Name	Type	Description
lrValue	LREAL	Final value determined from the raw data.
lrPrefix	LREAL	Sign and division (+/- and e.g. 0.1).
sUnit	STRING	Unit.

byValueH	BYTE	High-byte of the measured value.
byValueL1	BYTE	Low-Byte
byValueL2	BYTE	Low-Byte
byValueL3	BYTE	Low-Byte
byInfoHead	BYTE	Scaling information
byUnitIndex	BYTE	Sign and unit – coded.
byZeroH	BYTE	Zero point in the case of normal range zero-point scaling OR high-byte zero point in the case of extended scaling.
byRangeZeroL	BYTE	Range in the case of normal range zero-point scaling OR low-byte zero point in the case of extended scaling.
