OPC-UA Client
Introduction
OPC Unified Architecture (OPC UA) is a machine to machine communication protocol for industrial automation developed by the OPC Foundation.
Features
EdgeSense OPC-UA Client aims to collect data from OPC-UA Server and control.
Feature:
- Connection with multiple OPC-UA server and multiple Node ID.
- Support anonymous authentication, username/password authentication.
- Support individual node data update interval of subscription.
- Configurable node alias.
- Currently support up-link OPC-UA data to WISE-PaaS , not support down-link from WISE-PaaS.
- Detailed features, please see https://docs.google.com/spreadsheets/d/1hxUJgHvcPYq8f44gmVVmwUCddHhOPBflSRkSKR0H9Q4/edit?ts=5ca2bfc9#gid=348272669

Demonstration
Connect a Unified Automation C++ Demo Server
1. Download Unified Automation C++ Demo Server from https://www.unified-automation.com/downloads/opc-ua-servers.html and install it to the server machine.
2. Launch UaCppServer from Windows Start Menu.
3. Config OPC-UA Client to connect to the Unified Automation C++ Demo Server, Username/Password, Endpoint URL and Node IDs are shown in below.
| Username | Password |
| root | secret |
| Endpoint URL Format | opc.tcp://<Mancine Name or IP>:<Port> |
| Endpoint URL for this Demo |
opc.tcp://Protocol-Converter-GW:48010 |
| Node Nmae | Node ID |
| AirConditioner_1.Humidity |
ns=3;s=AirConditioner_1.Humidity |
| AirConditioner_1.Temperature |
ns=3;s=AirConditioner_1.Temperature |
| AirConditioner_2.Humidity |
ns=3;s=AirConditioner_2.Humidity |
| AirConditioner_2.Temperature |
ns=3;s=AirConditioner_2.Temperature |
4. Edit opcua-client.json to set up client configuration, for example:
{
"OPCUA_Server":[
{
"Name": "OPCUA-UACPP-SERVER",
"endpointUrl":"opc.tcp://Protocol-Converter-GW:48010",
"userIdentity": {
"userName": "root",
"password": "secret"
},
"NodeIDList":[{"NodeId":"ns=3;s=AirConditioner_1.Humidity","Name":"AirConditioner_1.Humidity", "Type":"v", "Interval":2},
{"NodeId":"ns=3;s=AirConditioner_1.Temperature","Name":"AirConditioner_1.Temperature", "Type":"v", "Interval":2},
{"NodeId":"ns=3;s=AirConditioner_2.Humidity","Name":"AirConditioner_2.Humidity", "Type":"v", "Interval":2},
{"NodeId":"ns=3;s=AirConditioner_2.Temperature","Name":"AirConditioner_2.Temperature", "Type":"v", "Interval":2}
]
}
]
}
5. Restart device-opcua-client service from Windows Task Manager.
