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
