Expert Software Development for PLC, SCADA & HMI Systems
PLC & Automation Software Development Services
Whether you’re installing new machinery, upgrading legacy equipment, or scaling your production line, solid software makes it all run smoothly.
At ECS, we design and deliver robust, efficient software for PLCs, HMIs, SCADA systems and wider automation processes. Our job is to simplify the complex, streamline your operations, and keep your systems running safely and reliably, shift after shift.
Bespoke PLC Programming and Automation Software Solutions
There’s no such thing as one-size-fits-all when it comes to industrial software.
Our engineers develop custom control logic and intuitive interfaces for:
- New equipment and production lines
- Upgrades to existing PLCs and HMIs
- Line reconfigurations and system extensions
- Machine safety systems and interlocks
Whether you’re using Siemens, Rockwell, Mitsubishi, Omron, or another major brand, we can build and implement code that works for your plant, not against it.
What We Develop
Everything is tailored, documented, and tested thoroughly, because downtime isn’t an option.
We deliver complete automation software solutions, including:
- PLC programming (Siemens, Allen-Bradley, Mitsubishi, Omron, Schneider)
- SCADA and HMI configuration
- Data logging, alarming, and recipe systems
- Changeovers and line sequencing
- Communication between machines and upstream/downstream systems
Part of a Bigger Picture
Control panels are often one part of a bigger challenge. That’s why we don’t just build a box and walk away.
As part of ECS, we also offer:
- PLC programming and automation software
- Full installation and commissioning
- Remote support with ECS Connect
- Ongoing optimisation and upgrades
That means better results, fewer headaches, and one trusted partner throughout.

Why Choose ECS for Software Development?
When it comes to writing PLC and automation software, we bring more than just code.
Tailored to Your Plant and Process
Every line is written with your machinery, operators, and production goals in mind.
Platform Expertise Across Major Brands
Siemens, Rockwell, Omron, Mitsubishi — we know them inside out.
Clear, Structured, and Well-Documented Code
So future engineers can understand and maintain it, not just the one who wrote it.
FAQs: Automation Software
What brands of PLCs do you work with?
We regularly develop software for Siemens, Allen-Bradley (Rockwell), Mitsubishi, Omron, and Schneider systems. We also integrate across mixed-platform environments.
Can you modify or troubleshoot existing code?
Yes — we can review, improve, or completely rework existing PLC and HMI programs to make them more efficient, compliant, or easier to maintain.
Do you offer remote support?
Yes — with ECS Connect, we can remotely access PLCs and HMIs to diagnose and fix issues without waiting for an engineer on-site.
Can you develop software for legacy systems?
We can often support or upgrade older systems. If it’s no longer supported by the manufacturer, we’ll help you transition to something more modern.
Is your software tested before going live?
Always. Every program we deliver is fully bench-tested and simulated before commissioning to minimise downtime and risk.
