TRANSMISSION DATA DESCRIPTIONS

The DIP SW located at the side of the module speci es 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

Input Registers (3X)

Holding Registers (4X)

1 – 4,

257 – 264

Slot 1

5 – 8,

265 – 272

Slot 2

9 – 12,

273 – 280

Slot 3

Slot 2

129 – 192

Slot 3

193 – 208

Slot 4

209 – 224

Slot 5

225 – 240

Slot 6

241 – 256

Slot 7

For Coil (0X) and Inputs (1X), addresses 16 times assigned data

areas (Data Allocation Type) are allotted with the Data Allocation

Type ‘1’ and ‘4.’ With ‘8’ and ‘16,’ 64 (4 × 16) are automatically al-

lotted.

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.)

0

15

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.
