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 communicati-
on objects can either be 1 bit or 1 byte.
The size is set via a corresponding pa-
rameter.
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 is 1 bit and the input
and output objects are likewise 1 bit
by default. The object types at the
input and output can also be set to
“not assigned”. That 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 se-
lected, the output sends its value if a
telegram has been received at the input
during the blocking.
