Ratio Conversion Function
Section 7-8
Positive Gradient
Conversion
(Analog output) = A x (Analog input) + B
A: Ratio set value
0 to 99.99 (BCD)
B: Bias
8000 to 7FFF (16-bit binary data)
The following example is for an I/O range of –10 to 10 V.
Constant A:
0050 (0.5)
Constant B:
0190 (2.0 V)
Analog input:
–10 to 10 V
Analog output
= 0.5
×
(–10 to 10 V) + 2.0 V
= –3.0 to 7.0 V
Note
The scaling function cannot be used simultaneously with the ration conversion
function.
Negative Gradient
Conversion
(Analog output) = F – A x (Analog input) + B
F: Output range maximum value
A: Ratio set value
0 to 99.99 (BCD)
B: Bias
8000 to 7FFF (16-bit binary data)
The following example is for an I/O range of 0 to 10 V.
Constant A:
1000 (10.0)
Constant B:
0068 (0.5 V)
F:
10 V (output range maximum value)
Analog input:
0 to 1 V
Analog output
= 10 V – 10
×
(0 to 1 V) + 0.5 V
= 10.5 to 0.5 V
