SHARE

Web-based Communication Life­cycle Manager, based on the ODX standard. With integrated code generator. Communication Lifecycle Manager 2.0 (CLCM 2.0): The CLCM 2.0 of Sontheim Industrie Elektronik GmbH is a central system for the management and creation of diagnostic and com­mu­ni­ca­tion de­scrip­tions of ECUs and entire vehicles. It is a client-server based web application that allows several users to work together on a project. No client installation is required and the server can be accessed from different platforms via the browser. The CLCM 2.0 can be integrated into the existing in­fra­struc­ture and de­vel­opment process. Thus it can optimally accompany all steps in the development of ECUs and vehicles.

All advantages at a glance:

  • High-level overall vehicle structure du­ring the re­quire­ment phase
  • More precise specification of the ECUs du­ring the im­ple­men­ta­tion phase
  • Vali­da­tion of the de­scribed dia­gnos­tic and com­mu­ni­cation interfaces and the mapped bus systems during the test phase
  • Provision of generated source code, documentation and diagnostic description after the release

Description of diagnostics and com­munication

The diagnostic interface of the ECUs is defined in ODX 2.2.0 format. In addition, a description of the communication between the ECUs within the vehicle network can be added. The described dia­gnos­tic data serve as a database for source code generation and doc­u­men­ta­tion. The data is stored on a database server, which enables the man­age­ment of large diagnostic projects. Existing legacy data or data provided by the supplier can be imported at any time. An in­te­gra­ted vers­io­ning history displays all chan­ges in the database and allows access to older data statuses for export or display.

The CLCM 2.0 is independent of the protocol and com­mu­ni­ca­tion system used to describe the diagnostic and com­mu­ni­ca­tion data. Thus various technologies are supported, including: CAN, K-Line, Ethernet, EtherCAT, J1939, KWP2000onCAN, UDS, CANOpen, UDP, TCP/IP etc.

Code Generator

The CLCM 2.0 has a customizable code generator that can be used to create source code and documentation based on the dia­gnos­tic data. The output is fully cus­to­miz­able and can be used by dif­fer­ent plat­forms and pro­gram­ming languages. This allows in­te­gra­tion into ex­is­ting software modules and libraries.

Possible areas of application are:

  • Source code for ECU software, dia­gnos­tic app­li­ca­tions and test environments
  • Documentation for the development, production and service departments
  • The code generator can be integrated into the customer-specific build infrastructure.

Extension API

The CLCM 2.0 has an extension API that allows you to change the default views and create new cus­tom views. Extensions are written in a .NET pro­gram­ming language (e.g. C#) and have access to the complete diagnostic data of the projects.
