LOG
The engineering log
stores
equipment failure
data.
Such
data
is temporarily
stored
in a
five-entry
table
in
core
in
the
following format:
word
87
0
logical unit
1
Day - month -
year
2 Military
time
3 Seconds
1 Error code
4 Hardware
status
Where word 4 is word 12
of
PHYSTB
for
this logic unit.
(This may be a
true
hardware
status
or
a composite
status
formed by
the
logic unit's controller.)
This information (except the
first
word) is
later
stored
on
mass memory in
sectors
so
that
each
sector
holds messages
for one logic unit; i.e., 96/4
or
24
failures
per
device. Each
sector
is filled in wrap-around
style,
which causes
the
sector
to
be
a push down/fall
off
stack.
