HMI and SCADA solutions for real-time visibility and control
See what is happening on every line, as it happens. We design, build and modernise HMI and SCADA systems that give operators clear control and give managers live data they can trust.
Signs your SCADA is holding you back
SCADA is often the oldest software in the plant. It keeps running, so it gets left alone, until it stops the plant from moving forward.
- Your SCADA version is out of support, or the people who built it have left.
- Screens can only be viewed in the control room, not on the floor or on a phone.
- Operators face alarm floods and miss the alarms that matter.
- There is no reliable history, so trends and root-cause analysis depend on memory.
- Licence costs make it expensive to add screens, users or tags.
- Production data stays inside SCADA and never reaches reports, MES or ERP.
- What We Deliver
Everything you need from a modern SCADA
SCADA & HMI development
New systems designed around your process, for desktop, web and mobile.
Operator-centred screens
Clear, consistent screens based on high-performance HMI principles (ISA-101), so abnormal situations stand out.
Alarm management
Rationalised, prioritised alarms following ISA-18.2 practice, with notifications to the right people by email, SMS or voice call.
History & trends
Reliable time-series history for trends, investigations and compliance, using the Ignition historian or Canary.
Reports & KPI dashboards
Automatic shift, production and energy reports, plus dashboards for every level.
Multi-PLC connectivity
Siemens, Rockwell (Allen-Bradley), Modbus and OPC UA devices brought into one system.
Redundancy & security
High-availability architecture, role-based access and secure remote access.
PLC programming & support
PLC changes and troubleshooting for Siemens and Rockwell systems as part of your SCADA project.
- SCADA Modernisation
Move off legacy SCADA with minimal disruption
Older SCADA platforms get harder to maintain, expand and connect to MES or analytics. We help you move to Ignition in planned stages, keeping what works and improving what doesn’t. A migration is also the right moment to fix alarm floods, clean up tag names and make screens usable on any device.
01
Assess
We audit your architecture, screens, tags, scripts and dependencies.
02
Plan
We agree the migration plan, risks, cut over strategy and rollback options.
03
Convert
We migrate tags, alarms, historical data and databases.
04
Rebuild
Screens are redesigned for web and mobile, not just copied across.
05
Cut over
Parallel running and phased switchover, scheduled around production.
06
Support
A hypercare period after go-live, training for your team and ongoing support.
- Where this fits in your journey
SCADA is the foundation for everything that follows
A modern SCADA gives your plant live visibility, the “See” step of the journey. Once that data is reliable, it can feed MES for production execution and analytics for continuous improvement.
- Frequently Asked Questions
HMI and SCADA: common questions
What is the difference between HMI and SCADA?
An HMI (human-machine interface) is the screen an operator uses to monitor and control a machine or process. SCADA (supervisory control and data acquisition) connects many machines and HMIs across a plant or site, and adds alarms, history, reporting and central control.
Can you work with our existing PLCs?
Usually, yes. We connect to Siemens, Rockwell (Allen-Bradley), Modbus and OPC UA devices, and many others, without replacing your control hardware.
How long does a SCADA migration take?
It depends on the size of the system. A single area can take a few weeks; a plant-wide migration is usually phased over several months. The assessment gives you a realistic timeline.
Can we migrate without stopping production?
In most cases, yes. We run the new system alongside the old one, switch over in phases during planned windows, and agree a rollback plan in advance, so disruption is kept to a minimum.
Why do you recommend Ignition?
Ignition is web-based, runs on standard IT servers and is licensed by server rather than by screen or tag, which makes it practical to grow. It also connects easily to databases, MES and cloud platforms. We recommend it when it fits your needs, and we’ll tell you if it doesn’t.
Do you provide support after go-live?
Ignition is web-based, runs on standard IT servers and is licensed by server rather than by screen or tag, which makes it practical to grow. It also connects easily to databases, MES and cloud platforms. We recommend it when it fits your needs, and we’ll tell you if it doesn’t.
