11.3 Built-in analog input function
11.3.8 Program example
Create the following program to read out analog conversion (A/D conversion) data.
The following program will store the converted A/D value of channel-1 data into D100 and that of channel-2
data into D101.
Even if the input data is not stored into D100 or D101, the data registers D8270 or D8271 can be directly used
as timer/counter setting value or in a PID instruction.
The following program will store the converted A/D value of channel-1 data into D100 and that of channel-2

as timer/counter setting value or in a PID instruction.
11.3.9 Changing of input characteristics
The input characteristics can be changed using a sequence program in the PLC.
Example: Changing of input characteristics
This section describes an example of a program that can change the digital output range of 100 to 500 (when
the voltage input is 1 to 5 V) to digital output range of 0 to 10000.
