Foundation Fieldbus High Speed Ethernet (hse) and Tcp/ip
نویسنده
چکیده
The use of the low speed Foundation Fieldbus H1 (31.25kbits/s) has been fairly extensively documented. But an area of growing interest is that of Industrial Ethernet and now the Foundation Fieldbus HSE standard which builds on commercial off the shelf (COTS) Ethernet components. This paper examines the operation and structure of HSE with an emphasis on the lower layers (Ethernet and TCP/IP) and shows how Foundation Fieldbus takes the higher ground in the Fieldbus debate by default due to its use of Ethernet and TCP/IP which have become extremely popular. Whilst there may be a feeling that a considerable amount of this material is irrelevant to someone working with Foundation Fieldbus systems, it is the author’s belief that a good knowledge of Ethernet and TCP/IP is essential in designing, troubleshooting and fixing problems with HSE based networks.

Fieldbus Foundation's open, integrated architecture for information integration
Fieldbus Foundation's open, integrated architecture for information integration consists of a field-level bus, a host-level network based on Ethernet, and at a higher level ties in with OPC for data server integration. These three technologies complement each other rather than compete. They have several mutually exclusive features making them suitable for different functions, together resulting...

Recent technological developments are pulling fieldbus networks to support a new wide class of applications, such as industrial multimedia applications. These applications are usually supported by the widely used TCP/IP stack. It is thus essential to provide support to TCP/IP based applications, in fieldbus networks. This paper presents an effort that is being carried out to integrate the TCP/I...
متن کاملPerformance Optimizations for High-Speed TCP on BCL-4
This paper presents experiences with TCP/IP optimizations on BCL-4 – a high-performance low-level communication protocol used on a cluster of SMPs called DAWNING-4000. We presently implement the TCP/IP support on BCL-4 with a gigabit-per-second Myrinet network. This implementation (called BCL-4/IP) realizes most of optimizations for TCP/IP, including extended MTU, scatter/gather DMA, checksum o...
