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
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

System Integration
Technician’s dream: •Single tool
Integrated System
•Single interface
•Single wire rules
•Homogenous
•Distributed

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.

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

Diminishing Returns
 Adding another bus may not be worthwhile
 Additional buses primarily support cyclic I/O
–
–
29
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.”

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