Eclipse 4diac 3.0 Released — Advancing IEC 61499 for Distributed Automation

Distributed automation systems are becoming increasingly complex, requiring tools that simplify development while ensuring flexibility and scalability. The latest release of Eclipse 4diac 3.0 delivers exactly that — a modernized, open-source automation toolchain designed for IEC 61499-based industrial control systems.

Why This Matters

IEC 61499 is at the heart of the shift toward interoperable and software-defined automation, enabling engineers to design distributed automation systems with reusable, modular components. Eclipse 4diac has long been a cornerstone for developers working with IEC 61499, and version 3.0 takes this to the next level.

Key Highlights of Eclipse 4diac 3.0
  • Reworked Structured Text Editors
    Improved editors and an interpreter make Function Block testing and debugging faster and more intuitive for industrial automation engineers.
  • Enhanced Project Validation and Repair
    Support for incomplete or evolving automation projects ensures smoother development cycles for distributed control systems.
  • Modernized FORTE Runtime
    Upgraded performance, better type handling, and improved compliance with IEC 61499 standards.
  • Introduction of 4diac FBE (Function Block Environment)
    A new build environment simplifying multi-target deployment for industrial controllers and enabling scalable automation solutions.
Why It Is Important for the Automation Community

The automation industry is moving toward open, vendor-independent solutions built on IEC 61499 principles. Tools like Eclipse 4diac empower developers and end-users to adopt interoperable technologies, reduce vendor lock-in, and accelerate innovation across sectors. This aligns perfectly with the vision of software-defined automation and the future of industrial control.
