FP2 Analog Unit
Sample Program of Analog Input Offset Setting
11 - 3
11.1 Sample Program (CPU Unit with Analog I/O)
11.1 Sample Program (CPU Unit with Analog I/O)
Program outline
This program offsets 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 by the set numerical amount only,
and then reads it to the data registers DT100 to DT102 using the preparation completion
flag.

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).
By the move instruction F0
(MV), the contents of input
relay area WX0 to WX2 are
read to the data registers
DT100 to DT102.
