Product Code:SAE J2178/1
Title:Class B Data Communication Network Messages聴Detailed Header Formats and Physical Address Assignments
Issuing Committee:Vehicle Architecture For Data Communications Standards
Scope:This SAE Recommended Practice defines the information contained in the header and data fields of non-diagnostic messages for automotive serial communications based on SAE J1850 Class B networks. This document describes and specifies the header fields, data fields, field sizes, scaling, representations, and data positions used within messages.The general structure of a SAE J1850 message frame without in-frame response is shown in Figure 1. The structure of a SAE J1850 message with in-frame response is shown in Figure 2. Figures 1 and 2 also show the scope of frame fields defined by this document for non-diagnostic messages. Refer to SAE J1979 for specifications of emissions related diagnostic message header and data fields. Refer to SAE J2190 for the definition of other diagnostic data fields. The description of the network interface hardware, basic protocol definition, the electrical specifications, and the CRC byte are given in SAE J1850.SAE J1850 defines two and only two formats of message headers. They are the Single Byte header format and the Consolidated header format. The Consolidated header format has two forms, a Single Byte form and a three byte form. This document covers all of these formats and forms to identify the contents of messages which could be sent on a SAE J1850 network.This document consists of four parts, each published separately.SAE J2178-1 (Titles: Detailed Header Formats and Physical Address Assignments) describes the two allowed forms of message header formats, Single Bytes and Consolidated. It also contains the physical node address range assignments for the typical sub-systems of an automobile.SAE J2178-2 (Titled: Data Parameter Definitions) defines the standard parametric data which may be exchanged on SAE J1850 (Class B) networks. The parameter scaling, ranges, and transfer functions are specified. Messages which refer to these parametric defintions shall always adhere to these parametric definitions. It is intended that at least one of the definitions for each paramenter in this part matches the SAE J1979 definition.SAE J2178-3 (Titled: Frame IDs for Single Byte Forms of Headers) defines the message assignments for the single byte format and the one byte form of the consolidated header format.SAE J2178-4 (Titled: Message Definition for Three-Byte Headers) defines the message assignments for the three byte form of the consolidated header format.【英文标准名称】:Aerospace;rivetdesignvalues,staticload,foruniversalheadrivetjoints,singleshear;rivetmaterial3.3354
