Explanation: Using the smoothing factor, quickly fluctuating analog values can be
smoothed to a greater or lesser extent depending on the parameter setting.
It may then be possible to set a lower value for the send trigger

The smoothing factors are identical to the smoothing factors that are
configured for some S7 analog input modules. The smoothing in the
channel functions according to the same formula as on an input module:

Explanation: Transmission of an analog value located in the overflow or underflow range
(7FFFh or 8000h) is suppressed for the time period specified here. The
value 7FFFh or 8000h is only sent after this time has elapsed, if it is still
pending. If the value returns to below 7FFFh or above 8000h again before
this time elapses, it is immediately sent again as normal. The suppression
time is started again for the full duration the next time 7FFFh or 8000h is
received.
This is typically used for temporary suppression of current values that may
occur when powerful motors are started. The analog input may exceed
several times the maximum range under some circumstances. Suppression
prevents these values from being signaled as faults in the control center
system.
The suppression is adjusted to analog values that are acquired by the S7
analog input modules as raw values. These modules return the specified
values for the overflow or underflow range for all input ranges (also for life-
zero inputs).
When the user provides specific values, fault suppression is only possible if
these also adopt the values 7FFFh or 8000h when the permitted ranges
are exceeded. If this is not the case, the parameter does not need to have
a value entered.
