1.1 Introduction
This user’s manual is prepared to describe Fast Ethernet Interface module of XGT series PLC
(hereinafter referred to as FEnet I/F module, 1Gbps).
Ethernet is a ‘technical standard' established by the international organization of IEEE.
Communication is controlled by CSMA/CD method and network can be established with easy. In addition,
a great amount of data can be transferred with high speed. FEnet I/F module is an interface module to
communicate data between higher level system such as host PC and PLC, or between PLCs with
electric/optical media (10BASE-T/100BASE-TX/1000BASE-T, 100BASE-FX/1000X).
[Fig. 1.1.1] Configuration diagram of FEnet system
FEnet I/F module has variety applicable communication systems. Refer to Chapter 4 System Configuration
for detailed system configuration and its description.
1) Communication between PLC and host PC (MMI)
2) Mutual exchange or monitoring data between PLCs /monitoring
3) Data management or system control for field devices.
