Logic
sub
‐
function
switch
The
sending
condition
adjusts,
when
the
binary
input
should
send
a
signal
on
the
bus.
By
adjusting
the
sending
condition
“change
of
input”,
the
binary
input
sends
a
signal
at
every
change
of
any
input
whether
that
causes
a
change
of
the
logic
operation
or
not.
The
setting
“change
of
output”
causes
that
the
binary
input
sends
only
a
signal
when
the
logic
changes
its
current
status.
The
sub
‐
function
Output
inverted
indicates
whether
the
output
signal
should
be
issued
inverted
(that
means
reversed
1
‐
>0
and
0
‐
>1)
or
normal.
The
following
diagram
shows
the
logic
operation
switch
as
an
and
‐
function.
The
logic
reads
in
this
example
the
channels
A
and
B
as
well
as
an
external
logic
object.
The
Output
is
inverted:
