Search tips

apple banana
Find rows that contain at least one of the two words.

+apple +juice
Find rows that contain both words.

+apple macintosh
Find rows that contain the word 'apple', but rank rows higher if they also contain 'macintosh'.

+apple -macintosh
Find rows that contain the word 'apple' but not 'macintosh'.

+apple ~macintosh
Find rows that contain the word 'apple', but if the row also contains the word 'macintosh', rate it lower than if row does not. This is "softer" than a search for '+apple -macintosh', for which the presence of 'macintosh' causes the row not to be returned at all.

+apple +(>turnover >strudel)
Find rows that contain the words 'apple' and 'turnover', or 'apple' and 'strudel' (in any order), but rank 'apple turnover' higher than 'apple strudel'.

Find rows that contain words such as 'apple', 'apples', 'applesauce', or 'applet'.

"some words"
Find rows that contain the exact phrase 'some words' (for example, rows that contain 'some words of wisdom' but not "some noise words").

Diagnostic with SAE J1939 - Usage of CDD and DBC

Last updated: 2019-11-29

The SAE J1939 recommended practice contains several Diagnostic specific frames with DMx as acronym.

Some of these frames are used for diagnostic purposes „on-board“, during the drive. They build for instance the input for the central display, informing the driver on actual defects. Most of these DM-frames are broadcasted (BAM). They are defined in the J1939 dbc.

As Off-Board diagnostic is concerned, and for the communication with an external workshop terminal, especially in Europe KWP2000 or UDS is used. Both Diagnostic protocols require ISO TP 15765 as transport protocol. To avoid collision with J1939, special care has been taken within ISO TP 15765-2 (Annex A) concerning the TP-specific 29 bits long frames definition.

In particular the value 0 is given to both Extended Data Page (EDP=0) and Data Page (DP=0) bit fields in the 29 bits Identifier.

As a consequence, only 4 TP-specific identifiers are possible for Diagnostics purposes, if J1939 is used. These identifiers shall be defined in the CDD of CANoe's Diagnostics configuration:

For normal fixed addressing:

  • 0x18DA + DA + SA, for physical addressing
  • 0x18DB + DA + SA, for functional addressing

For mixed addressing:

  • 0x18CE + DA + SA for physical addressing
  • 0x18CD + DA + SA for functional addressing


If you have a CDDT file with an extended CAN address interface it is possible to copy this interface to the other CDDT with a CANdelaStudio Admin Edition. If you need a sample CDDT, please contact Vector Support.
