If the diagnostic alarm is enabled in byte 0, diagnostic data are transmitted to the master via the emergency
telegram in the event of an error.
2)
The conversion speeds given are valid for the operation of an analog input. When operating several inputs, the
corresponding convervion speed must be divided by the number of active inputs to detect the conversion speed
per input.
Please note that the resolution is reduced with higher conversion speeds due to shorter integration times. The
data transfer format remains the same. Only the lower bits (LSBs) are not relevant anymore for the analog value.
3)
The function is not available for the modules 4xanalog input ±10V and 4xanalog input ±20mA.
