Can protocol interview questions?

CAN protocol explanation?

The Controller area network or CAN protocol is a method of communication between electronic devices embedded in a vehicle, such as the engine-management systems, active suspension, central locking, air conditioning, airbags, etc.

CAN TP interview questions?

What is the basic principle of CAN protocol?

The CAN communication protocol is a carrier-sense multiple-access protocol with collision detection and arbitration on message priority (CSMA/CD+AMP). CSMA means that each node on a bus must wait for a prescribed period of inactivity before attempting to send a message.

CAN protocol speed?

The maximum speed of a CAN bus, according to the standard, is 1 Mbit/second. Some CAN controllers will nevertheless handle higher speeds than 1Mbit/s and may be considered for special applications. Low-speed CAN (ISO 11898-3, see above) can go up to 125 kbit/s.

CAN protocol examples?

By the mid-1990s, CAN was the basis of many industrial device networking protocols, including DeviceNet and CANOpen. Examples of CAN devices include engine controller (ECU), transmission, ABS, lights, power windows, power steering, instrument panel, and so on.

What is CANOpen protocol?

CANopen is a high-level communication protocol and device profile specification that is based on the CAN (Controller Area Network)protocol. The protocol was developed for embedded networking applications, such as in-vehicle networks. … The data link layer includes the fact that CAN is a frame-based (messages) protocol.

Why we use CAN protocol?

Why CAN is having 120 ohms at each end Mcq?

Why Can Is Having 120 Ohms At Each End? Answer : To minimize the reflection reference, to reduce noise. To ensure that reflection does not cause communication failure, the transmission line must be terminated.

Why is CAN message oriented protocol?

Q10: Why CAN is the message-oriented protocol? … This means that messages are not transmitted from one node to another node based on addresses. Embedded in the CAN message itself are the priority and the contents of the data being transmitted.

What is protocol in simple words?

1 : a system of rules that explain the correct conduct and procedures to be followed in formal situations The soldier’s actions constitute a breach of military protocol. They did not follow the proper diplomatic protocols.

CAN transceiver converts?

The role of the transceiver is simply to drive and detect data to and from the bus. It converts the single-ended logic used by the controller to the differential signal transmitted over the bus. … The transceiver distinguishes between two bus logic states, dominant and recessive.

CAN protocol frame?

CAN protocol maximum speed?

The maximum speed of a CAN bus, according to the standard, is 1 Mbit/second. Some CAN controllers will nevertheless handle higher speeds than 1Mbit/s and may be considered for special applications. Low-speed CAN (ISO 11898-3, see above) can go up to 125 kbit/s.

CAN protocol disadvantages?

What is low-speed and high speed?

Typically, a distinction is made between high-speed CAN transceivers and low-speed CAN transceivers. High-speed CAN transceivers support data rates up to 1 Mbit/s. Low-speed CAN transceivers only support data rates up to 125 kbit/s.
