FF HSE Fieldbus Overview

FF HSE fieldbus In 1998, the US FIELDBUS FOUNDATION (FF) foundation decided to develop H2 on-site bus using high speed Ethernet, HSE technology, as a backbone network of communication networks above the fieldbus control system, which consists of H1 fieldbus integration The information integrated is open architecture, which gives a system structure. The HSE network follows the standard Ethernet specification and applies some functions as appropriate according to process control, but these additional functions can be seamlessly operated in the standard Ethernet structure framework, so the FF HSE bus can use the current popular commercial use. (COTS) Ethernet equipment. The 100Mbps Ethernet topology is to form a star connection using a switch, which has a firewall function to block special types of information access network. HSE uses standard IEEE802.3 signal transmission, standard Ethernet wiring and communication media. The distance between the equipment and the switch is 100 meters, and the cable can reach 2 kilometers. HSE uses the connection device (LD) to connect the H1 subsystem, the LD performs a bridge function, which allows the field devices on the H1 network to complete the point-to-point peer-to-peer communication. HSE supports redundant communication, any device on the network can be redundantly configured. system structure The 1 to 4 layers of FF HSE are defined by the existing Ethernet, TCP / IP and IEEE standards, HSE and H1 use the same user layer, fieldbus information specification (FMS) define service interfaces in H1, field device access Agent (FDA) provides an interface for HSE. The user layer specifies the functional module, the device description (DD), function file (CF), and system management (SM). FF specification 21 functional modules for basic and advanced process control use. FF also specifies a new flexible functional module (FFB) for complex batch and hybrid control applications, FFB supports data acquisition, subsystem interface, event order, multi-channel data acquisition, PLC, and other protocol communication. Network connector. Technology area Realize the allocation reading and writing release function of Linux system memory The CAN bus has become a bus standard for the electric system.
