Mapping of DetailedQuality

The value of DetailQuality is mapped to a DetailedQuality bitmap.

Example:
DetailQuality = 1d = 00000001b > overflow = true
DetailQuality = 16d = 00010000b > failure = true

Analogue value (AnalogueValue)

Analogue values are always presented as 32-bit float values (VT_R4) so that the .f and
.i extensions are discarded from the attribute names to simplify the OPC namespace. If
a device only supports integer values, the value is converted to a floating point present-
ation of the value according to its configuration and the following formula, refer to
3.2.6, Configuration of analogue value (ScaledValueConfig).
