OPC-UA Client

Introduction

OPC Unified Architecture (OPC UA) is a machine to machine communication protocol for industrial automation developed by the OPC Foundation.

EdgeSense OPC-UA Client

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

Setup a OPC-UA sample server

OPC UA Sample Applications 1.02.msi are available at local server, please paste file's url in File Explorer to copy file.

After installing OPC UA Sample Applications 1.02.msi , launch DataAccess Server. Then, OPC-UA Client can connect to Server Endpoint URLs shown in application.

Configuration

EdgeSense OPC-UA client can manage multi OPC-UA setting and multi NodeID . 

opcua-client.json setting file example:

{     "OPCUA_Server":[         {             "Name": "ARK-OPCUA",             "endpointUrl":"opc.tcp://desktop-2lhi6fa:62547",             "userIdentity": {                 "userName": "",                 "password": ""             },                         "NodeIDList":[{"NodeId":"ns=2;s=1:CC2001?Input2"},                                   {"NodeId":"ns=2;s=1:CC2001?Output"},                                   {"NodeId":"ns=2;s=1:CC1001?Output"}                                 ]         },         {             "Name": "NB-OPCUA",             "endpointUrl":"opc.tcp://nb050904:62547",             "userIdentity": {                 "userName": "",                 "password": ""             },                         "NodeIDList":[{"NodeId":"ns=2;s=1:CC2001?Input2"},                                   {"NodeId":"ns=2;s=1:CC2001?Output"},                                   {"NodeId":"ns=2;s=1:CC1001?Output"}                                 ]         }             ] }

Name

• Assign name for a OPC-UA server.
