SmartFactory OPC Module

SmartFactory OPC Module is a client-server module designed to collect, clean, store, and analyze data from an OPC server for AI-based predictions. This module simulates an OPC server using real-time weather data from the OpenWeather API and implements various security measures to ensure secure communication and data integrity.

Features

• Simulates an OPC server using OpenWeather API data.
• Implements server-side security measures, including identity validation and certificate management.
• Allows for the monitoring, subscription, and modification of OPC node variables.
• Designed for future integration with AI prediction models.

Version History

Version 0.1

• Feature: Created an unsecured OPC server with basic endpoints.
• Details: Uses the OpenWeather API to simulate weather data, mimicking the behavior of an actual OPC server.

Version 0.2

• Feature: Added optional server-side security measures.
• Details:
  • Username Identity Validator: Validates clients based on username and password.
  • X509 Identity Validator: Uses X.509 certificates for client authentication and secure communication.
  • Certificate Management: Manages server and client certificates, ensuring only trusted connections.
  • Security Policies: Implements SecurityPolicy.Basic256 and SecurityPolicy.Basic256Sha256 along with MessageSecurityMode.Sign and MessageSecurityMode.SignAndEncrypt to protect communication.

Version 0.3

• Feature: Added node variables from weather data.
• Details: Variables are created for each weather parameter, with the ability to update them based on frequency or change, using the Prosys OPC UA client.

Version 0.4

• Feature: Enhanced variable management.
• Details: Variables can now be subscribed to, monitored, or edited, with flexible update triggers based on frequency or change.

Getting Started

Prerequisites

• Java Development Kit (JDK): Version 11 or later.
• Maven: For building the project.
• Prosys OPC UA Client: To interact with the OPC server.
• OpenWeather API Key: For accessing weather data (optional).

Installation

1. Clone the repository:

   git clone http://git.addixo.io/sf-group/smartfactory-opc-module.git
   git checkout devhamza
   cd smartfactory-opc-module

2. Build the project using Maven:

   mvn clean install

3. Run the OPC Server:

Usage

• Start the OPC server: Follow the instructions above.
• Interact using Prosys OPC UA Client:
  • Connect to the server using the provided endpoint.
  • Browse and interact with the OPC node variables.

Security Configuration (optional)

• Username Identity Validation: Modify the list of valid usernames and passwords in the configuration file.
• X509 Identity Validation: Manage certificates in the keystore (keystore.pfx). New certificates can be generated using the KeyStoreLoader class.
