Many industrial operations continue to rely on legacy PLCs that can limit system integration, increase maintenance complexity, and introduce operational and cybersecurity risks over time. Modernization offers a path forward — but traditional migration approaches can be time-consuming, resource-intensive and disruptive.

This brochure outlines how Honeywell applies an intelligent, model-based engineering approach to PLC modernization. By combining ControlEdge™ UOC controllers with advanced engineering tools such as iDefine, organizations can automate key stages of migration, reuse existing control logic and standardize engineering workflows across systems.

This approach supports more efficient project execution, reduces manual engineering effort and enables faster deployment while maintaining operational continuity. With built-in cybersecurity features, scalable architecture and lifecycle support, it provides a foundation for long-term modernization and ongoing performance improvement.
