ctrlX Apps – Node-RED CAN bus message processing

More frequently, manufacturing equipment interfaces with CAN bus to battery systems. Be it for battery testing, charging, discharging or use as energy buffer, e.g., using ctrlX DRIVE. The ctrlX App Node-RED can be used to - setup the communication, - read and write CAN bus messages, - create a Battery Node-RED dashboard, and - share data via the innovative ctrlX data layer with other Apps running in the ctrlX CORE. In this example, the CAN bus from the BMS (Battery Management System) of the Lithionics Battery® is connected to the USB-C port at the ctrlX CORE X3 using a “CANBUS to USB” adapter. • Video topics 00:08 Introduction 01:16 Adapter CAN bus to USB 03:05 ctrlX Works engineering software to connect with ctrlX CORE 03:24 Node-Red App in ctrlX CORE - Setup communication - Open and close communication - automatic control of communication channel - CAN bus communication status in dashboard 12:49 Decoding CAN bus messages proadcasted by the BMS (Battery Management System) - product ID of the BMS - battery voltage and current - decoding battery status information 21:02 Writing to the BMS - switch BMS DC contactors Off - switch BMS DC contactors On 23:32 Finalize the Web-based Node-RED dashboard for Lithionics Battery Product documentation, go to https://www.boschrexroth.com/en/us/search.html?q=ctrlx+en&num=10&origin=header and search for “ctrlX en” Visit ctrlX AUTOMATION at https://developer.community.boschrexroth.com/t5/ctrlX-AUTOMATION-Community/ct-p/dcdev_community The online site to - become a member of the ctrlX AUTOMATION COMMUNITY - explore the many Apps in the ctrlX STORE - quickly find under How-To information (FAQs, Examples, Technotes and How-To) - use the ctrlX Forum to post, interact and find solutions - access the product documentation download area - go to the ctrlX AUTOMATION in GitHub Full playlist at: https://www.youtube.com/playlist?list=PLYFUPeujnKJVpft2-dvQzf9ZDTUA-exk- Follow @boschrexroth Bosch Rexroth Facebook: https://www.facebook.com/BoschRexrothUS Bosch Rexroth X: https://x.com/BoschRexrothUS Bosch Rexroth LinkedIn: https://www.linkedin.com/company/boschrexroth
