Scale Modbus PV to Engineering Units (SCALE)
The Modbus PVs may be scaled to reflect different engineering units than the data read out of the
Modbus slave device register. To do this, use the Scale menu to select the type of scale desired.
Note 1: The bottom display of the feet and inches display models does not show decimal points. While
the decimal point may not appear, it is included on the factor programming steps. For example: To enter a
conversion factor of 2.54, select a factor decimal point with 2 decimal locations, and enter a factor value
of 254.
Note 2:
MP-SCAL is only available when scaling PV1.
Factor (FACTOR)
Factor scaling uses a conversion factor for scaling a number of PV register counts to a single
display count. In other words, the factor acts as a multiplier to change Modbus PV register
data units into display engineering units.
Factor Decimal Point (F.DP)
Enter the number of decimal point locations necessary to enter the conversion factor.
Conversion Factor Value (VALUE)
Enter the conversion factor; the multiplier value that is applied to the Modbus PV register
data to convert it to the desired display engineering units.
For example: if the PV register data is a height in centimeters, but a height in inches is
desired on the display, a factor of 0.393701 would be entered.
(Display Value) = (Modbus Register Value) * (Factor)
