■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.
■POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
24V DC rating: 24V ±10%, approx. 97mA
■GENERAL PRECAUTIONS
• Before you remove the unit or mount it, turn off the power
supply and input signal for safety.
• Before you remove the terminal block or mount it, make
sure to turn off the power supply and input signal for
safety.
• 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.
• Be sure to close the terminal cover for safety.
■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.

CHECKING ETHERNET CONNECTION
■IP ADDRESS
The R7E does not support BootP Table Software. The IP Address and Subnet Mask can be configured using the R7CON
Configurator Software.
The Modbus/TCP Port No. is fixed at 502.
■CHECK WIRING
Connect an Ethernet cable to the RJ-45 connector.
■CHECK LED
When wiring is correct, LINK is turned on. When the module is connected in 100 Mbps, LINK100 is blinking.
■CHECK R7E CONNECTION
Enter “ping command” on the Windows MS-DOS 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)
Replies in case of normal connection are as shown above. If the connection cannot be established normally due to e.g. wrong
IP address, other replies such as ‘timeout’ will be received.
■CHECK CONNECTION TO THE APPLICATION SOFTWARE
Check Point 1: LINK LEDs
When normal connection with PC, PLC or hub is established, the front LINK and LINK100 (when connected in 100 Mbps)
is/are turned on regardless of data sending/receiving status. Check power supply to the switch/hub in case that these LEDs
are not on.
Check Point 2: RUN Indicator LED
A green LED turns on at the RUN Indicator LED in normal data sending/receiving with an application.
