The first fully implemented version of the new LIN specification was published in November 2002 as LIN version 1.3. In the late 1990s the Local Interconnect Network (LIN) Consortium was founded by five European automakers, Mentor Graphics (Formerly Volcano Automotive Group) and Freescale (Formerly Motorola, now NXP). It is intended to complement the existing CAN network leading to hierarchical networks within cars. It is particularly intended for mechatronic nodes in distributed automotive applications, but is equally suited to industrial applications. The LIN bus is an inexpensive serial communications protocol, which effectively supports remote application within a car's network. These sub-systems can be connected by back-bone-network (i.e. The master and slaves are typically microcontrollers, but may be implemented in specialized hardware or ASICs in order to save cost, space, or power.Ĭurrent uses combine the low-cost efficiency of LIN and simple sensors to create small networks. Because all communications are initiated by the master it is not necessary to implement a collision detection. The master node can also act as a slave by replying to its own messages.

Īll messages are initiated by the master with at most one slave replying to a given message identifier.

LIN is a broadcast serial network comprising 16 nodes (one master and typically up to 15 slaves). 6 Slave node position detection (SNPD) or autoaddressing.ĬAN in Automation has been appointed by the ISO Technical Management Board (TMB) as the Registration Authority for the LIN Supplier ID standardized in the ISO 17987 series. LIN over DC power line (DC-LIN) was standardized as ISO/AWI 17987-8. LIN may be used also over the vehicle's battery power-line with a special LIN over DC power line (DC-LIN) transceiver. In September 2003, version 2.0 was introduced to expand capabilities and make provisions for additional diagnostics features. The first fully implemented version of the new LIN specification (LIN version 1.3) was published in November 2002. In the late 1990s, the LIN Consortium was founded by five automakers ( BMW, Volkswagen Group, Audi, Volvo Cars, Mercedes-Benz), with the technologies supplied (networking and hardware expertise) from Volcano Automotive Group and Motorola. European car manufacturers started using different serial communication technologies, which led to compatibility problems.

The need for a cheap serial network arose as the technologies and the facilities implemented in the car grew, while the CAN bus was too expensive to implement for every component in the car. It is a single wire, serial network protocol that supports communications up to 19.2 Kbit/s at a bus length of 40 meters. LIN ( Local Interconnect Network) is a serial network protocol used for communication between components in vehicles.
