Confirm Model No. marking on the product to be exactly
what you ordered.
■ INSTRUCTION MANUALThis manual describes necessary points of caution when
you use this product, including installation, connection andbasic maintenance procedures.

POINTS OF CAUTION■ CONFORMITY WITH EU DIRECTIVES• The equipment must be mounted inside the instrument
panel of a metal enclosure.
• The actual installation environments such as panel configurations, connected devices, connected wires, may affectthe protection level of this unit when it is integrated ina panel system. The user may have to review the CE requirements in regard to the whole system and employ additional protective measures to ensure the CE conformity.
■ 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.
■ GENERAL PRECAUTIONS• DO NOT set the switches on the module while the poweris supplied. The switches are used only for maintenancewithout the power.
■ 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 continuousvibration. 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 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.

R3-GC1■ 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, be sure to configure the module as explained below.
■ CC-Link VERSION & EXPANDED CYCLIC
Set CC-Link’s version and expanded cyclic by using the side
DIP switch SW3.
The setting determines the number of slots which the module is assigned to.
See “TRANSMISSION DATA DESCRIPTIONS”.
■ STATION NO. & BAUD RATE
See “COMPONENT IDENTIFICATION”.
■ NETWORK SLOTS ON THE BASE
I/O 1

I/O 2

I/O n

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.
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.
R3-GC1 occupies up to 16 slots. Be careful not to use theslot numbers occupied by this unit for real I/O modules to bemounted on the same base. Also, when mounting this unit,
be careful about the slot position and the number of slots
to be occupied so that any of the slot numbers will not begreater than 16. The Network module cannot read data for
an I/O module assigned to slot No. 17 or later.

R3-GC1TRANSMISSION DATA DESCRIPTIONS
Use the DIP SW located at the side of the module to specify expanded cyclic setting. 16 words input and 16 words output
make 1 cyclic. Max. 8 cyclic (128 words input, 128 words output) transmission is available. 1 cyclic is equivalent to 1 I/Omodule (analog input 16 points, analog output 16 points). Max. 8 I/O modules can be assigned to 8 slots.
Note: Do not mount any modules in the slots which are occupied by virtual modules. If a real I/O module is mounted in the slot, aninternal bus error occurs and the ERR LED turns on. Max. 16 real I/O modules and virtual modules are available. The interface module can not read the data for more than 16 modules.

■ WHEN R3-GC1 IS MOUNTED ON SLOT NO. 2 (4 CYCLIC)
Real I/O modules are mounted on Slots No. 1 and 2, however, the network module (R3-NE1) recognizes that each of Slots No.
1 to 5 is occupied. That is, R3-NE1 recognizes R3-SV4 mounted on Slot No.1 as it is and recognizes R3-GC1 mounted on Slot
No.2 as divided into four modules and occupying Slots No. 2 to 5.
