For test, simulation and programming.
Scaling help you scale raw values to human readable values.
Scaling works only for signed and unsigned 16/32 bit integers
Enable: Must be enabled to scale the value from the Modbus server/slave. Scaling is automatically disabled if other than a 16/32 bit integer display format is selected.
(X1,Y1) and (X2,Y2):A line passing through the two points (X1,Y1) and (X2,Y2)
Slope = m = (Y2 - Y1) / (X2 - X1)
Line equation: Y = m * (X - X1) + Y1
Precision: Number of digits after the decimal point.
