High Speed Ethernet
• High-Speed Ethernet (HSE)– Based on Ethernet, IP and TCP/UDP
• Four basic HSE device categories:– Linking Device (LD)– Ethernet Device (ED) – Gateway Device (GD) – Host Device (HD)

HSE Interoperability
• Host Interoperability• Subsystem interoperability
– basic control– emergency shutdown– paper quality control– advanced control– compressor, turbine control– etc.

HSE Not The End of H1
• H1 used for field instruments• HSE used at the host-level• H1 and HSE complement each other

Compelling Reason to Use HSE
• Only HSE has full network redundancy• Only HSE has device redundancy• Only HSE has a programming language• Built on standard Ethernet• Networking hardware are extremely low cost
compared to the proprietary.• Wealth of options for media available including
twisted pair, fiber optics and wireless.• Commercial and industrial grades from many
suppliers.

Conclusion
• Use HSE to benefit fully from H1.• HSE simplifies the system architecture.• HSE makes Ethernet open.• HSE makes controllers interoperable.• Device and network redundancy is
required at the host-level.• HSE provides interoperable network and
device redundancy at the host level
