• Full life cycle support

The efficiency of STone extends throughout the entire unit life cycle: from design to commissioning and local and remote maintenance.

• Cybersecurity: your security comes first

In an increasingly connected industrial world, cybersecurity is vital. STone integrates the most rigorous market standards to protect your assets against unauthorised access and tampering.

As of today, you can plan the future of your business using STone copilot for programmable electronic controllers

In modern industry, speed and precision are no longer simply objectives, but rather essential requirements. This is why we have integrated the power of generative artificial intelligence into the heart of the STone programming environment.

Our copilot isn’t just a tool - it’s an expert assistant, designed to unleash the potential of your engineers and transform the way your units come to life.

Why choose AI-assisted programming software?

From word to code in seconds

Forget about hours spent writing repetitive lines of code. With copilot, you can simply describe the function you require in natural language, and the AI assistant will instantly generate an optimised draft of code. Whether it’s complex logic or standard configurations, productivity is doubled, allowing you to focus on what really matters: innovation.

Predictive maintenance and intelligent debugging

Downtime is the number one enemy of production. Our Copilot represents a 24/7 technical consultant: it analyses the code, identifies any issues, and suggests immediate solutions to fix bugs. System maintenance has never been easier and faster, slashing operating costs.

A bridge between experience and innovation

Technical knowledge is a precious commodity. AI facilitates the transfer of skills, helping junior programmers quickly conquer the learning curve and offering more senior programmers constant support for more tedious tasks.

Quality and standardisation, without compromise

Human error is a thing of the past. AI ensures that every line of code meets the highest standards of quality and consistency. The result? More robust systems, easier to read, and ready to scale globally.

The future of HVAC/R programming is here

Don’t just sit back and watch the market move on. Adopting programming software such as AI-powered STone means choosing competitiveness, sustainability, and operational excellence.
