internal diagnostic code
4−36
This additional information is designed mainly for diagnostics
performed by FCT. It supplements the error number by
helpful information such as the record number. With active
messages, it also indicates whether the error can be
acknowledged and whether the cause is still active. The
coding is the same for the parameters:
PNU 203: Additional information with errors/warnings in
the diagnostic memory. Index 1 ... 100 corresponding to
the entry number.
PNU 227: Coding of the current status of a fault.
Index 1 ... 87 corresponding to the fault number.
Since several faults may be pending simultaneously, the in
formation of the PNU 227 needs to be available for every
error number separately. Therefore, when querying, the error
number must be specified as the index.
A S Reset Level
The coding is the same for PNU 203 and 227, but it only con
tains the information that is useful and available for the re
spective parameter.
