The higher the smoothing is selected, the more stable the smoothed analog value is and the
longer it takes until the smoothed analog signal is applied after a unit jump.
Note
After start-up, short circuit, wire break or other channel fault, the smoothing is restarted.
If, for example, the smoothing is parameterized with 16 conversion cycles and all channels are
active, then, with a set interference frequency suppression of 50 Hz, it takes up to 2400 ms until
the process value is reported.
Up to the rst valid process value, the peripheral module for the channel reports a value of 0 and
QI = 0.
The following gure shows how many conversion cycles it takes for the smoothed analog value
to be completely available, depending on the congured smoothing. This applies to every signal
change at the analog input.

① k = 4: Weak smoothing
② k = 16: Medium smoothing
③ k = 64: Strong smoothing
5.4.8 HART gate
Denition
This parameter is used to enable the HART communication for the I/O module.
The "HART gate" parameter acts as a fail-safe "main switch" for the complete module.
