Changing of Output Characteristics

The output characteristics can be changed using sequence programs in FX
5.1 Example: Changing of Voltage Output Characteristics
This section describes an example of a program that can change the digital value range from 400 to 2000
(when analog output range is 1 to 5 V) to 0 to 10000.
A specified digital value is inputted into D100.
