Описание (английский):

This document specifies the LIN protocol including the signal management, frame transfer, schedule table handling, task behaviour, status management, and commander and responder node. It contains also OSI layer 5 properties according to ISO 14229-7 UDSonLIN-based node configuration and identification services (SID: B016 to B816) belonging to the core protocol specification. A node (normally a commander node) that is connected to more than one LIN network is handled by higher layers (i.e. the application) not within the scope of this document.

Overview

ISO 17987-3:2025 - "Road vehicles - Local Interconnect Network (LIN) - Part 3: Protocol specification" defines the logical protocol requirements for LIN, the low-cost UART-based in-vehicle network used for low-speed control functions. The standard specifies signal management, frame transfer, schedule table handling, task behaviour, status management and the roles of commander and responder nodes. It also includes OSI layer 5 properties for UDS-on-LIN node configuration and identification services (per ISO 14229-7). Hardware-specific details are addressed in other parts of the ISO 17987 series.

Key topics and requirements

Signal management: definition, types, packing, consistency, and transmission/reception rules for LIN signals.

Frame transfer and structure: frame types, identifiers, transfer mechanics and frame length constraints.

Schedule tables: deterministic, time-defined frame scheduling and slot handling for predictable communication.

Task behaviour models: commander and responder state machines and task-level interactions.

Status management: error detection, reporting, event-triggered frames and cluster reporting.

Node configuration and identification: LIN product IDs (supplier, function, variant), serial numbers, memory model, responder configuration variants, PDU structure and services for node configuration.

Transport and diagnostics: transport-layer support for larger PDUs and handling of diagnostic services (UDSonLIN).

Auto-addressing: normative procedures for automatic node addressing (Annexes C–F).

Standards alignment: OSI model mapping (ISO/IEC 7498-1) and interaction with ISO 14229-7 for UDS services.

Inclusive terminology: replaces “master/slave” with commander/responder; updated from the 2016 edition.

Applications and users

ISO 17987-3:2025 is targeted at automotive and embedded-systems professionals implementing LIN-based communication for low-cost control modules such as:

Door modules, window lifts and central locking

HVAC and climate control units

Seat control and mirror adjustment systems

Body electronics and simple actuator/sensor clusters

Primary users:

ECU firmware engineers and system architects

Automotive communication-stack and tool vendors (LIN stack, diagnostics, node configuration tools)

Test engineers and integrators validating schedule tables, frame timing and diagnostics

OEMs and tier-1 suppliers specifying network behaviour and node conformance
