Serial Communications Module

(MSR04XI
)
Issue

INTRODUCTION
AND
TEC
HNICAL
DATA
PURPOSE
The
Serial
Communications
Module
provides
a serial
interface
between
the
SC300E
environment
and
a variety
of
remote
devices
complying
with
the
standar
d
RS232
-
C.
At
least
one
Serial
Communications
Module
must
be
used
in
the
system
and
fitted
in
Slot
10
of
the
main
chassis
to
enable
communications
between
the
system
processors
and
the
workstations.
The
workstation
link
is
used
for
loading
the
application
software
and
monitoring
ladder
and
diagnostic
functions.
The
link
utilises
Port
0 of
the
module.
Additional
modules
can
be
fitted
to
any
other
I/O
slot,
‘wrong
slotting’
is
prevented
by
mechanical
coding
blocks
(Figure
2
-
1 ).
The
system
software
identifies
the
module
via
a built
-
in
hardware
identifier.
Circuit
triplication
and
voting
procedures
make
the
module
single
fault
tolerant
and
front
panel
indicators
show
Tx/Rx
activity,
the
circuit
on
-
line
status
and
the
health
of
the
module.
Communications
conne
ctions
are
via
four
identical
ports
on
the
front
panel
(Ports
0 to
3)
and
these
connections
are
duplicated
on
the
field
connector
(J2)
at
the
rear.
A fifth
port
is
for
diagnostic
purposes
only.
The
module
is
compatible
with
‘single
slot
hot
repair’
and
the
front
panel
has
a switch
to
enable
a request
that
the
module
be
taken
off
line.
This
document
is
intended
to
provide
a general
understanding
of
the
function
of
Serial
Communications
Module,
sufficient
to
enable
basic
maintenance
operations
to
be
effected
in
the
field.
