4.8 Basic Program Example
Create the following basic program example to read out analog conversion (A/D conversion) data.
• For FX Series PLC
3G
The following program will set the board A 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.
