We will now be installing Node-RED on a Raspberry Pi 4 single-board computer. A static IP address will also be given for both the WiFi and Ethernet connections.
The Raspberry Pi has quickly become a fixture in the industrial environment when utilizing the internet of things. (IoT) We will be utilizing this low-cost computer to poll and log information from our PLCs using Modbus and MQTT protocols. Node-RED will be the IoT enabling software that will allow us to utilize this hardware.

There are several reasons why we are using Node-RED. Here are just a few.
- Built on top of the most dependable programming language JavaScript.
- JavaScript is flexible and easy to work with on web browsers, server-side, IoT, IIoT projects, and more.
- Visual flow type interface making programming easy.
- Node will allow JavaScript code to run directly on a computer.
- Node-RED is a free, open-source logic engine.
- Connect to PLC, PAC, Temperature Controllers, Process Controllers using standard protocols.
- Save and read from databases
- Easily make the Internet of Things (IoT, IIoT) industrial solutions.
Node-RED provides the ability for you to quickly create custom control solutions.
