Ratio Conversion Function Section 7-8
When Output Signal Range is 0 V to 10 V
The following table shows the correspondence between output signals and
converted scaling values. (The values shown in parentheses are 16-bit binary
data.)
7-7-5 Output Setting Errors
If the analog output set value is greater than the specified range, a setting
error signal will be stored in CIO word n+9 (bits 00 and 01).
Note 1. For the CIO word addresses, n = CIO 2000 + (unit number x 10).
2. The voltage for an output number at which a setting error has occurred will
be output according to the output hold function.
7-8 Ratio Conversion Function
The Analog I/O Unit has a ratio conversion function that enables it to perform
analog-to-analog conversions by itself, without utilizing the PLC. It can use
either Loop 1 (input number 1
→ output number 1), Loop 2 (input number 2 →
output number 2).
Input 1
→ Ratio bias calculation → Output 1
Input 2
→ Ratio bias calculation → Output 2
The relationship between the analog input and the analog output is expressed
by the following conversion equations.

When a setting error is detected
for a particular output, the corre-
sponding bit turns ON. When the
error is cleared, the bit turns OFF.
