Developed for Developers.

  • Full focus on project success in just a few sprints,
    simply develop OPC UA applications.

OPC UA Client Development

Simply. Develop. Clients.

The powerful client API delivers fast results. And constantly establishes a secure, stable connection to the server. Intuitive from new to calling ReadNode. There is a suitable overload for every case.

Select endpoints with class, connect, create, open and activate sessions. With just one call to Connect.

The necessary libraries and assemblies can be tested for free without registration and are available for download via docs.traeger.de and on NuGet.

Quick. Server. Serving.

Deliver data in style with the elegant server API. Sessions, their authentication and client requests take place in the background.

Define valuable data points, methods, files, messages, alarms, their types and serve them by calling Start.

OPC UA client that subscribes to temperature changes

Fast implementation, seamless integration.

The code snippet demonstrates the effortless setup of real-time data monitoring with minimal effort.

With just a few lines of code, a connection to the OPC UA server is established and a data subscription is set up that reacts immediately to changes and processes them.

The SDK provides powerful features and an incredibly intuitive API that allows developers to focus on what's important: processing and using data.

So simple, so powerful.

The code snippet shows how you can set up a server that provides and manages data in real time with just a few lines of code.

The intuitive API makes it easy to define and dynamically update variables such as temperature – all in a simple, repeatable cycle. Develop robust server solutions that are as efficient as they are reliable and experience a new dimension in industrial data processing.

OPC UA server that simulates temperature changes

More business logic. Less OPC UA.

OPC UA client that interacts with a machine and a file

Simple, precise, powerful.

This code snippet shows how easy it is to read machine parameters, start jobs and retrieve reports – all with minimum effort and maximum efficiency.

Thanks to the clear, elegant API, reading, writing and executing actions becomes an effortless task, allowing developers to focus on the essentials: optimizing workflows and increasing productivity.

Efficient business processes.

The code snippet shows how seamlessly business objects such as machines or reports can be integrated directly into the server.

The clear and intuitive API makes it easy to define methods and data objects while utilizing the full power of OPC UA without being distracted from the actual business functionality.

The result is a solution that is both technically sophisticated and business-focused.

OPC UA server that provides a machine and report

Your machine. Your data. Get it!
