Not implemented yet.
6.14 Fault
All actual faults can be described as a so called “Fault situation”. This fault situation can be
read from the fault buffer with PNU 947. A fault situation can have up to 8 different faults. An
unacknowledged is indicated by ZSW1 bit 3 (fault present). With acknowledging the actual
fault situation, the fault numbers are shifted to the acknowledged faults section (shift of 8 pos-
itions in the fault buffer (PNU 947)). Each time a fault situation is generated, a fault message
counter is incremented (PNU 944). With reading the value of the fault message counter
before and after the read process of the Fault buffer (947), the user can be sure that no other
fault situation has been occurred in the meanwhile if these values are equal.
The fault buffer PNU 947 store up to 8 fault situation. Each fault situation can have up to 8
fault numbers.
