Using
the
Compact
Flash
Using
the
Compact
Flash
Card
A
2
Gigabyte
Compact
Flash
card
is
pre
‐
installed
inside
the
Digital
Electronics
Enclosure
and
is
located
inside
the
enclosure
on
the
reverse
side
of
the
HMI
touch
screen.
Run
data
is
stored
on
the
Flash
Drive
but
only
when
the
TOP.RUN
page
is
currently
displayed.
The
internal
data
logger
operates
using
two
separate
processes.
The
first
samples
each
data
point
at
the
rate
specified
by
the
factory
(1/second),
and
places
the
logged
data
into
a
buffer
within
the
RAM
of
the
panel.
The
second
process
executes
every
minute,
and
writes
the
data
from
RAM
to
the
Compact
Flash
card.
Note
that
because
data
is
not
committed
to
the
Compact
Flash
for
a
min
‐
ute,
this
amount
of
log
data
may
be
lost
when
the
terminal
is
powered
‐
down.
Further,
if
the
terminal
is
powered
‐
down
while
a
write
is
in
progress,
the
Compact
Flash
card
may
be
cor
‐
rupted.
Data
is
being
written
to
the
Compact
Flash
card
when
the
middle
yellow
LED
light
on
the
front
of
the
HMI
panel
is
flashing.
Do
not
turn
the
power
off
or
remove
the
Compact
Flash
while
the
yellow
LED
is
blinking!
Removing
the
Flash
Card
The
process
for
removing
the
Compact
Flash
card
is
called
Hot
Swapping.
Hot
Swapping
is
not
the
preferred
method
of
transferring
data
from
the
flash
card
to
an
external
source
due
to
the
possibility
of
data
files
being
corrupted
if
the
Flash
card
is
removed
improperly.
Please
remember
that
the
Compact
Flash
card
cannot
be
removed
while
data
is
being
written
to
the
Flash
card,
or
when
the
yellow
LED
is
flashing.
To
Hot
Swap,
go
to
the
TOP.COM
page
by
pressing
the
COM
button
from
the
main
menu.
Next,
press
the
Remove
CF
button
and
finally,
press
the
SAFELY
REMOVE
COMPACT
FLASH
button.
When
the
‘Safe’
prompt
is
indicated,
you
may
safely
remove
the
Compact
Flash
card.
Open
the
Electronics
Enclosure
and
remove
the
Flash
card
from
the
back
of
the
HMI
panel
in
the
door
of
the
Electronics
Enclosure.
