Ethernet Channel Characteristics

Original instructions

Overview

The Ethernet modules have a standard interface for connecting to a 10/100BASE-T network and on the front panel there is a RJ45 connector for a pin-to-pin link via a link cable comprising two independent twisted pairs.

Functions supported by the modules include:

Support	Service	Protocol	Functions
TCP-IP Services	Messaging	UNI-TE	Client/server mode Synchronous requests of 256 bytes Asynchronous requests of 1 Kbyte
	Messaging	Modbus	Data exchange
	I/O Scanner	Modbus	Access to inputs/outputs
	Network management	SNMP	Agent SNMP, MIB II, MIB Schneider
	Web	HTTP	Preset, non-modifiable website on TSX ETY 4103/PORT Website which can be modified and increased by increments within the limit of 7.5 Mb on TSX ETY 5103
	Management of IP addresses	BOOTP/DHCP	Client and address server
	Global Data	UDP	Exchange of data between stations
	Electronic Mail Notification Service	SMTP	Reports alarms or events using emails Define and update text and variable information
	Time synchronization service	NTP	Synchronizes clocks over Internet to referenced time source Event recording Event synchronization Alarm and I/O synchronization

Transmission Control Protocol/Internet Protocol. TCP/IP is the communication protocol of the Internet.

simple network management protocol. The UDP/IP standard protocol used to monitor and manage devices on an IP network.

HyperText Transfer Protocol. HTTP is the protocol for the formatting and transmission of files on the world wide web. HTTP runs on top of TCP/IP (Internet) protocols.

bootstrap protocol. A UDP/IP protocol that allows an Internet node to obtain its IP parameters based on its MAC address.

dynamic host configuration protocol. DHCP is a TCP/IP protocol that allows network devices (DHCP clients) to obtain their IP addresses from a DHCP server through a request to the server.

Global Data provides the automatic exchange of data variables for the coordination of PLC applications.

Simple Mail Transfer Protocol. SMTP is a transmission protocol for sending and receiving e-mail. SMTP messages are usually retrieved from a server with an e-mail client (such as POP or IMAP).

network time protocol. NTP synchronizes the time of one client or server to the time of another server or referenced source (such as a satellite receiver).
