Appendix 5 Ethernet App5-19
[Send Timeout]
Set the time-out time for the V7 series to send a EREAD/EWRITE command on the Ethernet.
[Port No.] (256 to 65535) (Default: 10000)
Set the port number.
The port number may be fixed depending on the PLC model. Refer to the instruction manual for
the PLC.
Example: MITSUBISHI QnA series 5000 Default
(changeable by sequence)
QnH(Q) series link (with auto-open UDP port):
5000 Default
(changeable by sequence)

LG MASTER-K series 2005 Fixed
GLOFA GM series 2005 Fixed
MODBUS TCP/IP 502 Fixed
KEYENCE KV700 8501 Default
(changeable by sequence)
Automationdirect D2-240 28784 Fixed
[Select Port]
Select either AUI or 10BASE-T. When connecting to the 10BASE-T connector (LAN) of V7i or
V706 + DU-01, select [10BASE-T].
Select either [10BASE-T] or [AUI] when CU-03-2 is mounted.
[Memory Protect]
Attach a check mark ( ) when write-protecting the internal memory or memory card.
[Default Gateway]
Attach a check mark ( ) when setting the default gateway.
IP Address
This is an address that is used for recognizing each node on the Ethernet and should be unique.
The IP address is 32-bit data which consists of the network address and the host address and can be classified
into A to C depending on the network size.
Notation
A string of 32-bit data is divided into four, and each segment delimited with a period is in decimal notation.
Example: The IP address in class C shown below is represented as “192.128.1.50.”
11000000 10000000 00000001 00110010
Port No.
Multiple applications are running on each node, and communications are carried out for each application
between the nodes. Consequently, it is necessary to have a means to identify the application that data should
be transferred to. The port number works as this identifier.
Each port number is 16-bit data (from 0 to 65535). However, since some numbers are already used, the
setting range available with V7i or V706 is from 256 to 65535. It is recommended to set a greater number.
Note that “8001” is allocated to the port for screen data transfer from the editor. Use a number other than
“8001.”
Default Gateway
A gateway and a router are used for communicating between different networks.
The IP address of the gateway (router) should be set to communicate with the node(s) on other network.
