Ethernet (HSE) Backbone of second generation FF systems
– Takes the place of RS485 and coax solutions
– For higher level devices• Linking device• Controller• Gateway• Remote I/O
Unique features– High speed
– “DCS style” redundancy
– FOUNDATION application layer
– FOUNDATION function block diagram programming language
FF throughout the system

Interoperability Standard backbone Eliminates many gateways Interoperability for controllers etc.
Does for us what H1 did, but at a
higher level.

Where Else Will HSE Solutions Be Seen?Software
– Process visualization– Configuration tools– OPC servers– Bus analyzers– Network management– Tightly integrated online instrument
asset management
Networking Accessories– Switches– Routers– Wireless access points– Industrial cables and connectors

Relation to OPC Software-to-Software OPC Foundation OPC server for HSE exists Permits non-HSE applications to access data
– Read/Write (DA)
– Capture (A&E)
– Link (DX)
Software gateway to other systems

HSE Benefits and Savings
“...dedicated to a single international fieldbus.”© 2003 Fieldbus Foundation
11
Ethernet Benefits High speed
– 10 Mbit/s, 100 Mbit/s, faster
– Handles more information than other media
Well understood– Plenty of books
– Lots of experienced technicians
Many media options– Copper
– Optical fiber
– Short-range wireless
– Long-range wireless
– ADSL connectivity
– Dial-up connectivity
Multi-protocol– HSE
– Others
There are more Ethernet technicians in Austin than there are Fieldbus technicians
world wide.

HSE Fieldbus: Interoperable Ethernet Ethernet and TCP/IP is not sufficient for interoperability
– Most Ethernet solutions are proprietary
HSE is the standard application layer and user application Interoperability at the controller level Integration of package units

Standardize Don’t make new investments in diverse technologies
– Standardize on one technology
– Use “foreign” buses only to connect with installed base
To enable users to have a single bus in their plant... ...Manufacturers will have to support many options for bus for their
products Some HSE device types may not appear until manufacturers
understand users are serious about it.– May need to a corporate position/strategy paper
“...dedicated to a single international fieldbus.”© 2003 Fieldbus Foundation

Tower of Babel In most systems you can mix buses Mixed buses are hard to maintain
– Media
– Topologies
– configuration tools and methodology
– Tools
– Gateways/interface cards
Cost may outweigh benefits
“...dedicated to a single international fieldbus.”© 2003 Fieldbus Foundation
29
Diminishing Returns Adding another bus may not be worthwhile Additional buses primarily support cyclic I/O
– Don’t support e.g. EDDL or FDT/DTM for Profibus parameterization
– Rely on third-party tools or proprietary pages
“...dedicated to a single international fieldbus.”© 2003 Fieldbus Foundation

Mix Weak link Loss of integration
– Don’t support status propagation
– Different data types and object structure
