File Structures for a Node Capability File (NCF) and LIN Description File (LDF)
J2602-3_202110
This document covers the requirements for SAE implementations based on ISO 17987. Requirements stated in this document will provide a minimum standard level of performance to which all compatible systems, design and development tools, software, ECUs, and media shall be designed. This will assure consistent and unambiguous serial data communication among all connected devices regardless of supplier.
This document may be referenced by any vehicle OEM component technical specification that describes any given ECU in which the single wire data link controller and physical layer interface is located.
The intended audience includes, but is not limited to, ECU suppliers, LIN controller suppliers, LIN transceiver suppliers, component release engineers, and vehicle system engineers.
The term “master” has been replaced by “commander” and term “slave” with “responder” in the following sections.
Rationale:
The scope of this document covers the outcome of an analysis, performed by the SAE J2602-3 Task Force, of the application program interface, node configuration file, and LIN description file portions of the ISO 17987 specifications. The purpose of the analysis was to identify and resolve requirements in these specific specifications that are ambiguous, conflicting, or optional, and to document a method for accommodating SAE J2602 node and network specific data elements in the ISO 17987 NCF/LDF file structure(s). Development and adoption of this recommended practice will allow the design and development tools to consistently identify, extract, interpret, and utilize the required information relative to specific network operational characteristics. This document was updated to match SAE J2602-1 (2021 revision).
