5.3.2 Example Application Program 2
In current input mode, the 2AD converts analog values from 4 ~ 20mA to the digital output of 0 ~ 2000. If
using a digital range of 4000 ~ 20000 in the program, the range must be converted from 0 ~ 2000 to 4000
~ 20000 as shown in the programming example below. Digital values that are converted from analog
values are stored in D8112 or D8113.
The analog input does not have exact resolution of 8 μA because the digital value is converted from a
range of 0 ~ 2000 to 4000 ~ 20000.

If a digital value in the range of 4000 ~ 20000 is used in D60, please see below.
Digital value used in user program: D60 = 8 × (D8112 or D8113) + 4000
