UADemoPublisher Basics

Introduction

The UADemoPublisher program is a demonstration publisher for OPC UA PubSub.

UADemoPublisher is a console application, running on .NET. It is available for .NET Framework (Windows only), or .NET Core (Windows or Linux). It is available free of charge (does not require a license for QuickOPC or other OPC Labs product).

Note: This page describes a preliminary version (5.55.0.3) of the program; the behavior is subject to change in future versions. This version only support the OPC UA UDP transport protocol mapping (UADP over UDP).

Usage

In order to run the UADemoPublisher, open a command prompt, and switch to the directory that contains the program. You can start the program without any additional parameters. If you are using the .NET Framework version, type UADemoPublisher and press Enter. If you are using the .NET Core version, type dotnet UADemoPublisher.dll and press Enter. In the text that follows, when discussing the command line options, we will be listing the commands simply with the UADemoPublisher at the beginning; remember to use dotnet UADemoPublisher.dll in .NET Core instead.

By default, the UADemoPublisher send messages to IPv4 multicast address 239.0.0.1. This can be changed using the --ConnectionResourceUri (-cru) option (see further below). The published data sets and the way they are published are hard-coded into the program and cannot be changed (for most part).
