Flow-based programming application for ctrlX OS CORE The Node-RED app is the Node-RED framework adapted for Bosch Rexroth’s ctrlX AUTOMATION. The open-source tool Node-RED is under the Apache 2.0 license and is a graphical development tool developed by IBM. On the server side, the framework is based on Node.js, while it is operated via a graphical user interface in the browser. With Node-RED, different nodes for input, output and processing can be connected to each other in a so-called flow. This allows data to be processed and various processes or devices to be monitored and controlled. The Node RED user interface, called the Flow Editor, consists of three main areas, the Node Panel, the Sheet Panel, and the Info and Debug Panel. The node panel on the left contains a list of the installed and available nodes. These are divided into categories, such as input and output categories, and can also be expanded via the package manager. The Sheet Panel in the middle defines the workspace with the so-called flows. The nodes from the Node Panel are added, connected and configured here by drag & drop. The Info and Debug Panel on the right side is divided into tabs. The information area displays the description of a selected node. The debug node outputs or internal errors are listed in the Debug Panel. The Node-RED Dashboard tab provides access to a live data dashboard that was created from the Node Panel of the Flow Editor via a series of nodes. The dashboard layout should be viewed as a grid in which different objects can be arranged according to the application needs.
