INSTRUCTION MANUAL
ETHERNET INTERFACE MODULE
(Modbus/TCP) MODEL R3-GE1
BEFORE USE ....
Thank you for choosing M-System. 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 M-System’s 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 MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic 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 con-
figurations, connected devices, connected wires, may af-
fect the protection level of this unit when it is integrated
in a 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 conform-
ity.
■HOT SWAPPABLE MODULES
• The module can be replaced while the power is ON. Be
sure to replace it when the module is not communicat-
ing 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 power
is supplied. The switches are used only for maintenance
without the power.
■ENVIRONMENT
• Indoor use.
• When heavy dust or metal particles are present in the
air, install the unit inside proper housing with sufficient
ventilation.
• Do not install the unit where it is subjected to continuous
vibration. Do not apply physical impact to the unit.
• 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.
■AND ....
• The unit is designed to function as soon as power is sup-
plied, 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-BS, or Model: R3-BSW
for free I/O address capability.
Before mounting the Network Interface Module R3-GE1
onto the base, be sure to configure the module as explained
below.
■MODULE ALLOCATION
Use the side DIP SW1 to set the number of slots which the
module is assigned to.
See “TRANSMISSION DATA DESCRIPTIONS.”
■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 the
left end (I/O 1) to the right in order that the Network Mod-
ule assigns data areas from I/O 1.
Network Module(s) and Power Module are mounted basi-
cally at the right end though technically they could be
mounted in any position.
With Model R3-BSW 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.
R3-GE1 occupies up to 16 slots. Be careful not to use the
slot numbers occupied by this unit for real I/O modules to be
mounted 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 be
greater than 16. The Network module cannot read data for
an I/O module assigned to slot No. 17 or later.

CHECKING ETHERNET CONNECTION
■IP ADDRESS
The R3-GE1 does not support BootP Table Software. The IP Address and Subnet Mask can be configured by using the R3CON
Configurator Software.
The Modbus/TCP Port No. is fixed to 502.
■DATA ALLOCATION
Set data allocation by using the side DIP SW1. This setting specifies that how many slots the module is assigned to. Based
on the setting, the data areas are allocated to the related slots.
■WIRING
Connect an Ethernet cable to the front RJ-45 jack.
■CHECK LED
When wiring is correct, LINK and LINK10, or LINK and LINK100 are turned on.
When the module is receiving or sending data, LINK10 or LINK100 blinks.*
* ON for firmware version V1.00 or later
■CHECK R3-GE1 CONNECTION
Enter “ping” command on the Windows MS-DOS prompt as follows:
C:¥WINDOWS>ping ***.***.***.***
(***.***.***.***: Enter IP address in decimal.)
ping ***.***.***.*** with 32 bytes of data:
Reply from ***.***.***.*** : bytes=32 time<10ms TTL=64
Reply from ***.***.***.*** : bytes=32 time<10ms TTL=64
Reply from ***.***.***.*** : bytes=32 time<10ms TTL=64
Reply from ***.***.***.*** : bytes=32 time<10ms TTL=64
Ping statistics for ***.***.***.***
Packets:Sent=4,Received=4,Lost=0(0% loss)
When the connection is normal, the replies are as shown above. When the connection fails due to a problem such as a wrong
IP address, the reply will be something else, e.g. “time over.”
■CHECK CONNECTION TO THE APPLICATION SOFTWARE
Check Point 1: LINK LEDs
When a normal connection is established, the front LINK and LINK10 or LINK100 are turned on regardless of data sending/
receiving status. Check power supply to the hub in case that these LEDs are not on.
Check Point 2: RUN Indicator LED
When the side DIP SW3-4 is set to OFF, the RUN Indicator LED turns to Green if R3-GE1 and R3 communication interface
module send/receive data in normal.
Check Point 3: Sending/Receiving Indicators
When the side DIP SW3-4 is set to ON, the RUN Indicator LED turns to Red in data receiving, and the ERR Indicator LED
turns to Red in data sending. In normal operating conditions, these LEDs may seem to blink at once due to the high speed
transmission.

Note: DO NOT access addresses other than the ones mentioned above. Such access may cause problems such as malfunction.
• Module Status
Module Status indicates whether individual I/O module is mounted or not. The bit corresponding to the mounted slot turns
to “1,” and the unmounted slot to “0.”

TRANSMISSION DATA DESCRIPTIONS
Use the DIP SW located at the side of the module to specify module allocation.
1 module is equivalent to 1 I/O module with 16 words analog input and 16 words analog output. Max. 8 modules (128 words
input, 128 words output) transmission is available. R3-GE1 seems as if max. 8 I/O modules are mounted to 8 slots via Mod-
bus/TCP.
The input of the module is processed as follows.
Modbus Communication R3-GE1 Module R3 Base R3 Communication Module
In responding to the input, the output (Holding Register) command becomes valid via Modbus/TCP communication, and the
input (Input Register) command is valid in the output.
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, an
internal 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-GE1 IS MOUNTED ON SLOT NO. 2 (4 modules)
Real I/O modules are mounted on Slots No. 1 and 2, however, the network module (R3-NC3) recognizes that each of Slots No.
1 to 5 is occupied. That is, R3-NC3 recognizes R3-SV4 mounted on Slot No.1 as it is and recognizes R3-GE1 mounted on Slot
No.2 as divided into four modules and occupying Slots No. 2 to 5.
