Definition of the status

Status byte
The status is used to provide information about the quality of the input and output values. This
information is classified into four stages. Quality stages such as "Bad", "Uncertain", "Good"
and "Good (cascade)" are accompanied with further information. In this case, it deals with the
sub-status and the limit bits. The status byte has the following structure:
Quality
Limit bits
The meaning of the sub-status depends on whether the condensed status is activated or not.
The sub-status is therefore specified separately for both the cases.
