Range of
values:
1 (no smoothing)
4 (weak smoothing)
32 (medium smoothing)
64 (strong smoothing)
No parameter specified: Default 1 (no smoothing ) is valid.
Using the smoothing factor, quickly fluctuating analog values can be
smoothed to a greater or lesser extent (depending on the factor). This may
allow a narrower threshold band to be set (see ThresholdValue).
The smoothing factors are identical to the smoothing factors that are
configured for some S7 analog input modules. The smoothing is handled in
typical using the same formula as for input modules, described by the
following:

k = smoothing factor
Note
When MeanValueGeneration = TRUE, i.e. the analog values are sent as mean values, the
SmoothingFactor parameter has no meaning.
