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. https://accautomation.ca/do-more-plc-node-red-http-request/ In this series we started using Node-RED in some of the following ways: The entire series can be viewed here: https://accautomation.ca/series/node-red-iot-enabling-software/ Installing the Windows Software https://accautomation.ca/node-red-installing-the-windows-software/ https://youtu.be/xGzH2Hv31WA Modbus RTU / TCP Communication https://accautomation.ca/node-red-modbus-rtu-tcp-communication/ https://youtu.be/yX1w5vcV6cc User Interface - Dashboards https://accautomation.ca/node-red-user-interface-dashboards/ https://youtu.be/8zAG2wXwGOc SQL Database Log https://accautomation.ca/node-red-sql-database-log-modbus-logging/ https://youtu.be/QHjcNj1S_Mo SQL Database Spreadsheet Connection https://accautomation.ca/node-red-sql-database-spreadsheet-connection/ https://youtu.be/Cd3LvhoMaCI Install Node-RED on Raspberry Pi 4 https://accautomation.ca/install-node-red-on-raspberry-pi-4/ https://youtu.be/KleNtxvJkU4 Simple Click Data Logging https://accautomation.ca/simple-click-data-logging-node-red/ https://youtu.be/RmSn4ZSPSmg We will continue with the following: Do-More PLC Node-RED HTTP Request 00:00 Do-More PLC Node-RED HTTP Request 01:12 Do-More REST API Setup 02:20 Do-More Ethernet Security 03:15 Do-More Static IP Address 04:04 Do-More Modbus TCP Server Configuration 04:40 Testing the REST API and Hardware 07:10 Node-Red HTTP Request 10:57 Node-RED Read Write Do-More PLC 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. https://accautomation.ca/
