Overview

This project is a SOA(-based) system which utilizes/makes use of microservices, adding new functionalities and ensuring greater scalability.The TFG project currently consists of two different modules integrated into one repository.

The first module is a useful, one client-server system and, since this server Web API uses REST, ensures that a stateless connection is established. Therefore, any client that uses the HTTP protocol will be able to access data. This data comes from the machines and Dashboard information stored in the data base.

On the other hand, however, it's a teoric case where the implementation of the single-source'AAS' is performed on a machine data basis."

Demos

You can find 3 demo files in the project. Just use it as a full example about how to use node-opua or node-opua-coreaas. Of course be sure to change the require statement putting the node-opcua and node-opcua-coreaas module.

• "sample1.js" is a single-file sample showing an AAS sereialitzacion example.
• "sample2.js" is a single-file sample where there ara implemented AAS serialitazcion with node-opcua in such a communication method.
• "sample3.js" is a single-file sample showing an AAS based on the example shown in this document.

Getting started

Project Ionic and Backend

To use this project you only need to decompress the following packages:

Name	Type	Dependencies
discomcloud-ionic	client	Ionic v3
discomcloud_backend_apirest	backend	Microsoft.AspNet.WebApi v4.0.30506.0

Do not remove the node_modules folder, if it does not exist, you will need to install al dependenies.

Project AAS

$ mkdir my-project
$ cd my-project
$ npm init

After that, you can install node-opcua or node-opcua-coreaas as dependency using the following command:

$ npm install node-opcua --save

If only node-opcua-coreaas, is not necessary node-opc-ua, this extension has already included this in its dependencies.

$ npm install node-opcua-coreaas --save

install AAS project f

rom source

 $ git clone https://github.com/manujose94/ETSINF-TFG.git
 $ cd node-opcua
 $ npm install

Running

In the root folder project:

Sample	Command
sample1	npm run sample1
sample2	npm run sample2
sample3	npm run sample3

Minimum nodejs requirement

• nodejs version 6.10 or above

Test

When one sample is launched it shows the information in the terminal:

Server is now listening... ( press CTRL+C to stop) 
port 26544 
the primary server endpoint url is:
 opc.tcp://LAPTOPLL2T36MU:26544/ua/resource

Add a server with addres that shows it:

OPC UA client software: UA Expert

Problems

Exist some problems with the Openssl version when installing dependencies, in this case copy&paste node_modules folder ins root folder into the project.

Copy node_modeles folder into discomcloud_sitenode_backend_apirest\coreAAS\
