In this article, Victor share with us how to work with Extension Objects in Node-RED.

Extension Objects are a powerful feature in OPC UA that allow you to define custom data structures.

They are often used to encapsulate complex data types that do not fit into the standard OPC UA data types.

OPCUA For NodeRed provides a way to work with these Extension Objects in a powerful way.

This tutorial will guide you through the process of reading and writing Extension Objects in Node-RED using the OPCUA Client nodes.

Revisiting NodeIds and Browse Paths in OPC UA in @opcua/for-node-red​

In the world of OPC UA, NodeIds and Browse Paths are fundamental concepts that enable efficient navigation and interaction with the address space of an OPC UA server. In this article, we will explore these concepts in depth, focusing on their practical applications within the @opcua/for-node-red module.

🔧 Mastering NodeIds in OPC UA: Power, Pitfalls, and Practical Alternatives

NodeIds are at the heart of OPC UA – they’re the backbone for identifying and addressing nodes such as Variables or Objects in the OPC UA server’s address space. Whether you’re reading values, writing data, calling methods or subscribing to events, NodeIds are the key that unlocks access.

But while powerful, they aren’t without limitations.

A Reflection of Industry Excellence In the heart of major industrial advancements, this story of OPC UA for Node-RED unfolds – a narrative deeply rooted in real-world applications and transformative solutions.
