[Abstract]:PROFIBUS-DP is an international field bus for process automation and factory automation. It is an open digital communication system with a wide range of applications and is suitable for high reliability requirements. The communication protocol .Modbus, which is fast and time demanding, is a kind of communication protocol originally applied in the field of electronic controller. Through MODBUS protocol, different controllers can be realized. And the controller communicates through the network (such as Internet) and other devices. At present, there are many kinds of products related to PROFIBUS-DP and MODBUS bus, including related slave station equipment (such as digital sensor, transmitter, etc.). Instruments and actuators are the key technologies of current research. But there are few researches on multi-protocol integration at home and abroad, so this paper studies and designs a kind of PROFIBUS-DP and MODBUS integrated slave node device. The fast switching between the two slave nodes is realized. The main contents are as follows:. 1. Firstly, this paper introduces the basic development situation of two fieldbus at home and abroad, and the research content and significance of this subject, then analyzes the architecture, communication principle and data format of PROFIBUS-DP and MODBUS. 2. Based on the analysis of two common fieldbus technologies, the integration of two slave nodes on a single microprocessor is studied and realized, and the problem of functional switching between two slave nodes is solved. At the same time, the overall design scheme of the integrated slave module is given. On the basis of this, the concrete solution of hardware and software is expounded. In hardware design, the functions of PROFIBUS-DP slave node based on MCU SPC3 protocol chip and RS485 driver circuit and MODBUS slave node function with MCU and RS485 drive circuit as the core are realized. Finally, the working principle of the hardware circuit is explained. In the software design, the slave node function codes of two kinds of fieldbus are compiled by using C51 language, and on this basis, it is merged into an integrated slave node code. 3. According to the functions and technical requirements of PROFIBUS-DP and MODBUS slave station test, the test scheme of this module is analyzed and demonstrated in detail. The experimental results are analyzed, and it is proved that the proposed scheme of PROFIBUS-DP and MODBUS integrated slave module is correct and feasible.
