CANbus Training


Course duration: 1 day


CANopen is a high-level communication protocol and device profile specification that is based on the Controller Area Network (CAN) protocol. CANopen is extensively used in motor control, and its core operation is within industrial automation networks by enabling standardised plug and play installations for new devices connected within the network.

Course Outline


The course begins with an introduction to CANopen and its history. We see where CANopen fits in as a digital communications system and what its advantages are over traditional analogue systems.

We look at the different layers of the CANopen protocol and advise on the best installation and implementation requirements of the bus:

  • Basic knowledge
  • Application layer (CANopen basic concepts, network administration, PDO, SDO, SFO)
  • Link layer (CAN frame formats, exchange protection)
  • Physical layer (Network characteristics, recommended connections)
  • Diagnostics (LEDs, diagnostic PLC objects, tools)
  • Useful CAN components (Interfaces, repeaters, bridges, medium converters)


The course is then followed by a tutorial and practical session:

  • Setting up CANopen communication instances
  • Sniffing CAN data on the bus with the use of a bus analyser
  • Running diagnostics on a CANopen network under various scenarios





We limit training groups to a maximum of 8 people. Training will only take place if more than 4 people have booked.



The Johannesburg based course will be run from the IDX offices in Fourways.
