I/O DATA DESCRIPTIONS
The data allocations for typical I/O modules are shown below.
Refer to the manual for each module for detailed data allocations.
■ ANALOG DATA (16-bit data, models: R3-SV4, YV4, DS4, YS4, US4, etc.)
16-bit binary data.
Basically, 0 to 100% of the selected I/O range is converted into 0 to 10000 (binary).
-15 to 0 % is a negative range represented in 2’s complement.
In case of R3-US4, -10 to 0% is a negative range represented in 2's complement.

■ TEMPERATURE DATA (16-bit data, models: R3-RS4, TS4, US4, etc.)
16-bit binary data.
With °C temperature unit, raw data is multiplied by 10. For example, 25.5°C is converted into 255.
With °F temperature unit, the integer section of raw data is directly converted into the data.
For example, 135.4°F is converted into 135.
Minus temperature is converted into negative values, represented in 2’s complements.
