摘要
介绍了软PLC系统iComacPLC1.0的体系结构及其基于PLC虚拟机的执行机制,并着重分析了虚拟机中元件库模块的功能和开发过程。该模块提供了梯形图编程元素的相关信息,由于符合IEC61131-3标准,并且采用面向对象的编程方法进行设计,具有通用性强、易于扩充等优点,提高了整个软PLC系统的柔性。
The structure and the implement mechanism based on virtual machine of SoftPLC system iComacPLC1.0 were introduced, the function and the development process of instructions library of virtual machine were analyzed. This module provides information of elements in ladder diagram. According with IEC 61131-3 standard and adopting the object oriented programming method, the instructions library has many advantages such that it is generic and easy to extend and so on. The flexibility of entire system is increased.
