The units of the bits 0 to 4 are coded.
Bits 6 and 7 describe the validity range of a value. Bit 5 is reserved.
The complete byte is calculated from the sum of the unit and the range of validity.
Attention!
If the unit byte refers to CODE, the recorded value or status will result in a text message. The content of this text
message is listed in the table on Seite 28 or Seite 30. The floating point value contains an internal CODE but no
valid measured value.
