. You have the perpetual license, the source code access, the trained models on disk, and the documentation for the integration adapters. Your team — or any qualified integrator — can continue to operate, modify, and extend the platform indefinitely. Vendor independence is the point.
