Energy objects can be obtained in two-register fixed point data format and four-register encoded format, not supporting
in floating point data format.
The two-register format is presented in units of kilowatt hours. The four registers encoded
energy object occupies register 3 through register 0. Register 3 is the high order register
and register 0 is the low order register. Register 3 high byte contains value corresponding
to engineering units(power of 10 signed exponent). Register 3 low byte contains a mantissa
multiplier value(power of 2 exponent). Register 3 through register 0 contains a 48-bit energy
mantissa in units of watthours. The data format of four registers is shown.
