1.
The
setting
option
for
the
debounce
time
is
for
debouncing
of
the
input
signals
from
mechanical
switches
2.
The
parameter
“Time
for
keystroke
long”
allocates
a
static
value
to
the
universal
interface
from
when
a
long
keystroke
is
recognized.
This
parameter
is
important
for
functions,
which
have
different
functions
for
a
long
and
a
short
keystroke.
3.
The
parameter
“
Behavior
at
bus
power
up”
defines
the
behavior
of
the
universal
interface
at
a
bus
power
return.
The
setting
“Read
value
for
toggle”
effects
that
all
communication
objects
“value
for
toggle”
are
read.
So
the
Input
knows
the
current
status
of
the
objects.
If
you
choose
the
setting
“no
read
value
for
toggle”,
the
input
will
not
know
the
current
status
of
the
actor.
So
the
input
assumes
an
unconfirmed
value
for
the
objects
“value
for
toggle”
and
sends
always
a
“0”
‐
signal
at
the
next
operation.
Only
now
the
input
knows
the
status
of
the
actor
and
can
send
the
right
values.
But
if
you
choose
the
read
of
these
values
at
a
bus
power
up,
the
input
will
send
immediately
the
right
value
for
toggling.
