Local Interconnect Network - the LIN Bus System

The cost-effective alternative to CAN in the automotive test

The LIN bus (Local Interconnect Network) was developed at the end of the nineties as a standard for simple and cost-effective communication in automotive networks and has since achieved a very rapid spread in automotive electronics. The starting point for its introduction was the foreseeable need to reduce the communication volume of the CAN networks, which had reached the limits of their capacity due to the large number of control units and high data volumes in the vehicle. From an economic point of view, the aim was to provide a cheaper, feasible alternative to the more costly CAN interface.

The bus system offers efficient communication in applications that do not depend on the versatility and bandwidth of CAN and sees itself as its "downward" complement. Typical applications of the bus are control units for seat adjustment, window lifters, air-conditioning systems or other simple sensor-actuator applications. The transmission line is a bidirectional one-wire line (maximum data rate 20 kBit/s). LIN is based on widely used and therefore cost-effective standard UART interfaces. A LIN network always connects a limited number of control units with sensors and actuators in the vehicle, which form a self-contained functional unit. The coupling of individual LIN subsystems to the central CAN network of the vehicle is done in each case via a control unit with gateway function, the LIN master (has a master task as well as, in some cases, a slave task). The other participants on the LIN bus operate in slave mode (slave task).
