TRANSMISSION DATA ASSIGNMENTS
DIP SW located at the side of the module specifies each I/O module’s data allocation (occupied data area).
For example, when the data areas are assigned as shown below:
Module 1
4
Module 2
4
Module 3
4
Module 4
1
Module 5
1
Module 6
1
Module 7
1
Then the I/O data are assigned as in the table below:
ADDRESS
POSITION
ADDRESS
POSITION
Input Registers (3X)
Holding Registers (4X)
1 – 4, 257 – 264
Slot 1
Coil (0X)
Inputs (1X)
1 – 64
Slot 1
5 – 8, 265 – 272
Slot 2
65 – 128
Slot 2
9 – 12, 273 – 280
Slot 3
129 – 192
Slot 3
13, 281 – 282
Slot 4
193 – 208
Slot 4
14, 283 – 284
Slot 5
209 – 224
Slot 5
15, 285 – 286
Slot 6
225 – 240
Slot 6
16, 287 – 288
Slot 7
241 – 256
Slot 7
For Coil (0X) and Inputs (1X), addresses 16 times assigned data areas (Data Allocation Type) are allotted with the Data Al-
location Type ‘1’ and ‘4.’ With ‘8’ and ‘16,’ 64 (4 × 16) are automatically assigned.

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). Negative percentage is represented in 2’s
complements.
0
15
■
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.
