CAN Communication 27/30 Question 1 How many parts does ISO 11898 consist of? 1 2 3 4 Question 2 The CAN protocol covers the following layers of the ISO/OSI reference model: Layers 1 and 2 Layers 3 and 4 Layers 5 and 6 Layer 7 Question 3 Which component of a CAN node handles the CAN protocol? Microcontroller CAN Controller CAN Transceiver Question 4 A CAN controller without object storage is characterized by the following properties: Automatic response to remote frames High costs Alternating receive buffer User-configurable buffer Question 5 A low-speed CAN transceiver is characterized by the following properties: Data rates up to 1 Mbit/s Error tolerance Generation of an unsymmetrical signal Question 6 Reflections in high-speed CAN networks are avoided by termination of the bus ends. YES

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 Layer : 1 Mbit/s Low-speed CAN Layer : 125 kbit/s

Question 8 A logical “0” corresponds to the recessive bus level in a CAN network. NO Question 9 A CAN network has the following underlying architecture: Master-slave system and line topology Master-slave system and ring topology Multi-master system and line topology Multi-master system and ring topology Question 10 In a CAN network, all CAN nodes are independent of one another. YES
