Functional Description
Digital In- and Outputs
6.3.5
Digital Filter (di.3)
The digital filter reduces the susceptibility to interferences on the digital inputs. With
di.3 a response time is adjusted. For the duration of the adjusted time the conditions
of all inputs must remain constant, so that a transfer occurs. The transfer takes place
at the positive edge of the scanning grid (see Fig. 6.3.7).

6.3.6
Inversion of In-
puts (di.4)
With parameter di.4 it can be adjusted, whether a signal is 1- or 0-active (inverted).
The parameter is bit-coded, i.e. according to the table below, the appropriate value for
the input is to be entered. If several inputs shall be inverted, then the sum is to be
formed. (Exception: An inversion of the control release remains without function).
6.3.7
Edge-triggering
(di.5)
As a standard the inverter is controlled with static signals, i.e. an input is set for as
long as a signal is applied. However, practice has shown that a signal may be available
for a limited time only, but the input shall still remain set. In that case the input or
several inputs can be adjusted to edge-triggering. Then a rising edge with a pulse
duration that is longer than the response time of the digital filter is sufficient for switch-
on. Switch-off is effected with the next rising edge.
Control release (ST) can be
set to edge-triggering, but
remains without affect on the
function, since it is a pure
static signal.
6.3.4
Terminal Status
(ru.21)
The terminal status shows the logic level on the input terminals. It is unimportant,
whether the inputs are internally active or not. If a terminal is controlled, then the
appropriate decimal value according to the table below is output. If several terminals
are active, then the sum of the decimal values is output.
Example: ST, F and IB are controlled
