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:

• Manage multi OPC-UA server and multi NodeID
• Support anonymous authentication, username/password authentication.
• 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

How to

Software Requirements

• MQTT broker
• Node.js
• .NET Framework 3.5 or above

Installation

Windows:

1. Download OPC-UA Client for Windows from Release Table.

2. Double click the installer to launch the installer to install it to the machine.

Linux:

1. Download OPC-UA Client for Linux from Release Table.

2. Launch the installer to install it to the machine.

Configuration

EdgeSense OPC-UA client can manage multi OPC-UA setting and multi NodeID, below settings are default after OPC-UA client installation.

{
    "OPCUA_Server":[
        {
            "Name": "opcua-server-1",
            "endpointUrl":"opc.tcp://opcua-server-1:66666",
            "userIdentity": {
                "userName": "admin",
                "password": ""
            },            
            "NodeIDList":[{"NodeId":"node-id-1","Name":"node-name-1", "Type":"v", "Interval":2},
                          {"NodeId":"node-id-2","Name":"node-name-2", "Type":"v", "Interval":2},
                          {"NodeId":"node-id-3","Name":"node-name-3", "Type":"v", "Interval":2}
                        ]

        },
        {
            "Name": "opcua-server-2",
            "endpointUrl":"opc.tcp://opcua-server-2:66666",
            "userIdentity": {
                "userName": "admin",
                "password": ""
            },            
            "NodeIDList":[{"NodeId":"node-id-4","Name":"node-name-4", "Type":"v", "Interval":2},
                          {"NodeId":"node-id-5","Name":"node-name-5", "Type":"v", "Interval":2},
                          {"NodeId":"node-id-6","Name":"node-name-6", "Type":"v", "Interval":2}
                        ]

        }
    ]
}

Name

• Assign name for OPC-UA server.

endpointUrl

• Assign OPC-UA Server Endpoint URL , format is opc:tcp://hostname:Port/  , hostname also can use ip address.

userIdentity

• Assign username and password for OPC-UA server security check.

NodeIDList

• NodeId: Assign node ID you'd like to monitor.
• Name: Assign node name you'd like to show for the node.
• Type: Assign node type: "v" is Number, "bv" is Boolean, "sv" is String.

• Interval: Assign node data subscribe/update interval in seconds.

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.

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.
