Advantech Robotic Suite/OPCUAClient Node
Contents
Brief
The OPC Unified Architecture (UA), released in 2008, is a platform independent service-oriented architecture that integrates all the functionality of the individual OPC Classic specifications into one extensible framework.
OPCUAClient Node is a ROS2 node, it can be set to subscribe data form OPCUA server and provide ROS2 DDS topic for user to subscribe, user can quickly receive OPCUA data and do the post data process, for example data parse/store/analysis etc. Below chapter will introduce you about how to use OPCUAClient Node.
