Figure 13.
illustrates the structure of a fault buffer. The fault buffer
is composed of four parameters, fault number (PNU 947), fault
code (PNU 945), fault time (PNU 948) and fault value (PNU 949).
The rows of the fault buffer are represented by the parameter sub-
indices. 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.
Fault situation lasts from a detection of a fault to its
acknowledgement. Faults that are detected during an active fault
are included to the fault situation.
