Example Embodiment

[0019] figure 1 It is a protocol conversion adapter composed of a third-generation protocol chip and a microprocessor. It is mainly composed of a microcontroller unit MCU, a third-generation protocol chip, and other auxiliary components such as power supply and clock. The communication quantity of the adapter is only 8KB, which cannot meet the working needs of the adapter. Requirements for larger traffic occasions. The general solution to this technical problem is to use a shift register or a serial register chip SRE to expand the communication volume of the protocol chip, but it will increase the cost and the circuit design is also more complicated due to the increase of the serial register chip SRE, which increases the failure points and reduces the adapter. Reliability at work.

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...
