DEMO OPC UA Servers - "OPC UA Knowledge Completion via Graph Embedding and Reinforcement Learning"

This is repository of the DEMO OPC UA-servers used to validate the results of the paper entitled "OPC UA Knowledge Completion via Graph Embedding and Reinforcement Learning". The servers import multiple nodesets copied from the official releases of the OPC Foundation: https://github.com/OPCFoundation/UA-Nodeset

The default port of the servers application are 4840 and can be changed in the configuration file config.yml.

Requirements

• NodeJs : The Backend requires NodeJs and a node global package npm.
• Git
• Dockers: For a container installation, Docker is required. Please refer to the docker documentation for docker installation.

2020-05-18 09:06:18 - [info] | [Dummy Server] : Server is now listening ... ( press CTRL+C to stop)
2020-05-18 09:06:18 - [info] | [Dummy Server] : port 4840
2020-05-18 09:06:18 - [info] | [Dummy Server] : The primary server endpoint url is opc.tcp://LAPLACE.FAPS.UNI-ERLANGEN.DE:4840

The OPCUA server is now accessible at opc.tcp://LAPLACE.FAPS.UNI-ERLANGEN.DE:4840.

Deploy as a Microservice using Docker[Swarm]

You can also deploy as a microservice inside a Docker container:

Step 1: Clone the repo

Step 2: Build the Docker image

docker build -t faps_opcua_demo_server_one .

Step 3: Run the Docker container locally:

docker run -p 4840:4840 -d faps_opcua_demo_server_one

Usage

In order to configurethe server, the file config.yml has to be configured appropriately. For example the following configuration set the default port of the OPCUA server to 4843.

default:
  server:
    port: 4840
    buildInfo:
      productName: "Dummy Dateset Server One"
      buildNumber: "0001"
    ip: "0.0.0.0"
    endpointName: 'OPCUA@Siemens'
    username: 'root'
    password: 'root'
    allowAnonymous: false,
    serverInfo:
      applicationUri: "http://siemens.com/SkillOPCUA"
      productUri: "siemens.com/SP347_Example"
      applicationName: "SP347SkillEngineering@Siemens" 
    serverNodeSet: ["UA-Nodeset-master/DI/Opc.Ua.Di.PredefinedNodes.xml",
    "UA-Nodeset-master/FDI/Opc.Ua.Fdi7.PredefinedNodes.xml", 
    "UA-Nodeset-master/ISA-95/Opc.ISA95.NodeSet2.xml", 
    "UA-Nodeset-master/AML/Opc.Ua.AMLBaseTypes.NodeSet2.xml", 
    "UA-Nodeset-master/AutoID/Opc.Ua.AutoID.NodeSet2.xml",
