INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic 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 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.
■
POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
100 – 240V AC rating: 85 – 264V, 47 – 66 Hz
approx. 20VA at 100V AC
approx. 28VA at 200V AC
approx. 30VA at 240V AC
24V DC rating: 24V ±10%, approx. 12W
■
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 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.
■
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 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 Modbus is mapped according to
this setting.
See “COMPONENT IDENTIFICATION” and “MODBUS
I/O ASSIGNMENTS”.
■
NODE ADDRESS & BAUD RATE, ETC.
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 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.
