Smoothing
The individual measured values are smoothed by filtering. The smoothing can be set in 4
levels and channel-selective in STEP 7 (TIA Portal).
Smoothing time = Smoothing (k) x configured integration time
The following figure shows the time it takes for the smoothed analog value to reach
approximately 100 % depending on the set smoothing. This is valid for all signal changes at
the analog input.
①
None (smoothing = 1 x integration time)
②
Weak (smoothing = 4 x integration time) *
③
Medium (smoothing = 16 x integration time) *
④
Strong (smoothing = 32 x integration time) *
* The smoothing time can increase by 1 x integration time.
Figure C-5 Smoothing time depending on the set smoothing level
The following table shows the time it takes for the smoothed analog value to reach
approximately 100 % depending on the set smoothing and the set interference frequency
suppression.
