High Speed Ethernet
The seamless connection of Fieldbus H1 to High Speed Ethernet has been addressed by the Fieldbus Foundation
The Fieldbus User and application layer requirements are incorporated in the High Speed Ethernet specification.

Why Ethernet?
•Bandwidth (10 Mb/s or 100 Mb/s)
•Broad commercial availability of
interfaces and components
•Seamless connection with upper networks
in the plant and with complex devices
•Enables use of thin clients
•Use of Web technology.

What is High Speed Ethernet (HSE)?
– It is the Fieldbus Foundation framework for interconnecting field devices to each other and to hosts using standard Information Technology (IT).
–Devices and hosts can be located anywhere on a TCP/IP network.
– Integration into a control system will depend on system awareness of FF function block/architecture

HSE system components
A representative HSE system has the followingcomponents:
– Field Devices
– Linking Devices
– Interface Devices
– Host Devices for Operator display
– Host Devices for Configuration
The system also needs at least one Time serverand a DHCP Server.

Engineering a HSE Installation
Ethernet provides a common method of
connecting to a HSE network.
•Control segments may be constructed
from HSE devices and standard
switch/hub technology.
•Any type of Ethernet (wire, fiber,
radio) can be used, as long as it can be
connected to a standard speed-sensing
switch.

What To Look For in Purchasing HSE
Device Class 41-45 Specify Functionality(s) i.e. Field Device, Linking Device, Interface or Host Device. All HSE Devices must qualify as one or more of these classes.
Device Classes 46-49 Specifies Device Networking Capability e.g. redundancy, time handling, IP address handling. All HSE Devices must be characterized by these classes.
