Memory Floating Point:
Note:
Returned as 15bit plus sign 2s complement with +/- 5% over/underrange applied. Consider
over/underrange when scaling values to be displayed at the workstation. The following equation may be
used to determine a value for display.
Display Value = MODBUS Value [ (Span Value -Zero Value) 1.1] + {Zero Value - [(Span Value - Zero Value) .05]}

Memory Reals:
Note:
Real value represents float value without the decimal point such as 123.4 is returned as 1234.
Decimal devisor is returned as 1, 10, 100, or 1000 for decimal position of 1, 2, 3, or 4, where 123.4 would
return the value 10.
