BS ISO 17987-2:2016规定了为满足以下要求而定制的传输协议和网络层服务: 基于LIN的车辆网络系统对本地互联网络的要求。协议 指定未确认的通信。LIN协议支持ISO 14229-2中规定的标准化服务原语接口。本文档提供了传输协议和网络层服务，以支持不同的 应用层实现类似于正常通信消息和诊断通信消息。传输层定义了包含在一个或多个帧中的数据的传输。这个 传输层消息由诊断帧传输。标准化的API是为 传输层。传输层的使用针对的是在主干总线上执行诊断的系统 （例如CAN）以及系统构建器希望在LIN子总线上使用相同诊断功能的位置 集群。 这些信息实际上与ISO 15765-2和承载这些信息的PDU相同 它们非常相似。传输层的目标是在LIN主节点上实现低负载，直接在LIN从节点上提供完整（或其子集）诊断，并针对使用强大LIN节点构建的集群（而不是主流的低成本集群）。典型的系统配置如图1所示。交叉引用:ISO 14229-1ISO 14229-2ISO 14229-7:2015ISO 17987-3:2016ISO 17987-4ISO/TR 17987-5ISO 17987-6ISO 17987-7ISO/IEC 7498-1ISO/IEC 10731购买本文件时提供的所有现行修订均包含在购买本文件中。

BS ISO 17987-2:2016 specifies a transport protocol and network layer services tailored to meet the requirements of LIN-based vehicle network systems on local interconnect networks. The protocol specifies an unconfirmed communication.The LIN protocol supports the standardized service primitive interface as specified in ISO 14229-2.This document provides the transport protocol and network layer services to support different application layer implementations likenormal communication messages, anddiagnostic communication messages.The transport layer defines transportation of data that is contained in one or more frames. The transport layer messages are transported by diagnostic frames. A standardized API is specified for the transport layer.Use of the transport layer is targeting systems where diagnostics are performed on the backbone bus (e.g. CAN) and where the system builder wants to use the same diagnostic capabilities on the LIN subbus clusters. The messages are in fact identical to the ISO 15765-2 and the PDUs carrying the messages are very similar.The goals of the transport layer arelow load on LIN master node,to provide full (or a subset thereof) diagnostics directly on the LIN slave nodes, andtargeting clusters built with powerful LIN nodes (not the mainstream low cost).A typical system configuration is shown in Figure 1.Cross References:ISO 14229-1ISO 14229-2ISO 14229-7:2015ISO 17987-3:2016ISO 17987-4ISO/TR 17987-5ISO 17987-6ISO 17987-7ISO/IEC 7498-1ISO/IEC 10731All current amendments available at time of purchase are included with the purchase of this document.
