MODEL: R3-NF3TRANSMISSION DATA DESCRIPTIONSThe DIP SW in the front of the module specifies I/O points, I/O type and with or without of I/O module status data setting.
I/O DATA is assigned data allocation setting from module 1 orderly.
The data of I/O module out of the setting area is invalid.
When there is I/O module status data, use the data area of the last 2 words of the input data area as the status data. When thestatus data and I/O data overlap, the status data takes precedence.
For example, when the number of I/O points is “16” and SW1 and SW2 are set as shown below.

Status data cannot be assigned because there is no input data.
For output only, operate without status area.
• Module Status indicates whether individual I/O modules are mounted or not. The bit corresponding to the mounted slot turns to“1,” and the unmounted slot to “0.”• Error Status indicates error status for each module as described below. The bit corresponding to such module turns to “1.”R3-TSx, R3-RSx, R3-US4 (T/C, RTD input): Input burnout
R3-DA16A: Power input in error or disconnected
R3-YSx: Output current error (e.g. load unconnected)
R3-PC16A: External power supply in error or disconnected
Every module which input is less than -15% or more than +115%
R3-US4 (voltage input): out of -10 to +110% input.

MODEL: R3-NF3I/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.
15

0■ 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.
150■ 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.
150■ 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.
150+0Lower 16 bits
15+10Higher 16 bits

■ BCD DATA (32-bit data, models: R3-BA32A, BC32A, etc.)

■ 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.
