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.
