Basic Program Example

Create the following basic program example to read out analog conversion (A/D conversion) data.
• For FX , FX
3G
The following program will set channel 1 of the 3rd
input mode, and will store the converted A/D value of channel-1 data into D100 and that of channel-2 data
into D101.
M8001
M8000
M8000
M8002
Initial

M8000
Even if the input data is not stored into D100 or D101, the data registers D8280 or D8281 can be directly used
in the timer/counter setting value or in a PID instruction.
