What is LIN protocol?
LIN (Local Interconnect Network) is a serial network protocol used for communication between components in vehicles. It is a Single wire-serial network protocol that supports communications up to 19.2 Kbit/s at a bus length of 40 meters.
How does LIN communication work?
How does LIN bus work? LIN communication at its core is relatively simple: A master node loops through each of the slave nodes, sending a request for information – and each slave responds with data when polled. The data bytes contain LIN bus signals (in raw form).
What criteria determine the choice of using LIN as a communication bus?
What criteria determine the choice of using LIN as a communication BUS?
What are the types of LIN communication protocol frames?
There are three different ways of transmitting frames on the bus: unconditional, event triggered, and sporadic frames.
- Unconditional Frames. This is the “normal” type of LIN communication.
- Event Triggered Frames.
- Sporadic Frames.
Where is LIN protocol used?
Modern automotive networks use a combination of LIN for low-cost applications primarily in body electronics, CAN for mainstream powertrain and body communications, and the emerging FlexRay bus for high-speed synchronized data communications in advanced systems such as active suspension.
What voltage is LIN bus?
The LIN bus, and LIN transceivers, typically operate at voltages ranging from 9 V to 18 V, but some go up to 30 V, depending on the application; a typical vehicle is a 12-V battery system, but some larger vehicles go up to 24 V.
CAN LIN protocols?
LIN operates under a CAN… The Local Interconnect Network (LIN) protocol specification provides a low-cost, short-distance, and low-speed network, enabling the implementation of a new level of electronics intelligence in automotive subsystems.
How do you test LIN communication?
An easy way to check the LIN wiring is to unplug the slave module and check the ‘at rest’ voltage of the LIN wire. The master should send out the 7 to 12 volt reference. If the wiring to the multi-function switch checks out good, replace the switch. If the input shows to be correct, check the bussed outputs.
What is PID in LIN?
The Protected Identifier Field (PID) consists of two sub-fields; the frame identifier and the parity. Bits 0 to 5 are the frame identifier and bits 6 and 7 are the parity.
What is automotive LIN bus?
The Local Interconnect Network (LIN) bus was developed to create a standard for low-cost, low-end multiplexed communication in automotive networks. LIN provides cost-efficient communication in applications where the bandwidth and versatility of CAN are not required.
What is NAD in LIN?
Configured node address (NAD) of a LIN slave node. NAD is the address of a slave node and is used in diagnostic services. Initial NAD is replaced by Configured NAD with node configuration services. This property must be defined before reading, either by writing to the property or by importing from an LDF.
CAN and LIN protocol difference?
The CAN bus allows for components to talk to each other seamlessly in the automobile. The LIN bus allows for further expansion to peripheral devices. This bus hierarchy was designed to save costs and wiring.
