INTEGRATION MATRIX · SERVICES
The Integration Matrix
We work across both sides — the technology on your factory floor, and the business systems that depend on it. Every project is independently assured from day one.
Information Technology
Data Integration & Databases
Your SCADA, MES, ERP and QA systems all hold data — but none of them talk. We build real-time data pipelines that bridge floor data directly to enterprise systems, giving every layer a single version of the truth.
.NET Application Development
C# dominates UK industrial software. We build production-grade .NET solutions that are clean, documented, and handed over — Blazor, ASP.NET Core, SignalR, Power BI and Azure DevOps.
Rust Application Development
Memory corruption in a safety-critical service is a production stoppage. Rust eliminates that class of vulnerability without sacrificing performance — the right language for systems that cannot afford to fail.
Python Application Development
You're sitting on years of SCADA historian data. Python turns it into predictive maintenance models that flag failures weeks early — 18-month payback is typical.
C / C++ Development
The SCADA server from 2007, the PLC logic nobody dares touch, the firmware whose author retired — all C or C++. The risk isn't age, it's that every modification is a gamble.
IT Emulation & Digital Twin
Defects found on the factory floor cost ten times more than on a laptop. Digital twin moves testing out of the live environment — before a single panel is installed.
Frontend & HMI Technologies
FE 04B
A bad operator interface causes mis-reads, missed alarms and operational risk. A good one is invisible. We build for the operator, not the developer's portfolio.
Operational Technology
SCADA
Supervisory Control & Data Acquisition
Downtime costs $125k/hour (ABB, 2023). Two-thirds of manufacturers experience it monthly. Most react hours after a fault starts because there's no live visibility.
PLC Programming
Programmable Logic Controller
Undocumented Ladder logic causes more stoppages than hardware failures. Unplanned OT downtime costs the world's 500 largest manufacturers $1.4 trillion annually — 11% of revenue (Siemens, 2024).
MES
Manufacturing Execution System
Without MES, you're losing 5–15% capacity to invisible waste. Paper travellers, manual entry and verbal handovers lead to compliance failures and missed OEE targets every shift.
WMS
Warehouse Management System
Manual warehouses achieve 85–90% accuracy; WMS delivers 98–99% — and 150–200 picks/hour vs 75–100 manually. That's the difference between reliable fulfilment and expensive safety stock compensation.
Maintenance & Ongoing Support
Periodic Service Contracts & Reactive Support
Downtime costs $125k/hour. Predictive maintenance cuts unplanned stoppages by 50% and costs by 40%. Most in-house teams can't cover every platform.
Building Management
Building & Energy Management Systems
Most buildings waste 20–40% on systems running full-output when nobody's there. Lighting, HVAC, access and energy are all separate — none talking.
Small Automation & Prototyping
Quick-Fix OT Solutions // £3,000 – £5,000
Not every problem needs a full SCADA rollout. Sometimes you just need one fix, one automation, one bottleneck removed — quickly and at a price that needs no board approval.

and many others...
No retainer. No obligation. Just answers.
Most enquiries get a qualified response within 2 hours — often the same day.
When you hire a supplier, you should get what you paid for. We hold vendors accountable from contract to commissioning — so you receive what was agreed, not what was convenient to deliver.
Advice on integration
We review vendor contracts before signature — ensuring deliverables, criteria, timelines and penalties are clearly defined and enforceable. Ambiguous scope is the primary cause of failure.
All functional and non-functional requirements captured, unambiguous, testable and traceable to contract. Gaps surfaced before build, not after delivery.
Independent review of architecture, integration, cybersecurity, data flows and technology choices. Red flags issued in writing before build proceeds.
Monitor progress against milestones, track issues and risks, verify design decisions are honoured during build. Change control enforced throughout.
Structured test execution against agreed test plan — functional, integration, data integrity, security, performance and throughput validation. Each test documented with pass/fail evidence.
Failures raised formally with documented defect reports. We track resolution, verify fixes, re-test until the gate closes. Nothing passes on promise — only on evidence.
Final validation in the live environment — repeatability, stability, alarm management, failover and operator acceptance. Payment withheld until every criterion is independently verified.
Complete handover pack: as-built docs, test evidence, open issue log, architecture, operator guides and maintenance procedures. You own a fully documented system — not a black box.
Downtime, quality escapes, manual workarounds — the losses are real, but invisible. The technology to fix them exists. What's missing is the engineering to deploy it correctly.

Questions
Automation, MES & PLC — frequently asked
Do you provide industrial automation services in the East Midlands?
Yes. IT-to-OT is based in Nottingham and works across the East Midlands — Nottinghamshire, Derbyshire, Leicestershire, Lincolnshire, Northamptonshire and Rutland — as well as throughout the UK. We cover PLC and SCADA engineering, MES and WMS implementation, motion control and drives, and data integration.
What is the difference between MES and WMS?
A Manufacturing Execution System (MES) manages and records production on the shop floor — orders, quality parameters, OEE and traceability. A Warehouse Management System (WMS) manages stock and movements — receiving, put-away, picking, cycle counts and dispatch. We implement both and integrate them with your ERP and PLC layer.
Can you support and repair our existing PLCs and SCADA systems?
Yes. We maintain and repair PLC, SCADA, HMI, historian and industrial network infrastructure across Siemens, Allen-Bradley/Rockwell, Mitsubishi, Schneider, Omron and Beckhoff platforms, including older and obsolete systems. Breakdown response and planned service contracts are both available.
Do you offer independent project management for automation projects?
Yes. As a vendor-neutral third party we work for the client, not the supplier. We help with requirements, planning, supplier oversight, test protocols and independent verification so a project delivers what was agreed, first time.
How quickly will you respond to an enquiry?
We aim to respond within one working day. For live production faults, use the emergency response route on our maintenance page.
Can you connect our factory-floor data to dashboards and business systems?
Yes. We integrate PLCs, SCADA, databases and ERP using OPC UA, REST APIs and SQL, and build dashboards and automated reports so managers see live, accurate operational data. Our BI Department service covers reports, dashboards and data agents.
Do you work with small and medium-sized businesses?
Yes. Alongside larger programmes we offer fixed-price quick-fix automation for a single bottleneck, typically scoped at £3,000–£5,000 and delivered in 2–4 weeks, so smaller firms can start with one measurable win.
Do you provide OT cybersecurity for manufacturing and industrial plants?
Yes. Through our partnership with MON5 (mon5.eu) we deliver OT cybersecurity for manufacturers and critical infrastructure — passive device discovery, vulnerability assessment with CVE and EPSS scoring, ML-enriched anomaly detection, and NIS2 / IEC 62443 reporting. We handle UK sales, installation, configuration and ongoing support, so your plant is protected without stopping production.
What is OT cybersecurity and why does my factory need it?
OT (Operational Technology) cybersecurity protects the industrial control systems that run your plant — PLCs, SCADA, HMIs, sensors and networks — from cyber attacks. Unlike IT security, OT security must not disrupt production. We use passive, non-invasive monitoring to map every device, identify vulnerabilities and detect anomalies in real time, keeping your manufacturing operation compliant and resilient.
Are you NIS2 and IEC 62443 compliant?
We align your OT environment to NIS2 and IEC 62443 frameworks using the MON5 platform. This includes asset inventory, vulnerability management, network segmentation visibility, anomaly detection and exportable audit evidence. Our engineers configure the platform to your specific compliance targets and operational reality.
