Simulation of a PLC server that uses the OPC UA communication protocol to simulate temperature sensor data flow

OPC UA Server

This is an example of how to create an OPCUA server using the node-opcua library. The server exposes a single variable, Temperature, which is updated every 5 seconds.

Usage

1. Install dependencies:

npm install

2. Start the server:

npm start

3. Connect to the server using an OPC UA client with the endpoint URL opc.tcp://localhost:26543

Overview

This code creates a new OPCUAServer instance and initializes it with some basic configuration. It then adds a Temperature variable to the server's address space that returns a sine wave value.

Client

To connect to the server, you can use OPC UA client
