Diagnostic Signals in the INCA Variable Selection

The diagnostic data that can be read about the ODX project at the diagnostic interface of an ECU can also be measured and recorded in a measure file with INCA and ODX-LINK. The prerequisite for this is the definition of diagnostic signals in the ODX project.

The diagnostic signals of the ODX project are described in the diagnostic signal list (DSL) – the signals defined there can be used in the same way as standard measure variables in INCA's "Variable Selection" window.

If users want to work with their own ODX data, it is possible to generate such signals in the INCA experiment and add them to the ODX project. This function is available for the user views "Diagnostic Services" and "Service Inspector" (see Adding Diagnostic Signals).

When you install ODX-LINK, the ODX projects "OBDonCAN_ETAS_SAEJ1979<Version>.pdx" and "OBDonUDS_ETAS_SAEJ1979<Version>.pdx" already contains one DSL file. When using this ODX project, the "Variable Selection" window in INCA features an additional diagnostic device with the diagnostic signals of the OBDSignalList.dsl file contained.

The diagnostic device is named in accordance with the following conventions:

<Device name>#<Logical Link>#Diagnostics
