16.3.3 Fault Buffer Mechanism
The PROFIdrive profile provides a fault buffer that can store eight fault situations to PRO-
FIdrive parameters. A fault situation, which may be associated with one or several fault
messages, generates a device-specific fault reaction.
The fault buffer contains the fault messages which have been generated during the fault
situation; the fault number list contains explanations and assignments to the various fault
messages defined in the device.
The fault messages are entered into the fault buffer in the sequence in which they are
detected. This means that each line in the fault buffer represents a fault message; the
fault number of a fault message may be addressed in the particular parameter using the
same subindex.
The error must be acknowledged after eliminating the cause. After resetting an error, this
error is moved from the actual situation memory (PNU 947 sub indices 0-7) to the “fault
situation n-1”. This allows subsequent tracking of the faults. The PNU 944 (fault message
counter) increments each time the fault buffer changes.
The PROFINET Fault Buffer (PNU 947) is volatile.
