Smoothing
The individual measured values are smoothed using filtering. The smoothing can be set in 4
levels.
Smoothing time = number of module cycles (k) x cycle time of the module.
The following figure shows the number of module cycles after which the smoothed analog
value is almost 100%, depending on the set smoothing. It is valid for each signal change at
the analog input.
