So that the inputs are not undefined
after a voltage failure and subsequent
voltage recovery, there is the parameter
“Behaviour of inputs after reset”.
The inputs can either be read i.e. send
read requests to the linked objects
which leads to an increased bus load
or the inputs can adopt default values
which can be defined in the parameters.

Via the “Multiplexer” logic function, the
input data to the output can be controlled
directly. The function has four
communication objects “Controller”,
“Input 1”, “Input 2” and “Output”. The
diagram above indicates the function
of a 1-bit multiplexer (S=Controller,
E1=Input 1, E2=Input 2, A= Output).
The bit size of the inputs and outputs
can be set to 1 byte or 2 byte via the
parameter “Object type input/output”.
The above functionality is thereby retained.
That means that only input 1 is
visible at the output if the control input
has the value “1”. Input 2 is switched
to the output as soon as the control
input has the value “0”.
Note:
The output is only sent when there is
an actual change of the inputs. If e.g.
the control input changes without the
input value changing, the output signal
remains as it is. A new output value
is sent only if an input signal changes.
Multiplier
The “Multiplier” function enables up to
four output telegrams to be sent with
an input telegram. The input communication
object is 1 bit. The output communication
objects can either be 1 bit
or 1 byte. The size is set via a corresponding
parameter.
It can be defined via the setting “Starting
conditions” whether a duplication
of an input telegram should be triggered
after an ON or OFF telegram. Moreover,
there is the possibility of sending
output telegrams with a time
delay. By default, a delay of 1 s is defined.
The useful information (values) which
should be sent with the output telegrams
can be set individually for each
output via a corresponding parameter.
For 1-bit outputs, this is “On” or “Off”
while for 1-byte outputs, values between
“0” and “255” can be assigned.
Gate
With the “Gate” logic function, it is possible
to filter specific signals and to
disable the signal flow temporarily.
The function has three communication
objects “Control input”, “Input” and
“Output”.
The control input or output can be
1 bit, 4 bits, 1 byte or 2 bytes. The object
types for input and output can
also be set to “unassigned”. This means
that the bit size can be freely assigned.
The first internal or external
group address which is assigned and
is already linked with another communication
object defines the size.
The control is always carried out from
input to output provided that this is
permitted by the control input. The activation
via the control input can be
carried out via an ON or an OFF telegram.
If the setting “Control input” is
set to “ON telegram” for example, only
telegrams from the input to the output
are routed if a “1” has previously been
received at the control input.
For 1-bit input and output objects, it
can be set whether the input signals
should be saved or not “During the
blocking”. If the setting “Store input
signal” is selected, the output sends
its value if a telegram has been received
at the input during the blocking.
If the input and output objects are
1 bit, it is possible to invert the output.
An inversion element can therefore be
implemented by a gate.
It is also possible to block signals via
the “Filter function” setting. The following
settings are possible: “Filter not-
