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 provides a browser-based flow editor. This provides an easy way to visually see and modifies your program flow. Flows can then be deployed to the runtime in a single click. Node-RED is built on Node.js. This lightweight runtime can be deployed on low-cost hardware (Raspberry Pi ) or cloud services (Microsoft Azure). This has the ability to bring data collection, analysis, and storage closer to the actual device. Real-time edge computing can then be achieved without latency issues.
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.
