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 following
components:
– Field Devices
– Linking Devices
– Interface Devices
– Host Devices for Operator display
– Host Devices for Configuration
The system also needs at least one Time server
and 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.
