摘　　要：随着企业对工业自动化程度要求的提高,DCS(集散控制系统)以其高可靠性、配置灵活,在工业控制系统中得到越来越广泛的应用,而性能可靠、功能完善的计算机和PLC(可编程逻辑控制器)通信接口软件技术是构成DCS的关键。文中以FX系列PLC为例,通过应用实例,介绍计算机与PLC之间通信接口软件设计、实现和利用V isual Basic程序设计语言实现这一技术的具体过程。With the increase of demand of industrial automation in companies, distributed control system is applied more and more abroad in industrial control system due to the high dependability and the flexibility of the layout, but the keystone that makes up DCS control system is the interface software of programmable controller and computer whth reliable performance and comprehensive functions. In this paper, taking FX PLC as an example, a detailed description of the design of communication interface software in computer and PLC is presented. Moreover, this paper introduces the procedure to realize this design by advanced programming language-Visual Basic. Practical application proves that the design has excellent performance, is easy to use etc..
