MODBUS I/O ASSIGNMENT

The DIP SW located at the front of the module switches the unit’s data allocation mode.

In the Data Allocation Mode 1, one (1) word is assigned per module. The second channel of analog I/O modules cannot be used.

When I/O module of 32-bit data is used, set the Data Allocation Mode to 2.

In the Data Allocation Mode 2, two (2) words are assigned per module regardless of whether the second word area is required

or not.

For discrete I/O, 16-channel area is automatically assigned to each module. With a 4-channel module, the bits assigned to ch. 5

through 16 remain “0.”

A 4-point analog I/O module takes two addresses per module. For example with the model R8-SV4N located at the module

address 5, the inputs 1 and 2 are assigned to the address 5, and the inputs 3 and 4 are to the address 6. Do not assign another

module to the address 6. All 4 inputs (input 1 through 4) can be used with Data Allocation Mode 2, while only the inputs 1 and 3

can be used with Data Allocation Mode 1. R8-NM1 Version 1.04 or later can deal with I/O mixed modules. The version of R8-NM1

is confirmed with configurator software (model: R8CFG).

Note: DO NOT access addresses other than mentioned below. Such access may cause problems such as inadequate operation.

PULSE DATA (16-bit data)

16-bit binary data is used for pulse data (16-bit data).

Negative value is not available, the data is shown with the range 0 to 65535.

15

0

■ PULSE DATA (32-bit data)

32-bit binary data is used for pulse data (32-bit data).

Lower 16 bits are allocated from the lowest address to higher ones, higher 16 bits in turn.

32-bit data cannot be accessed using floating addresses.

0

16-bit binary data is used for temperature data.

With °C, K 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.

■

ANALOG DATA (CT DATA)

16-bit binary data is used for CT data.

Conversion data is shown by the engineering unit value multiplied by 100 or 1000. For example, for 520.35A when 0 to 600 A

range, the data is 52035 as the conversion data is the engineering value multiplied by 100.

Negative value is not available, the data is shown with the range 0 to 65535.
