ABSTRACT
The local interconnect network (LIN) is an open communication standard, enabling fast and cost-efficient implementation of low-cost multiplex systems. It supports encapsulation for model-based design and validation, leading to front-loaded development processes which are faster, and more cost efficient than traditional development methods. LIN promotes scaleable architectures and interoperability of network nodes from the viewpoint of hardware and software, and a predictable electromagnetic compliance behavior. LIN messages are scheduled in a time-triggered fashion. This provides a model for the accurate calculation of latency times—thus supporting fully predictable behavior. The entities that are transferred on the LIN bus are frames. One message frame is formed by the header and the response part. The LIN description file (LDF) can be one component used to generate software for an electronic control units which shall be part of the LIN network. The LDF is typically also used for verification, rest-bus simulation and as a configuration item.
