Description of the parameter AI_ADC_sampling_rate_x (x = 1...4):
Via this parameter the sampling rates of the single channels can be set each independent from the
others. The resolution is 1
@
s. The following values are supported:

If a value is transmitted which is not in the list of allowed parameters, it will be rounded to the
next allowed value.
Note:
To achieve a high resolution, it is advisable to use sample-times, which are a multiple
of 20 ms (50 Hz), because that will reduce disturbances caused by the power
frequency!
