CAN is low
cost
|
|
|
|
• |
Fast serial bus
with two wires: good price/performance ratio
|
|
|
|
• |
Low cost
protocol devices (controllers, transceivers) available mainly driven
|
|
|
by high volume
production in the automotive market

| q |
CAN is
reliable
|
|
|
|
• |
Sophisticated
error detection and error handling mechanisms results in high
|
|
reliability
transmission
|
|
|
|
• |
Example: 500
kbit/s, 25% bus load, 2000 hours per year:
|
|
|
One undetected
error every 1000 years
|
|
|
|
• |
Erroneous
messages are detected and repeated
|
|
|
|
• |
System-wide data
consistency (every bus node is informed about an error)
|
|
|
|
• |
Faulty nodes
automatically withdraw from bus communication
|
|
|
|
• |
High immunity to
Electromagnetic Interference
