Display of J1939 Signals in Graphics Window
Last updated: 2018-10-25
Question:
Why are not all values from certain J1939 signals displayed in graphics window?Answer:
J1939 signals defined with the attribute “SigType” of value “Discrete” in the database file (DBC) represent discrete values taken from a value table. Especially signals with 2 or 4 bits are treated distinctly in accordance to the J1939 standard. These values represent a certain meaning (0=not active, 1=active, 2=error, 3=not available).As it is for example not reasonable to display a signal not available, it is not displayed.
If you want to suppress this treatment in order to get all signal values displayed in graphics window, you have to edit the database and set the signal attribute “SigType” to the value “Default”.
Starting with CANoe/CANalyzer 7.1 you will have the option to disable this behaviour by unchecking the J1939 checkbox in the graphic window configuration panel.
