Node-RED is a visual tool for wiring the Internet of Things, by wiring together hardware devices, APIs and online services in new and interesting ways. It is an open-source, cross-platform technology. Node-RED nodes for the company’s industrial programmable automation controllers (PACs), significantly decrease IIoT application development time and complexity, making it easier to prototype and develop applications for connecting physical assets to cloud applications. The development environment offers a gradual and easily approachable learning curve for users of all levels and requires little to no programming skills. Instead, it takes advantage of pre-programmed, reusable code blocks called nodes. These nodes make IIoT application development simpler, easier to repeat, and faster to scale. Through a visual browser-based, drag-and-drop interface, Node-RED allows IIoT application developers to focus on identifying an opportunity and developing a solution, rather than building the components of an application from scratch. Nodes and a RESTful API for the company’s SNAP PAC R-series and S-series controllers are available free for download.
