Basic Program Example
Create the following basic program example to output D/A converted analog data.
The following program will set the 1st board to the voltage output mode and 2nd board to current output
mode, and will set digital data in D100 and D101 for D/A conversion.
The following program will set the 1st board to the voltage output mode and 2nd board to current output
mode, and will set digital data in D100 and D101 for D/A conversion.
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 D100 and D101.
