Description
10.46 Fault memory
r947
Fault memory
Display of fault messages generated in response to recent faults. A fault
(G189)
value and fault time is assigned to each fault number (see Section 10 for
details of fault numbers and fault values).The interrelationship between the
associated parameters is shown in the diagram below.
The fault numbers of the last (maximum 8) fault events are stored under the
indices of parameter P947. r947.001 displays the fault number of the current
(still not acknowledged) fault, index 9 displays the number of the most
recent acknowledged fault, index 17 the fault number of the second most
recent acknowledged fault, etc. An entry of "0" means that no "earlier" fault
has occurred. Since only one fault message can be stored with respect to
any fault event on the SIMOREG 6RA70, only indices 1, 9, 17, 25, 33, 41,
49 and 57 are relevant.
A fault value is assigned to each fault number in the corresponding index of
parameter r949. This provides further information about the nature of the
fault.
In addition, the fault time (the current reading of the hours run counter as
the fault occurred (r048)), is stored for each fault in r049. The data for the
current (not yet acknowledged) fault are stored as the "Hours run counter
reading" in index 1. The data for earlier, already acknowledged faults are
stored under the following indices.

Plaintext information about the fault numbers is available under the
corresponding index of parameter r951.
r949
Fault value
Fault value of faults, allows more detailed diagnosis for a variety of
(G189)
parameters.
The fault values are stored in the same indices as the associated fault
numbers (r947) - see parameter r947.
