10.2.3.2 Real-time data object register
Data that is subject to real-time changes, such as current, voltage and
energy, can be requested via sub index: 0 and indexes according to
Real-time data can be obtained either in IEEE floating-point or fixed-point
format. For data displayed in fixed-point format, each result is presented as a
multiplication of the real-time data with a scaling factor. Energy objects can
only be obtained in fixed-point format.
Registers for which the IEEE floating-point value is not specified are only
supported in fixed-point format (FP).
