Industrial Ethernet Protocols
Feb 13, 2017

Dang Ethernet for information technology Shi, application layer including HT-TP, and FTP, and SNMP, common agreement, but dang it for industrial control Shi, reflected in application layer of is real-time communications, and for system group State of object and engineering model of application agreement, to 21st century, also no unified of application layer agreement, but by widely support and has development out corresponding products of has 4 species main agreement: HSE, and Modbus TCP/IP, and ProfINet, and Ethernet/IP.


Foundation fieldbus FF released in 2000 Ethernet specifications, says HSE (High Speed Ethernet). HSE is a combination of FFIll IEEE802.3,TCP/IP Ethernet protocol protocol family. FF Fieldbus Foundation implementation-specific orientation of the HSE control network and Internet integration.

HSE is a core part of the technology links, it is HSE architecture Hl (31.25kb/s) device 100Mb/s HSE key components of backbone, but also has the function of bridges and gateways. Network bridge function can be used to connect multiple H1 segments, so that the same H1 H1 devices on the network segment between peer communication without interference of the host system;

Gateway feature allows HSE network connections to other plant control network and information network, HSE linking device H1 subsystem needs to make message explained, but packet data collection from the H1 bus segment and Hl addresses into IP addresses.
