OPCUA-Local-Discovery-Server-Example

It's a example project that implements OPCUA LDS in node.js.

We have created a Java client that requests registered servers from LDS.

We have created several servers, in different languages, that register with LDS.

• Client: Java Client in Java
• LDS: Local Discovery Server in Node.js
• ServerNode: Server in Node.js
• ServerCs: Server in C#
• ServerC: Server in C

We also tried without success:

• ServerPython: python-opcua but Issue 1 Issue 2
• ServerMilo: Eclipse Milo

Dependencies

• For LDS and ServerNode: node-opcua
• For Client: UA-Java-Legacy
• For ServerCs: UA-.NETStandard, Dotnet
• For ServerC: open62541

Start project

• LDS

  > cd LDS

  > npm install

  > npm run dev

• ServerNode

  > cd ServerNode

  > npm install

  > npm run dev

• ServerCs

  > cd ServerCs\bin

  > ServerCs.exe

  Or

  • Open ServerCs\ServerCs.sln on Visual Studio (Require .NET Framework 4.6.2 Developer Pack)
  • You can edit LDS default port inside Server\ServerCs.cs

• ServerC

  On linux

  > cd ServerC

  > gcc -std=c99 -UA_ENABLE_DISCOVERY ServerC.c open62541.c -o ServerC

  > ./ServerC

  On Windows

  > cd ServerC\Release

  > ServerC.exe

  Or

  • Open ServerC\ServerC.sln on Visual Studio
  • You can edit LDS default port inside ServerC\ServerC.c

• Client

  > cd ClientOPCUA_LDS

  > java -jar ClientForLDS.jar

  Or

  • Import ClientOPCUA_LDS project on Eclipse (Eclipse -> Import -> Existing Projects into Workspace)
  • Import UA-Java-Legacy stack into Workspace
  • Right click on the project "ClientOPCUA_LDS" and choose Properties.
  • Select Java Build Path -> Projects -> Add and select the stack project (opc-ua-stack)

Copy the LDS endpoint url inside Client for start scan.
