Abstract


The fieldbus technology have digitized, fully distributed, openness and interoperability features of today's hottest automation technology. PROFIBUS fieldbus is one of the most widely used fieldbus, its application areas including manufacturing automation, process industry automation, building automation, transportation and electric power. In recent years, domestic enterprises have launched PROFIBUS PA product development. The PA products through authorized laboratory must allow the listing of sales and use their protocol compliance (consistency) test. Currently, the authorized laboratory testing only for forming the PA product, not commercial testing tools for PA products on the domestic and foreign markets, businesses can not be in the early stages of product development and debugging of test. If you molded PA product does not pass the test, you must return to the factory to modify, or even from the new design, development, greatly increasing the difficulty and development cycle of enterprise development. This article in the in-depth study on the basis of the fieldbus protocol test PROFIBUS PA product testing and R \u0026 D PROFIBUS DP communication protocol and PA line regulation test software and hardware platform. The main content of the paper include the following aspects: 1. PROFIBUS fieldbus technology understanding, on the basis of the analysis protocol test theory proposed based Ethernet PROFIBUS PA test program, including the basic framework and test process, which The innovation of this paper. Developed PROFIBUS PA test system based on Ethernet, the system mainly for PA equipment conformance testing. The development of the test system is carried out in accordance with the entire development cycle of software engineering. In the requirements analysis phase, indicating the need for the development of the system, press software partitioning describes the functional requirements of the whole system; further functional partitioning, respectively, on the part of the test system software modules in the design phase, and give a the module functional schematic; implementation phase, to build the ARM chip as the core hardware platform, software implementation part focuses on the design ideas and implementation process of testing software modules, given the flow chart of the various modules of the software code and operating results. 3 on the test system for authentication. Through the application of the system to a real test case, and the test results and test laboratory authorized software test results to compare test results illustrate the correctness of the system.
