11.2 Sample Program (Analog Input Unit)
11.2 Sample Program (Analog Input Unit)
Program outline
This program offsets the analog input data for ch 0 to ch 4 (set for no execution of input
conversion processing) of the analog input unit by the set numerical amount only, and
then reads it to the data registers DT100 to DT104 using the preparation completion flag.

Offset change
By the move instruction
F0 (MV), the contents of
input relay area WX0 to
WX4 are read to the data
registers DT100 to DT104.
Offsets the analog values that were read by the numerical value set in shared
memory only, and stores it in the conversion value area (input relay area).
Settings
Channels that execute analog input conversion processing
H1111: ch 0 to ch 3 are set for execution
H1: ch 4 is set for execution and ch 5 to ch 7 are not set for execution
I/O allocation
I/O number
