installation instructions

V05.2012
Any
OPC
client
can
connect
the
OPC
server
to
access
the
values
for
all
the
CIATControls
available
on
the
system
and
declared
on
the
server.
Notes:
Other
actions
are
possible
from
the
OPC
server
configurator:
‐
"MODIFY":
used
to
modify
the
name
or
IP
address
of
the
equipment
‐
"DELETE":
used
to
delete
the
equipment
‐
"REFRESH":
used
to
start
a
ping
for
all
the
equipment
on
the
list
‐
"SETTINGS":
used
to
configure
the
OPC
server
parameters
The
"SETTINGS"
menu
is
used
to
modify
the
following
parameters:
‐
Boolean
value
is
true
:
applies
to
all
OPC
items
created
with
the
bool
type;
if
the
box
is
checked,
the
value
coded
for
true
is
1;
if
the
box
is
not
checked,
it
is
‐
1.
‐
Reconnect
every
:
frequency
of
reconnection
to
a
station
declared
absent
on
the
network.
When
a
station
is
declared
absent
after
a
loss
of
communication,
the
OPC
server
uses
this
frequency
to
check
that
the
station
has
returned
to
the
network
‐
Refresh
time
:
waiting
time
activated
with
each
event
prior
to
station
update.
This
is
used,
for
example,
when
adding
items
to
the
station
for
monitoring:
it
is
used
to
send
the
list
of
items
to
be
monitored
once
all
the
items
have
been
declared,
rather
than
updating
the
station
each
time
an
item
is
added/deleted.
In
particular,
this
saves
time
when
initialising
the
OPC
server
‐
Disconnection
time
:
waiting
time
prior
to
disconnection
of
the
link
between
the
OPC
server
and
the
station
for
which
no
items
are
read
by
the
OPC
server
‐
Dataserver
test
frequency
:
cyclical
test
to
check
for
the
presence
of
the
station
(use
of
the
ping
command)
‐
TCP
timeout
:
configuration
of
the
timeout
period
on
the
TCP
control
when
checking
for
the
presence
of
the
station
on
the
network
‐
Native
type
is
string
:
applies
to
OPC
items
for
which
the
type
is
defined
as
string
if
the
box
is
checked.
Otherwise
the
type
is
undefined
‐
Address
separator
:
character
used
to
separate
the
different
fields
of
the
OPC
address
(device
field,
network
field,
variable
field,
etc.)
4.
USE
The
OPC
server
launches
automatically
when
an
OPC
client
attempts
to
communicate
with
the
CIAT.CIATControl
OPC
Server.DA
server.
Any
OPC
client
can
now
select
the
items
he
wishes
to
monitor
(see
sections
7
to
10
for
the
items
available
for
each
type
of
equipment).
The
OPC
server
has
the
following
buttons:
‐
Stations…
:
used
to
check
the
stations
interrogated
by
the
OPC
client;
it
is
possible
to
refresh
the
connections
or
attempt
to
reconnect
if
there
is
a
loss
of
communication
with
one
of
the
stations.
