WEL.DO - The HMI

Smarter interaction. Stronger connection.

We are excited to introduce WEL.DO, a complete departure from our Classic CEMAS HMI. Designed with Dart and based on the OPC UA communication protocol, this new generation operator panel reflects our ongoing mission to make standard machines more accessible, efficient, and innovative.

Key Features

  • Unified Interface. Streamlined interaction across all standard machines, with a clean and consistent design system.
  • Centralized Translations (One4All). Every new language is instantly available across the entire project — no duplication, no delays.
  • Continuous Improvement. Each software release brings new features, bug fixes, and performance enhancements.
  • Smart Documentation Access. Help is always one click away. Through the integrated [?] button or the Machine Diagnostics > Support page, users can access a QR code or direct link to the latest multilingual documentation — already available in Italian, English, German, Spanish, Turkish, Brazilian Portuguese, Chinese, and French.

Why a New HMI?

WEL.DO was developed to tackle key Industry 4.0 challenges: machine interconnection, localized interfaces, and streamlined user experience. It’s not just a redesign — it’s a new way of thinking.

Modern Development Approach

By integrating GitLab for versioning and project standardization, we’ve improved transparency, collaboration, and accountability. With full support for CI/CD, even a small translation fix becomes instantly available with the next release — across every compatible machine.

Experience WEL.DO

Where is WEL.DO? Right there! That is, if you choose to adopt any CEMAS standard machine into your own production process. An unified experience, yet extremely adaptable and optimizable to your own configurations and tooling features.

Too good to be true? Watch WEL.DO in action and see how it is redefining interaction in industrial automation.
