Communication protocol conversion adapter realized through microprocessor and protocol chip

Abstract

A communication protocol conversion adapter realized through a microprocessor and a protocol chip comprises a micro-control unit and the protocol chip which are mutually connected, wherein the protocol chip is the fourth generation IBSSUPI 4 which has greatly lowered cost and improved working reliability compared with a third generation protocol chip.

Description

technical field [0001] The invention relates to an adapter, in particular to an adapter for communication protocol conversion realized by a microprocessor and a protocol chip. Background technique [0002] The conversion adapter is an INTERBUS remote slave device, and its main function is to convert other communication protocols into INTERBUS protocols. The conversion adapter commonly used in the market to realize remote bus slave equipment is mainly composed of microcontroller unit MCU, third-generation protocol chip and other auxiliary components such as power supply and clock. The communication data volume of this adapter is only 8KB. [0003] When the conversion adapter needs a large amount of communication data, a shift register or a serial register chip SRE is generally used to expand the communication amount of the protocol chip, but this will increase the cost and the circuit design will be complicated due to the increase of the serial register chip SRE...

AI Technical Summary

Problems solved by technology

[0004] The protocol chip of the conversion adapter of the present invention adopts the fourth-generation protocol chip SUPI4, which solves the problem of limited communication data volume of the conversion adapter, greatly reduces the production cost under the premise of realizing the same function, optimizes the design of the circuit, and improves the efficiency of the conversion adapter. stability at work
