Please test the first two (Quality) to check the quality of the measuring value:
Good (non Cascade) measuring value is ok and can be used
Uncertain the measuring value can be used, although the accuracy is not
confirmed (e. g. measuring value is frozen or A/D-value is outside
of the valid range)
Bad the measuring value is not acceptable and cannot be used for
further processing.
Good (Cascade) will not be supported, because it is not applicable for the device
Diagnosis
If the internal diagnostic detects a error, additional information will be transmitted in the
Master. The meaning of this information are described in the GSD-file under
UNIT_DIAG_BIT(i).
