摘要
在嵌入式硬件平台上的基础上,用软件实现传统PLC的功能,从整体上设计了符合IEC61131标准的嵌入式软PLC系统.设计由开发系统和运行系统两大部分组成,其中,开发系统实现梯形图的编辑和编译,运行系统实现软PLC虚拟机的控制功能.介绍了各个模块的实现方法,经实验证明满足控制要求.
On the basis of the embedded hardware platform,this essay implies software to realize the traditional function of PLC,thus designs a embedded soft PLC system that is up to the IEC61131 standard.The system is consist of development system,which realizes the ladder diagram and running system,which realizes the controlling function of soft PLC virtual machine.The essay introduces the method of implementation of each module,which is testified to meet the need of control.
