摘要
本文分析了目前软PLC的发展方向和存在的不足;提出了基于实时数据库来构建软PLC运行系统的思想。并通过研究软PLC运行系统的工作方式和流程,详细讨论了软PLC与实时数据库进行数据交换的方法,最后基于此方法开发了软PLC与实时数据库的接口模块。
This paper analyzes the current development direction and the shortcomings of the Soft-PLC;and the idea was put forward that based on real-time database to build a Soft-PLC running system.Through the study of soft PLC running system and the flow of work,the method that exchanging data between Soft-PLC and real-time database was discussed in detail,finally based on this method develops the Soft-PLC with real-time database interface module.
