Node-RED Installing the Windows Software

We will now be installing the Node-RED software on our Windows 10 computer. Node-RED is a powerful and easy programming tool that will allow you to join together hardware devices, APIs (Application Programming Interface), and online services. This joining of information is part of the smart factory. Internet of Things (IoT), Industrial Internet of Things (IIoT), Industry 4.0, and Smart Production are just a few of the other labels that have been applied to this type of technology.
Node-RED Installing the Windows Software

In this series we will be using Node-RED in some of the following ways:
– Connect to our industrial equipment using the Modbus protocol.
– Display Information on a user interface, HMI, or dashboard
– Log information into a database
– View information in the database through spreadsheets such as Excel.
Let’s get started by installing Node-RED.

Supported Node Version for Node-Red

Node-RED requires Node.js to operate.
Node-RED Installing the Windows Software
These are the current versions of Node.js that are supported by Node-RED. We will be using version 12 because it is recommended. This will be a stable environment for our programs.

Node.js Releases

We will be installing version 12 of Node.js.
Node-RED Installing the Windows Software
Currently, this version is in Maintenance mode. Download version 12.20.1 from the following URL:
Node-RED Installing the Windows Software
Since we have a 64-bit windows 10 machine, select node-v12.20.1-x64.msi for the installation download file.

Installing Node.js

Double click on the file you have downloaded to start the installation of Node.js.

The completion message will be displayed after node.js has been installed. Click the Finish button.

Install Node-RED
Installing with npm

To install Node-RED you can use the npm command that comes with node.js:
Open a command prompt in windows and type the following command.
npm install -g –unsafe-perm node-red
Node-RED Installing the Windows Software
The command will install Node-RED as a global module along with its dependencies.

Running Node-RED

At the command prompt type node-red. This will start the program.
