8 PCIE-5565PIORC Reflective Memory Board
Overview
The
PCIE
‐
5565PIORC*
is
a
PCI
Express
(PCIe)
member
of
GE’s
family
of
Reflective
Memory
real
‐
time
fiber
‐
optic
network
products
that
supports
both
low
profile
and
standard
height
PCIe
boards.
Two
or
more
PCIE
‐
5565PIORCs,
along
with
other
members
of
this
family,
can
be
integrated
into
a
network
using
standard
fiber
‐
optic
cables.
Each
board
in
the
network
is
referred
to
as
a
“node.”
Reflective
Memory
allows
computers,
workstations,
PLCs
and
other
embedded
controllers
with
different
architectures
and
dissimilar
operating
systems
to
share
data
in
real
time.
The
5565
family
of
Reflective
Memory
(referred
to
as
RFM
‐
5565
in
this
manual)
is
fast,
flexible
and
easy
to
operate.
Data
is
transferred
by
writing
to
memory
(SDRAM),
which
appears
to
reside
globally
in
all
boards
on
the
network.
Onboard
circuitry
automatically
performs
the
data
transfer
to
all
other
nodes
with
little
or
no
involvement
of
any
host
processor.
