Rating 200 – 240V AC: 170 – 264V, 47 – 66 Hz, approx. 20VA
Rating 24V DC: 24V ±10%, approx. 12W
■ UNPLUGGING THE UNIT
Before you remove the unit from its base or mount it, turn off
the power supply for safety.
■ ENVIRONMENT
• Indoor use
• When heavy dust or metal particles are present in the air,
install the unit inside proper housing with sufficient ventila-
tion.
• 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.
■ WIRING
• Do not install cables (power supply, input and output) 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.

CC-Link INTERFACE MODULE
(CC-Link Ver.2)
■ AND ....
The unit is designed to function as soon as power is supplied,
however, a warm up for 10 minutes is required for satisfying
complete performance described in the data sheet.
INSTALLATION
Use the Installation Base Model R3-BSx, or Model R3-BSWx
for free I/O address capability.
Before mounting the Network Interface Module onto the
Base, be sure to configure the module as explained below.
■ DATA ALLOCATION
The setting determines the data area size assigned to each I/
O module mounted on the base.
The data sent/received via CC-Link is mapped according to
this setting.
See "DATA DESCRIPTION" in Page 4.
■ NODE ADDRESS & BAUD RATE
See "COMPONENT IDENTIFICATION" in Page 2.
■ NETWORK SLOTS ON THE BASE
With Model R3-BSx base, mount the I/O Modules from the
left 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.
With Model R3-BSWx base, there is no limitation in mount-
ing positions as I/O address can be assigned freely to each
module using rotary switches equipped on the base.

TRANSMISSION DATA DESCRIPTIONS
The 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 figures below:
■OUTPUT DATA
The figure below shows the allocation of the data sent from
the network module to the master.
■INPUT DATA
The figure below shows the allocation of the data sent from
the master to the network module.
[16*m] (m = cyclic expansion setting) data areas are available to the R3-NC3. Total data areas occupied by I/O modules must
be within this limitation.

•Module Status
RX(n+0)0 through RX(n+0)F indicate whether individual I/O module are mounted or not. The bit corresponding to the mounted
slots turns to "1," and the unmounted slots to "0."
•Error Status
RX(n+1)0 through Rx(n+1)F indicate error status for each module as described below. The bit corresponding to such modules
turns to "1."
R3-TSx, R3-RSx, R3-US4: Input burnout
R3-DA16A: Power input in error or disconnected
R3-YSx: Output current error (e.g. load unconnected)
•Data Error Status
RX(n+2)0 through Rx(n+2)F indicate overrange (R3-US4: out of -10% to +110%; the other types: out of -15% to +115%) status
for each module. The bit corresponding to such modules turns to "1."
•RX(n+3) through RX(n+m*7–2) are unused.
•RX(n+m*7–1)0 through RX(n+m*7–1)7 are reserved for future use. RX(n+m*7–1)B is assigned to Ready signal, which is
turned to "1" when the network module is in normal conditions. RX(n+m*7–1)8 through RX(n+m*7–1)A, RX(n+m*7–1)C
through RX(n+m*7–1)F are not used.

I/O DATA DESCRIPTIONS
■MODULE STATUS, ERROR STATUS, DATA ERROR STATUS
Shows each module's availability and error status.
■ANALOG DATA (models: R3-SV4,YV4, DS4,YS4 and US4)
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.
■TEMPERATURE DATA (models: R3-RS4,TS4 and US4)
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.
■16-POINT DISCRETE DATA (models: R3-DA16 and DC16)
■OPERATION IN CASE OF A COMMUNICATION ERRORWITH I/O MODULES
When the communication between the network module and the I/O modules is lost due to an error in an input module, the last
process values are held until the communication is re-established.

■PLC REDUNDANT SYSTEM (models: R3-NC3-x/W)
Bit 0 of RY(n+1) is assigned to designate control system or standby system. Set this bit from the host PLC to switch from the
PLC master control system to the standby system, or vice versa. The R3 module output (slave station) is controlled according
to the bit combinations as shown in the table below. No switching is required for the R3 input modules which continuously
send out data to both ‘main’ and ‘sub’ network modules.
RY(n+1) 0 = 0 : PLC master control system
RY(n+1) 0 = 1 : PLC standby system
•Operation
1) When the PLC master control/standby system bit is undefined due to no communication, the both host PLCs function as
‘standby’ system for each of R3 ‘main’ and ‘sub’ network modules. All contact outputs are off, and analog output modules
output -115%.
2) The master PLC communicates with the R3 main network module, while the standby PLC communicates with the R3 sub
network module.
3) When a wire breakdown is detected at the R3 main network, the output signal is held for the preset time period (Timer is
programmable with the PC Configurator Software, R3CON). After the time has been elapsed, the output is switched from
the R3 main to R3 sub network. Be sure to set an appropriate output signal to the R3 sub network before the switching.
The host PLC for the R3 main network is now functioning as standby system.
4) Once the PLC control is transferred to the standby system, it is necessary to set RY(n+1) 0 = 1 to the R3 main network in
order to prevent R3 output control automatically switched to the main network when the R3 main network is restored. If
it is set to RY(n+1) 0 = 0, the R3 output will be switched to the main network even when the PLC control is in the standby
system.
5) When both R3 main and R3 sub network modules are in communication, the output can be switched without delay by
setting RY(n+1) 0 values. Be sure to set an appropriate output signal to the network module before the control is switched
to it.
