We are excited to announce that HELIO 25.3, our third feature release of 2025, is now officially available to everyone. With this new version, you can connect faster, run stronger, and build better.
OPC UA: Connect Faster. Run Stronger. Build Better.
The main highlight of HELIO 25.3 is the major upgrade of our OPC UA connections: Whether you're developing in the IDE, commissioning projects, or running in production, HELIO now connects to OPC UA servers instantly. This improvement comes from listening to our customers and a dedicated team effort across engineering and design.
Your connections will be rock solid now, whether you’re working with controllers with limited resources or with large data trees – even when PLCs disconnect and reconnect. Less waiting. More building. Better results.
