PROFINET IO – Communication protocol 355
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.
