1) The function is not available for the modules 4×analog input ±10V and 4×analog input ±20mA.
2) The conversion speeds given are valid for the operation of an analog input. When operating several inputs, the
corresponding conversion speed must be divided by the number of active inputs to detect the conversion speed
per input.
Please note that due to shorter integration times the resolution is reduced at higher conversion speeds. The data
transfer format remains the same. Only the lower bits (LSBs) no longer are relevant for the analog value.
