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 and 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 and 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 con-
verted into 135.
Minus temperature is converted into negative values, represented in 2’s complements.

■
ANALOG DATA (16-bit data, models: R3-CT4A, CT4B, etc.)
16-bit binary data.
Integer obtained by multiplying unit value (A) by 100.
In case of CLSE-R5, integer obtained by multiplying unit value (A) by 1000.

■
ACCUMULATED COUNT DATA (32-bit data, models: R3-PA2, PA4A, WT1, WT4, etc.)
32-bit binary data is used for accumulated counts and encoder positions.
Lower 16 bits are allocated from the lowest address to higher ones, higher 16 bits in turn.

Higher 16 bits
■
BCD DATA (32-bit data, models: R3-BA32A, BC32A, etc.)
32-bit binary data is used for BCD.
Lower 16 bits are allocated from the lowest address to higher ones, higher 16 bits in turn.

■
ANALOG 16 BITS BCD DATA
The display range is -7999 to +7999. Change data within display range with configurator software (model: R3CON).
■
ANALOG 32 BITS BCD DATA
The display range is -1500 to +11500. Data allocation of module is doubled as usual. Pay attention I/O type.
