354 PROFINET IO – Communication protocol
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 Fault
code mapping on page 352.
• 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.
