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.
Table C- 2 Smoothing time depending on the set smoothing level and interference frequency suppression

Medium
Strong
Cycle time
The cycle times (1 ms, 1.04 ms and 1.25 ms) result from the configured interference
frequency suppression. The cycle time is independent of the number of configured analog
channels. The values for the analog input channels are detected sequentially in each cycle.
