Digital In- and Outputs

6.3.5 Digital Filter (di.0)

6.3.6 Inverting of the
Inputs (di.2)

6.3.7 Edge Triggering

(di.14)
Edge triggering has no
influence on the control
release (ST) as this is only a
static signal.

As shown in picture 6.3.4it can be selected with parameter di.15 , if the inputs are
switched by the terminal strip (standard) or with parameter di. 16 . Both of the
parameters are bitcoded, i.e. according to the following table, the corresponding
value of the input must be set. In case of several inputs add up the sum. (exception:
control release must always be bridged at the terminal strip).

The digital filter reduces the sensitivity against disturbances on the digital inputs.
With parameter di.0 a reaction time is adjusted. For the duration of the adjusted time
the status of all inputs must remain constant. The acceptance takes place at the
rising edge. (see picture 6.3.7). At RST with the falling edge!
Parameter Setting Range
di.0 0...31
It can be adjusted with parameter di.2 if a signal is 1- or 0 active (inverted). The
parameter is bitcoded, i.e. according to the following table, the corresponding value
of the input must be set. If several inputs shall be inverted add up the sum (exception:
inverting of the control release is without function).
It is standard that the inverter is controlled by static signals, i.e. an input is set as long
as there is a signal. However, in practice it can happen that a signal is available only
for a limited time, but the input shall remain set. In that case the input can be set to
edge triggering. A rising edge with a pulse time > response time of the digital filter is
then enough for a start. Switch off with the next rising edge.
