Energy format
Energy objects in the mMINT are supported in 2-register fixed point
object format and a 4-register power/mantissa format . These objects
do not support IEEE floating point format .
The 2-register format is presented in units of Kwatthours and
is valid for INCOM products reporting energy in watthours or
Kwatthours only . Products reporting in units greater than Kwatthours
(e .g ., Mwatthours) could not guarantee consistent Kwatthour
resolution up to and through their rollover values .
All products reporting energy (independent of energy units) support
the energy objects occupying four registers—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 a value corresponding to Engineering
Units (power of 10 signed exponent) . Register 3 low byte contains a
Mantissa Multiplier value (power of 2 signed exponent) .
Register 2 through register 0 contains a 48-bit energy mantissa in
units of watthours . Net and total energy objects are signed values .
All other energy objects are unsigned values .
The data format of these four registers is given in
Figure 9
