7.2.2 Type of P2P Service
(1) XGT Client
XGT Client service is used to communicate between XGT FEnet I/F modules. Through its own
protocol built-in without additionally defined frame, the user can specify communication settings
simply with basic settings of channel, data type (BIT, BYTE, WORD, etc.) and memory area. Use
port No.2004 for TCP, and port No.2005 for UDP protocol.
(2) User defined frame
This service is used to communicate between XGT FEnet I/F module and other company’s
Ethernet devices. Since the communication protocol of devices based on Ethernet is differently
defined by different makers, all kinds of communication drivers can not be provided for
respective device. Thus, the user is allowed to edit appropriately to the characteristics of the
applicable communication module, for which the user needs to specify User Defined Frame and
then define the Ethernet user’s frames with basic structure composed of Header, Body and Tail.
Up to 16 channels can be specified.
(3) Modbus TCP Client
XGT FEnet supports Modbus protocol widely used as of now as well as User Defined protocol.
