5.4 Scale Conversion Function
■
Overview of the function
● This function is to scale-convert analog input values to an easy-to-use data range.
● When the minimum value and the maximum value are set, analog input values are converted
to digital values in the range between the minimum and maximum values as the full scale.
● The data after scale conversion is stored in the I/O mapping.
● The function can be used for unit conversion, etc.
● Scale conversion processing is executed on a channel-by-channel basis.
● Conversion values read from the analog input unit are numbers including fractions. Therefore,
convert the values to easy-to-handle figures if needed.

Scale conversion processing
Voltage input range: Scale conversion when the input range of 1 to +5 V is converted to a scale
between the minimum value of 0 and the maximum value of +10000
● The input value ranges from the minimum scale value -2% to the maximum scale value +2%.
● If data outside this range is input, scale conversion will be disabled. The the minimum scale
value -2% or the maximum scale value +2% will be stored as a converted value.
