10.1 Sample Program (CPU Unit with Analog I/O)
Program outline
After averaging the analog input data for ch 0 to ch 2 (set for no execution of input
conversion processing) of the CPU unit with analog I/O, this program reads the averages
to the data registers DT100 to DT102 using the preparation completion flag.

Averages the analog values that were read
and stores the averages in the conversion
value area (input relay area).
By the move instruction F0 (MV), the
contents of input relay area WX0 to
WX2 are read to the data registers
DT100 to DT102.
