Smoothing of the Measured Values
You fill find information that is generally applicable to the smoothing of analog
values in Section 5.6.
The following figure indicates for the module the number of module cycles after
which, in the case of a step response, the smoothed analog value is applied at
almost 100%, depending on the smoothing setting. The figure applies to every
change of signal at an analog input.
