The
blocking
function
gets
active,
when
the
corresponding
communication
object
becomes
a
logical
“1”.
By
sending
a
logical
“0”,
the
blocking
function
can
be
deactivated
again.
The
parameter
“Behavior
when
locked”
defines
an
action
for
the
output
at
activating
the
blocking
process.
There
are
the
setting
on,
off
and
no
change
available.
The
same
settings
are
also
available
for
the
“Behavior
when
unlocked”.
This
action
is
called
when
the
blocking
function
is
deactivated
again.

The
following
diagram
describes
the
blocking
process.
For
the
“Behavior
when
locked”,
the
action
on
was
parameterized
and
for
the
“Behavior
when
unlocked”
the
action
off
was
parameterized:
The
KNX
telegram
shows
which
values
are
send
to
the
blocking
object.
By
sending
a
logical
“1”,
the
blocking
function
is
activated
and
the
channel
is
switched
on.
The
blocking
function
is
deactivated
again
by
sending
a
logical
“0”.
So
the
channel
is
switched
off.
