局部变量在叠片系统PLC模块化设计中的应用

Application of Local Variable in Sheet Stacker PLC Modular Programming System

通过局部变量的运用,将叠片系统工艺流程中相似的功能抽象提取,提炼出相同的部分,定义不同的部分,实现程序模块化设计。从而使程序设计简单和直观,增强易读性和可维护性,大幅度减少编程序辑量,缩短编程时间,提高设计效率,使叠片系统的设计趋向简洁化和高效化。

This paper introduces the realization of PLC modular programming,through the use of local variables,and the same parts are extracted of the technical process while the different parts are defined.It successfully improves the programming efficiency,and the design of the modular programming system tends to be concise and efficient.
