Unmodified Ethernet for Industrial Automation?

• Benefits of Ethernet for Automation

• Ethernet Features – an Overview

• Limiting Factors of Ethernet as Fieldbus Replacement

Fieldbus Foundation

High Speed Ethernet (HSE):

What are the benefits of HSE?

….Use of unmodified Ethernet and

standard IP makes HSE systems more

cost-effective than other Ethernet

solutions and proprietary networks….

SUE:

Standard

Unmodified

Ethernet

Benefits of Ethernet for Automation

• Ethernet is in use for Controller/Controller communication since many

years, as it saves money to use commodity technologies:

Examples:

• CAN (originally developed for automotive applications)

• PC-based Controls

• Windows + Linux

• So Automation benefits from the much larger IT Communication

• Thus low cost hard- and software

• If also on Fieldbus ( I/O, Sensor and Drives) Level: just one

communication technology remaining

•

Improvement also financed (and driven !) by others

Ethernet Overview: CSMA/CD, TCP/IP & others

• Architecture

• Physical Layer: Signal, Cables + Wiring

• Media Access Control

• Name Resolution

• Routing

• IP, TCP + UDP

This diagram was hand drawn by Robert M. Metcalfe and photographed by

Dave R. Boggs in 1976 to produce a 35mm slide used to present Ethernet

to the National Computer Conference in June of that year.

Ethernet Definition (Wikipedia)

Ethernet is a frame-based computer networking

technology for local area networks (LANs).

It defines wiring and signaling for the physical

layer, and frame formats and protocols for the

media access control (MAC)/data link layer and

a common addressing format

Ethernet is standardized as IEEE 802.3.

It has become the most widespread LAN

technology in use during the 1990s to the present,

and has largely replaced all other LAN standards

such as token ring, FDDI, and ARCNET.

http://standards.ieee.org/about/get/802/802.3.html

7 Application Layer

contains a variety of commonly used protocols, such as file

transfer, virtual terminal, and email

5 Application Layer:

HTTP, FTP, rlogin, Telnet, DHCP,...

6 Presentation Layer

manages the syntax and semantics of the information

transmitted between two computers

5 Session Layer

establishes and manages sessions, conversions, or dialogues

between two computers

4 Transport Layer

splits data from the session layer into smaller packets for

delivery on the network layer and ensures that the packets arrive

correctly at the other end

4 Transport Layer: TCP + UDP

Handles communication among programs on a network.

3 Network Layer

controls the operation of a packet transmitted from one network

to another, such as how to route a packet.

3 Network Layer: IP (Internet Protocol),

This layer is used for basic communication, addressing and routing.

2 Data Link Layer

transforms a stream of raw bits (0s and 1s) from the physical

layer into an error-free data frame (packets) for the network layer

1/2 Medium Access Control (MAC)

IEEE 802.3: CSMA/CD (Ethernet), 802.4 Token Bus (ARCnet), 802.5 Token

Ring, 802.11 Wireless,

1 Physical Layer

transmits signals across a communication medium

Cables, cards and physical aspects: ISO/IEC 11801,

parts also in IEEE 802.3

ISO/OSI - Model TCP/IP - Model

ISO/OSI, IEEE 802 and TCP/IP
