Do-More PLC Node-RED HTTP Request
Node-RED HTTP Request can be used to read any BRX Do-More PLC memory area. This HTTP (Hypertext Transfer Protocol) communication will only read information from our controller.
The BRX Do-More REST API is used to read information using a URL (Uniform Resource Locator) or web address. We will be using the HTTP request node in Node-RED to read information from our BRX Do-More REST API-enabled controller. Writing using Modbus will also be shown. This will all be done on our Raspberry Pi 4 single-board computer. Let’s get started.
More information can be obtained at our website. This includes all of the links mentioned in this video.

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.
