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.
Topic definition
The topic of OPCUA node data are defined as below:
/adv/opcuaclient
Message definition
The messages definition of SUSI node is defined in below link:
http://ess-wiki.advantech.com.tw/view/Advantech_Robotic_Suite/Advantech_ROS2_Data_Format
Configuration
To config OPCUA node settings, please refer the guide: http://ess-wiki.advantech.com.tw/view/OPC-UA_Client
Message update
The message is updated periodically, you can use ROS2 utility to verify the data update:
Subscribe Sensor using ROS2 utility
Step1. Setup ROS2 environmant variables:
$ source /opt/ros/${ROS_DISTRO}/setup.bash
Step2. Setup OPCUAClient Node message:
$ source /usr/local/Advantech/ros/${ROS_DISTRO}/include/edge-converter-ros2/adv_msgs/install/local_setup.bash
Step3. List all topics:
$ ros2 topic list
output:
/adv/parameter_events /adv/opcuaclient /parameter_events /rosout
Step4. Subscribe node data
$ ros2 topic echo /adv/opcuaclient
output:
--- sensor: OPCUAClient/OPCUA-01/Node/Temperature type: v bv: false v: 25.713000000426085 sv: '' ts: 1677661555546 --- sensor: OPCUAClient/OPCUA-01/Node/Humidity type: v bv: false v: 59.999999999653745 sv: '' ts: 1677661556561 ---
Sample Client
This session describe how to subscribe OPCUA node data by node's topic.
Node.js
The program rclnodejs_edge_data_client is a node.js example for user to learning how to use rclnodejs client to subscribe OPCUA node's data. Please follow below steps to run the program, when the program launched, it will subscribe OPCUA node's sensor data and print the data in the console screen.
Steps - Subscribe Sensor
Step1. Setup ROS2 environmant variables, replace ${ROS_DISTRO} with your ROS2 distribution (foxy, humble) to run this command:
$ source /opt/ros/${ROS_DISTRO}/setup.bash
Step2. Setup OPCUAClient NodeS message:
$ source /usr/local/Advantech/ros/${ROS_DISTRO}/include/edge-converter-ros2/adv_msgs/install/local_setup.bash
Step3. Go to node.js OPCUA sample path:
