￭ Fault buffer mechanism
The PROFIdrive profile has a mechanism that can store eight fault situations to PROFIdrive
parameters. Fault and diagnostic data, like fault number and fault code, can be accessed
simultaneously with only one subindex. The mechanism consists of four PROFIdrive
parameters:
• PNU944: Fault message counter.
• Incremented each time the fault buffer changes.
• PNU945: PROFIdrive fault codes presented in section on page .
• PNU946: Fault code list that converts fault numbers to fault codes.
• Read using the fault number as a subindex to get the corresponding fault code.
• PNU947: Fault numbers according to the DRIVECOM profile.
The table below illustrates the structure of a fault buffer. The fault buffer consists of two
parameters: fault number (PNU 947) and fault code (PNU 945). The rows of the fault buffer
are represented by the parameter subindices. Fault messages are entered into the buffer
in the sequence they are detected. Each line in the fault buffer represents a fault message,
which is a part of a fault situation. A fault situation lasts from a detection of a fault to its
acknowledgement.
