SAE J2602-1 2005 LIN Network for Vehicle Applications(4)

LIN Network for Vehicle ApplicationsIssued 2004-08Revised 2005-09Superseding J2602-1 AUG2004

The LIN Specifications contain more than just a definition of the LIN protocol and physical layer. In addition, a Work Flow Process, Diagnostics and Configuration methods, definition of an Application Program Interface (API), file structures for a Node Capability File (NCF) and a LIN Description File (LDF) and semantics are identified as required (mandatory in all implementations). However, since there is a great deal of flexibility in the protocol and physical layer, applicability of these specifications to J2602 networks will be further specified in this document. 1.4

Relationship to the LIN Specifications (ref Section 2.6, LIN 2.0 Specification Package)

As described in the LIN Specification Package, the LIN 2.0 protocol specification suite consists of seven documents: 1.4.1

LIN SPECIFICATION PACKAGE

The LIN Specification Package provides an overview of the LIN Protocol, its features, and work flow. This includes the Revision History, LIN Overview and Glossary. 1.4.2

LIN PHYSICAL LAYER SPECIFICATION

The LIN Physical Layer Specification describes the physical layer, including bit rate, clock tolerances, etc. 1.4.3

LIN PROTOCOL SPECIFICATION

The LIN Protocol Specification describes the data link layer of LIN. 1.4.4

LIN DIAGNOSTIC AND CONFIGURATION SPECIFICATION

The LIN Diagnostic and Configuration Specification describes the services that can/may be layered on top of the data link layer to provide for diagnostic messages and node configuration. 1.4.5

LIN API SPECIFICATION

The LIN API Specification describes the interface between the network and the application program, including the diagnostic module. 1.4.6

LIN CONFIGURATION LANGUAGE SPECIFICATION

The LIN Configuration Language Specification describes the format of the LIN description file, which is used to configure the complete network and serve as a common interface between the OEM and the suppliers of the different network nodes, as well as an input to development and analysis tools. 1.4.7

LIN NODE CAPABILITY LANGUAGE SPECIFICATION

The LIN Node Capability Language Specification describes a format used to describe off-the-shelf slave nodes that can be used with a system definition tool to automatically create LIN Description Files. The remainder of this document (SAE J2602) will directly reference these LIN specifications.

3.1.2

DATA LINK LAYER

This provides for the reliable transfer of information across the physical layer. It includes the message structure, framing and error control. 3.1.3

DOMINANT SIGNAL

The driven and low voltage state of the LIN bus. If multiple devices access the bus, this state dominates the recessive or non-driven state. 3.1.4

“DORMANT” STATE

The state in which the slave task state machine is waiting for reception of the Break / Synch sequence. 3.1.5

MASTER NODE

Responsible for initiating all message traffic. See the Glossary of the LIN Specification Package for additional information. 3.1.6

MEDIA

The physical entity that conveys the electrical (or equivalent means of communication) signal transmission among ECUs on the network. 3.1.7

PHYSICAL LAYER

This ISO 7498 subsection consists of the media, mechanical interconnections, and transceivers that provide the interconnection between all ECU nodes. 3.1.8

PROTOCOL

The formal set of conventions or rules for the exchange of information among the ECUs. This includes the specification of the signal frame administration, frame transfer and physical layer. 3.1.9
