Notes on Ethernet Communications
For V7i:
•
To use Ethernet communications on V7i, use the 10BASE-T connector (LAN) provided on the unit.
It is not possible to use Ethernet or FL-net (OPCN-2) communications by attaching the
communication I/F unit CU-03-2 to V7i at the same time.
When CU-03-2 is mounted, the 10BASE-T connector (LAN) provided on the unit cannot be used.
•
When using Ethernet communications with CU-03-2 mounted, the Web server or e-mail function
cannot be used.
For V7:
•
To use Ethernet communications on V7, the communication interface unit “CU-03-2” must be
mounted.
In this case, however, the Web server or e-mail function is not available.
For V706:
•
To use Ethernet communications with the V706, an optional unit, DU-01, is necessary.
Web server and e-mail functions are available.
IP Address for the V7 Series
To enable Ethernet communications on the V7 series, it is necessary to set the IP address for
identification of the V7 series on the network.
For details on IP address setting, refer to the separate V-SFT Additional Specifications for the V7
series and V706 Hardware Specifications for V706.
