Programming OPC UA Servers and Clients with NodeOPCUA

Professional Training

A 3-day training course to learn how to develop OPC UA applications using Node.js and the NodeOPCUA library, focusing on creating practical clients and servers.

Summary

This module focuses on the practical development of OPC UA applications using Node.js and the open-source Node-OPCUA library. Participants will learn to build clients that can connect to servers, browse the address space, read and write data, subscribe to changes, and call methods. They will also learn to create a simple OPC UA server that exposes data and implements basic services. The module emphasizes hands-on experience to enable developers to quickly create their own OPC UA-based solutions.

Objectives

  • Understand the NodeOPCUA library and its capabilities.
  • Develop a basic OPC UA server and client.
  • Implement advanced server features such as security, methods, and events.
  • Create a comprehensive client that interacts with the server.
  • Gain practical experience through hands-on exercises and projects.

Target Audience

This module is primarily aimed at developers (especially JavaScript/Node.js), software engineers, and automation or IT engineers with programming skills who wish to implement custom OPC UA solutions. A basic understanding of JavaScript/Node.js is a prerequisite.
