Blocking
object
As
well
for
grouped
channels
as
for
unique
channels
the
blocking
object
can
be
activated.
At
the
unique
channels
one
blocking
object
for
every
channel
can
be
activated.
For
grouped
channels,
you
can
activate
one
blocking
object
for
both
channels.
The
communication
object
for
a
channel
appears
as
soon
as
it
is
activated
for
a
channel.
At
a

there
are

to
4
blocking
objects

able.
The
corresponding
channel
of
the
blocking
object
is
blocked
by
sending
a
logical
1.
A
blocked
channel
is
not
controllable
as
long
as
it
is
blocked.
By

Table

Parameter
Channels
grouped
By
choosing
channels
as
grouped,
two
channels
become
one
common
function.
The
grouped
function
is
called
dual
surface,
dual
surface
dimming,
and
dual
surface
shutter.
In
contrast
to
the
single
surface
functions,
one
action
can
be
performed
independent
form
the
other
one.
One
input
performs
always
one
function.
The
assignment
for
the
inputs
can
be
made
individually,
so
it
is
possible
to
configure
which
input
should
for
example
drive
the
shutters
up
and
which
down.
