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]}
