2.9.4 Network Modules for ETHERNET
ETHERNET is the most widespread network for connection of information processors such as
personal computers and work stations. By loading an ETHERNET interface into the PLC, pro
-
duction-related management information can be transmitted rapidly to personal computers or
work stations. ETHERNET is a platform for a very wide range of data communications protocols.
The combination of ETHERNET and the extremely widespread TCP/IP protocol enables
high-speed data communications between process supervision systems and the MELSEC PLC
series. TCP/IP provides logical point-to-point links between two ETHERNET stations.
The programming software GX IEC Developer provides function blocks or setup routines for the
PLCs, making the configuration of one or more TCP/IP links a quick and easy process.

FX3U-ENET
The FX3U-ENET communications module provides the
FX
3G,FX3U or FX3UC with a direct connection to an
Ethernet network.
The FX
3U-ENET enables 8 ports of simultaneous
Ethernet communication with features such as peer-to-
peer communication, extensive e-mail send/receive
options, and program upload/download. The FX
3U-ENET
is also used to communicate with GOTs via the Ethernet.
