The following program will set channel 1 of the 1st adapter to voltage input mode and channel 2 to current
input mode, and will store the converted A/D value of channel-1 data into D100 and that of channel-2 data
into D101. The program will also set "voltage output" for output channels, and set the digital D/A
conversion output to D102.

Even if the input data is not stored into D100 or D101, the data registers D8260 or D8261 can be directly
used in the timer/counter setting value or in a PID instruction.
Using the indicator or the sequence program, input the digital data to be subject to D/A conversion (to be
output as analog data) in D102.
