Node-RED is a visual programming tool for connecting physical hardware devices, APIs, and online services together as part of the Internet of Things. It was originally developed by the IBM Emerging Technology Services team and is now a part of the OpenJS Foundation. Node-RED’s low-code, drag-and-drop interface makes it easy to create complex data flows without writing code. Node-RED is an open-source tool and there is a huge assortment of downloadable nodes available online at https://flows.nodered.org/. There you’ll find nodes for various tasks, including input/output, data processing, logic, and social media functions.
But what can Node-RED do? Node-RED has had millions of downloads and is being applied in many applications, both commercial and industrial. One example is an OEM who makes cotton gins. This OEM used low-code Node-RED programming to connect weather data with their machinery’s operations. Their system adjusted processes based on real-time humidity and rain forecasts vital to the cotton industry and even sent text alerts to operators. The Node-RED platform is extremely flexible and offers virtually unlimited possibilities, whether used for simple communication or for complex data analysis.
Due to the growing popularity of this tool, many of our PLCs now support Node-RED implementations. These PLCs allow you to take full advantage of Node-RED’s capabilities while at the same time saving you on equipment costs. The posts below contain articles, videos, etc. to help you learn more about Node-RED and how it is utilized in industrial automation.
