Abstract

The present invention relates to the technical field of the Foundation Fieldbus, and discloses a Foundation Fieldbus gateway, comprising: a media connection unit connected in sequence, an encoding / decoding conversion unit, a CPU, and two mutually thermally redundant modules connected to the CPU. The backup media access control unit; the media connection unit has an FF H1 interface; the media access control unit has an adaptive rate HSE interface. The invention can effectively improve the performance of the gateway and the reliability of data transmission.

Description

technical field [0001] The present invention relates to the technical field of foundation fieldbus, more specifically, relates to a foundation fieldbus gateway. Background technique [0002] Fieldbus is a communication link used in the production site to realize two-way, serial, multi-node digital communication between computerized measurement and control equipment. Foundation Fieldbus (FF, FoundationFieldbus) is the name of a fieldbus protocol developed and promoted by the Fieldbus Foundation, which complies with the open international standard IEC-61158-2. FOUNDATION Fieldbus is an all-digital, two-way transmission, multi-point communication, bus-powered communication link for connecting smart devices and automation systems. It consists of three parts: physical layer, communication "stack", user program . There are two types of Foundation Fieldbus network structures: FF H1 and FF HSE. in: [0003] FF H1 is a low-speed bus specially used for process automation, with a c...
