1) The wire breakage detection is used in the measuring range 4 ... 20 mA. If the wire breakage detection is
activated in byte 0 and the diagnostic alarm is enabled, a current reduction to below 0.8 mA is indicated.
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.
