MODEL(Fuji Electric T-Link use)

BEFORE USE ....
Thank you for choosing us. Before use, please check contents of the package you received as outlined below.
If you have any problems or questions with the product,
please contact our sales office or representatives.
■ PACKAGE INCLUDES:
Network interface module...................................................(1)■ MODEL NO.
Confirm Model No. marking on the product to be exactly
what you ordered.
■ INSTRUCTION MANUALThis manual describes necessary points of caution whenyou use this product, including installation, connection andbasic maintenance procedures.

POINTS OF CAUTION■ HOT SWAPPABLE MODULES• The module can be replaced while the power is ON. Be
sure to replace it when the module is not communicating with a host, as it may affect the system. Replacing
multiple modules at once may greatly change line voltage
levels. We highly recommend to replace them one by one.

R3-NF1■ AND ....
• The unit is designed to function as soon as power is supplied, however, a warm up for 10 minutes is required forsatisfying complete performance described in the datasheet.

INSTALLATION
Use the Installation Base Model R3-BS, or Model R3-BSW
for free I/O address capability.
Before mounting the Network Interface Module onto theBase, make sure to configure the module as explained below.
■ DATA ALLOCATIONThe setting determines the data area size assigned to each
I/O module mounted on the base.
The data sent/received via T-Link is mapped according tothis setting.
See “COMPONENT IDENTIFICATION.”■ NODE ADDRESS
See “COMPONENT IDENTIFICATION.”■ NETWORK SLOTS ON THE BASE

■ POWER INPUT RATING & OPERATIONAL RANGE• Locate the power input rating marked on the product andconfirm its operational range as indicated below:		100 – 120V AC rating: 85 – 132V, 47 – 66 Hz, approx. 25VA		200 – 240V AC rating: 170 – 264V, 47 – 66 Hz, approx. 25VA		 24V DC rating: 24V ±10%, approx. 14W■ GENERAL PRECAUTIONS• DO NOT set the switches while the power is supplied.
The switches are used only for maintenance without thepower.
■ ENVIRONMENT• Indoor use.
• When heavy dust or metal particles are present in theair, install the unit inside proper housing with sufficientventilation.
• Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
• Environmental temperature must be within -10 to +55°C(14 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.

With Model R3-BS base, mount the I/O Modules from theleft end (I/O 1) to the right in order that the Network Module assigns data areas from I/O 1.
Network Module(s) and Power Module are mounted basically at the right end though technically they could be mounted in any position. When mounting Network Module(s) orPower Module to I/O 1 or I/O 2 etc. the I/O data area occupied with Network Module(s) and Power Module will notbe usable.
With Model R3-BSW base, there is no limitation in mounting positions as I/O address can be assigned freely to each
module using rotary switches equipped on the base.

■ WIRING• Do not install cables close to noise sources (relay drive
cable, high frequency line, etc.).
• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.

TRANSMISSION DATA DESCRIPTIONSThe DIP switches on the front of the module specify each I/O module’s I/O points and I/O type. The DIP switches on the sideof the module specify status data.
The allocation area, which is set in order from the slot No. 1, is assigned to the I/O data. I/O module’s data exceeding theconfigured area is unable.
With input status data ON, the last 2 words of the input data area are used as status data. The status data setting is available
for firmware version 1.02 or later. For other versions SW3-3 setting is ignored and the device works as if SW3-3 is off. WhenI/O data and the status area are duplicated, status data takes priority.
For example, when the total number of I/O points is of 16, 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		
1Then the I/O data are assigned as in the figures below:■ WITHOUT STATUS DATA (SW3-3: OFF)• INPUT-ONLY or OUTPUT-ONLY DATA
Data areas specified with the side DIP switches are assigned to each module from Module 1 through Module 7 inturn.
If the total number of I/O points is of 4 or 8, non-existingdata are not sent/received.

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.

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.

R3-NF1■ 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 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.
