Introduction
The Diagnostic Extract is a standardized AUTOSAR exchange format on diagnostic functionality (DCM, DEM and FIM), formalized as an ARXML file.
During an ECU development project, three main roles (OEM, Application Developer and ECU Integrator) exchange Diagnostic Extract files.
Therefore, the Diagnostic Extract format is based on the Diagnostic Extract Template (DEXT) that allows gradual enrichment of definitions by the different roles.
Further, it supports the automatic code generation process for diagnostic modules.
Scope
In this guide we will explain how to create a Diagnostic Extract file with a UDS configuration through the DEXT Editor of ISOLAR-AB.
Definitions and Abbreviations
BSW: AUTOSAR Basic Software, Hardware independent service layer
DCM: Diagnostic Communication Manager
DDDI: Dynamically Define Data Identifier
DEM: Diagnostic Event Manager
DEXT: Diagnostic Extract Template
DID: Diagnostic Identifier
DTC: Diagnostic Trouble Codes
FIM: Function Inhibition Manager
IOC: Input Output Control
OS: AUTOSAR Operating System
RTE: AUTOSAR Run-Time Environment
RDBI: Read Data By Identifier
UDS: Unified Diagnostic Services
WDBI: Write Data By Identifier
Toolchain
It is assumed you are using the RTA-CAR 9.2.0 toolchain:
RTA-CAR 9.2.0 toolchain
ISOLAR-AB v 9.2.0
RTA-RTE v 7.5.0
RTA-BSW v 6.1.2
RTA-OS v 6.2.0
However, the workflow should be applicable also with previous versions of the toolchain.
