Example Application Program #1
Output an analog value in the range of 0 to 10 Volts when the digital value in the user program
is 0 ~ 10000.
D0 ranges from 0 ~10000. To convert D0 to the 0 ~ 4000 value needed for D8114:
D8114 = [D0 x 4000] / 10000 or [D x 2] /5
Example Application Program #2
An output of 0 ~ A [ 0 < A < 10] is desired in the program that is using a digital range of 0~4000
that is stored in register D10.
Because A is smaller than 10 Volts, the digital value of 0~4000 must be converted to a value of
0~A’ as shown in the graphs above. 4000/10V = A’/A or A’ = [4000/10] x A = 400 x A
D8114 = [A’] x (D10 / 4000) = [400 x A] x [D10 / 4000) = (A x D10) / 10.
If A = 8

Ch1 is set for the voltage input (0 to 10V).
Ch2 is set for the current input (4 to 20mA).
The digital value gained through AD conversion of Ch1 is stored at D0.
The digital value gained through AD conversion of Ch2 is stored at D2.
