Fault buffer mechanism

PROFIdrive profile has a mechanism that can store eight fault
situations to PROFIdrive parameters. Fault and diagnostic data,
like fault number, fault code and fault time can be accessed
simultaneously with only one subindex. The mechanism consists
of six PROFIdrive parameters:
• PNU944: Fault message counter
• PNU945: PROFIdrive fault codes presented in the table above
• PNU946: Fault code list converts fault numbers to fault codes
• PNU947: Fault numbers according to DRIVECOM profile
• PNU948: Fault time
• PNU952: Fault situation counter
