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 after how many module cycles the smoothed analog value is
almost 100%, depending on the set smoothing. Is valid for each signal change at the analog
input.
①
None (k = 1)
②
Weak (k = 4)
③
Medium (k = 16)
④
Strong (k = 32)
