Node-RED is a visual programming tool for connecting physical hardware devices, APIs, and online services together as part of the Internet of Things. Node-RED’s low-code, drag-and-drop interface makes it easy to create complex flows with minimal code.

The CLICK PLUS family of controllers now has an Intelligent option slot module that combines time-tested CLICK hardware with the popular Node-RED open-source tool already installed. Node-RED has a large library of built-in nodes for various tasks, including input/output, data processing, logic, and social media functions.

The C2-NRED module has its own processor ensuring the main CPU remains unburdened but has direct access to the memory of the PLC and all the data exchanges needed to easily create a working application. The user can even determine which controller (PLC or C2-NRED or both) will control the process and several Node-RED nodes are available for working specifically with the CLICK PLUS PLC.
