CHECKING ETHERNET CONNECTION
■ IP ADDRESS
The IP address is set with PC Configurator Software (model: R3CON). BOOTP and DHCP are also available.
■ DATA ALLOCATION
Data Allocation Type must be assigned to each I/O module position to specify how many data areas (four types) are to be oc-
cupied by each.
Two bits from SW1 and SW2 are assigned to each position on the base.
■ CHECK WIRING
Connect an Ethernet cable to the front RJ-45 jack.
■ CHECK LED
When wiring is correct, LINK is turned on.
■ CHECK R3-NEIP1 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 "time over" will be received.
■ CHECK CONNECTION TO THE APPLICATION SOFTWARE
Check Point 1: LINK LED
When a normal connection is established, the front LINK is 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: MS, NS and Ethernet indicators
When the module transmits or receives data correctly, MS, NS and TX/RX indicators turn on. Since the transfer rate is high,
TX/RX indicator seems to blink.
