The udiExceptionNumber of a ST_Exception structure has to be a unique number to identify the exception which is used on e.g. a HMI to translate the exception into local language. The structure of udiExceptionNumber is defined as XXXYYYY where YYYY is the value of ET_DiagExt which describes the exception, and XXX is the value of ET_ExceptionSource which specifies the ET_DiagExt table where the ET_DiagExt comes from.
The input i_udiDiagExt is devided modulo by 10000. If values are given to the input greater than 9999, the result is not a unique number anymore, because there can be another ET_DiagExt with a value below 10000 which leads to the same number.

q_etDiag |
General, library-independent statement on the diagnostic. A value unequal to GD.ET_Diag.Ok corresponds to a diagnostic message. |
