Need a simple intro to CANopen? In this video tutorial we introduce the CANopen protocol incl. the object dictionary, services, SDO, PDO and master/slave nodes. CANopen is a CAN based communication protocol - used in particular within industrial automation (e.g. robotics), medical equipment and automotive. The protocol enables off-the-shelf integration of CANopen nodes - and easy configuration after installation. The CANopen protocol has six core concepts: Communication models (master/slave, producer/consumer, client/server), communication protocols (e.g. PDO and SDO services), device states, the Object Dictionary (OD), Electronic Data Sheet (EDS) and device profiles (standardized by CAN in Automation, CiA). In this intro we also briefly introduce CANopen data logger use cases, including logging CANopen node data, warehouse fleet management, predictive maintenance and blackbox diagnostics.
