Making Industry Work – Leveraging OPC UA at Scale
Securely Connect, Manage, and Scale Industrial Devices with OPC UA on FlowFuse
OPC UA has become the gold standard for secure, reliable industrial communication — but deploying and managing it at scale across distributed devices remains a significant challenge for many organizations.
Without the right tooling, teams are left wrestling with complex configurations, inconsistent security policies, and fragmented device management that slows down digital transformation.
By combining the flexibility of Node-RED with enterprise-grade device management, FlowFuse makes it practical to deploy OPC UA connections securely across your entire industrial estate — from a single machine to thousands of endpoints.
In this webinar, Kristopher Sandoval and Etienne Rossignon, creator of NodeOPCUA, walked through how to connect industrial devices using OPC UA in a secure, scalable, and maintainable way — reducing complexity without sacrificing the robustness that industrial environments demand.
Etienne and Kristopher covered:
- What NodeOPCUA is and why OPC UA has become the preferred protocol for secure industrial connectivity
- The common challenges of deploying OPC UA at scale and how FlowFuse + NodeOPCUA addresses them
- How to configure client/server connections securely within FlowFuse
- Managing security certificates and authentication across a fleet of devices — including managed certificate renewal and GDS enrollment
- How the Explore node replaces dozens of manual reads with a single operation, returning the full OPC UA hierarchy as a structured JSON object
- Namespace aliasing for stable, reusable node references across deployments
- Configuration-driven node ID subscriptions — passing arrays of node IDs programmatically instead of selecting through the UI
- A layered security approach: OPC UA certificate management + FlowFuse encryption at rest and in transit + role-based access control
This session is ideal for OT/IT engineers, automation architects, and industrial IoT practitioners looking to modernize their device connectivity strategy and get more from their OPC UA infrastructure.
OPC UA doesn't have to be this complex
If managing connections, certificates, or device configurations is slowing your team down, book a demo to see how FlowFuse and NodeOPCUA make it practical — without the overhead.
