7.3.1 Ethernet (server) driver
(1) Driver setting
Ethernet (server) driver stands for the protocol built-in XGT FEnet module. 2 kinds of server
protocol, XGT server and MODBUS TCP/IP, are built-in XGT FEnet I/F module. Ethernet(server)
driver can be used to communicate between Ethernet devices with XGT or MODBUS TCP/IP
protocol. The destination station in Ethernet communication system is generally MMI (or HMI),
where communication is available with the correspondent device only through parameters setting
without additional communication programming by user. [Fig. 7.3.1] shows the typical example of
communication with MMI PC with Ethernet driver used, where FEnet responds if MMI PC
requests to read or write data.

[Table 7.3.1] Types of Ethernet (server) drivers
Notes
(1) The number of drivers is changeable according to specified Ethernet channel.
Be careful! If Ethernet channel is specified, the number of drivers available will be decreased
as many as specified.
(2) Ethernet (server) driver supports 1:N communication, where accordingly, several master
devices can take data through a specified port connected with.
