communication
objects
absolute
position
The
usage/function
of
this
communication
objects
are
explained
at
the
following
segments.
4.3.1
Driving
to
reference
The
shutter
actuator
calculates
its
actual
positions
from
the
appointed
times
for
movement.
The
real
times
for
movement
can
be
corrupted
trough
outside
influences
after
some
time.
A
driving
to
reference
calculates
the
appointed
time
for
movements
anew
and
specifies
in
this
way
the
shutter
actuator
new
times
for
movement.
Based
on
these
new
times
for
movement
the
shutter
actuator
can
calculate
the
real
position
of
the
shutter/blinds
more
detailed.
The
driving
to
reference
is
especially
useful
if
someone
works
very
often
with
commands
for
absolute
positions.
Therefore
the
shutter
actuator
can
calculate
the
entered
position
more
detailed
and
drive
to
this
position
more
precise.
The
reference
run
is
started
through
an
1
‐
signal
on
its
1
bit
communication
object
“start
driving
to
reference”.
It
is
possible
to
adjust
the
reaction
after
the
driving
to
reference
by
the
parameter
“reaction
after
driving
to
reference”.
The
shutter
actuator
can
drive
to
the
position,
which
it
had
before
the
reference
run,
by
the
setting
“drive
to
former
position”.
Through
the
setting
“no
reaction”
the
shutter
actuator
lets
the
shutter/blinds
at
the
position,
which
was
reached
after
the
end
of
the
reference
run.
After
every
transfer
of
a
new
parameterization
you
have
to
conduct
a
reference
run.
This
can
either
manual
occurred,
that
means
the
upper
and
lower
position
are
approached
ones,
or
by
the
object
“start
driving
to
reference”.
Now
the
reference
run
was
conducted
and
the
shutter
actuator
knows
its
actual
state
along
the
driving
range.
4.3.2
Commands
for
absolute
positions
By
the
objects
for
absolute
positions
you
can
specify
a
constant
value
to
the
shutter
actuator,
on
which
the
shutter
shall
be
driven.
This
value
is
indicated
in
percent
and
has
a
range
from
0
‐
100%
with
every
1%
step
between
it.
From
the
indicated
percent
value
the
shutter
actuator
calculates
at
the
next
step
the
real
time
for
the
movement
of
the
shutter/blinds
based
on
the
appointed
times
for
movement
and
the
actual
position.
The
commands
for
the
absolute
position
are
transmitted
to
the
1
byte
communication
objects.
There
is
an
object
for
the
absolute
height
positions
of
the
driving
way
at
shutter
and
blinds.
Additional
there
is
an
object
for
the
opening
angle
of
the
blinds
at
shutters,
the
object
“absolute
position
of
blinds”.
At
the
percentage
description
corresponds
0%
always
fully
opened
and
100%
full
closed.
4.3.3
Status
objects
(actual
position/direction)
The
status
objects
“Status
actual
position”
and
“Status
act.
position
of
blinds”
conduce
the
visualization
of
the
absolute
position.
Both
objects
indicate
the
actual
state
of
the
height
and
the
opening
angle
of
the
blinds,
respectively
after
end
of
driving.
The
objects
can
be
used
e.g.
for
Visualization.
