Introduction to CAN

     
CAN Communication
27/30


The learning objectives test contains questions for each learning unit of the chapter “CAN Communication”. At the end of the learning objectives test, you can have your answers checked. It is not necessary to answer all test questions. You can have the correct answer shown by clicking the key icon. The next time you call the learning objectives test, you can have your answers checked again.

If you experience difficulties answering the questions of the learning objectives test, simply review the relevant learning unit or practice with the interactive figure “CAN Network”. This interactive figure lets you call up key information on an individual component of a CAN network by clicking it with the mouse.
 

Question 1
How many parts does ISO 11898 consist of?
Question 2
The CAN protocol covers the following layers of the ISO/OSI reference model:
Question 3
Which component of a CAN node handles the CAN protocol?
Question 4
A CAN controller without object storage is characterized by the following properties:
Question 5
A low-speed CAN transceiver is characterized by the following properties:
Question 6
Reflections in high-speed CAN networks are avoided by termination of the bus ends.

Question 7
The CAN specification describes two physical layers: high-speed CAN physical layer and low-speed CAN physical layer. What is the range of data rates covered by the high-speed CAN physical layer per ISO-Standard 11898-2? What is the range of data rates covered by the low-speed CAN physical layer per ISO Standard 11898-3?
High-speed CAN Llayer
Low-speed CAN Layer
Question 8
A logical “0” corresponds to the recessive bus level in a CAN network.

Question 9
A CAN network has the following underlying architecture:
Question 10
In a CAN network, all CAN nodes are independent of one another.
