摘　　要：介绍了一种用VisualC++语言实现的软件PLC,在编程环境中,可用梯形图及语句表编辑控制程序,编辑范围不受限制,编程时遵照普通PLC的规则即可;在执行环境中,可执行PLC程序并随时监控执行情况.该软件PLC易于实现硬件无关性.This paper introduces a softPLC with Visual C＋＋. In programming enviroment, control programm can be edited by ladder diagram and instruction list.The edited scope is not limited, and the rule of programming is the same as normal PLC. In execution enviroment, the softPLC program can be excuted and monitored. The SoftPLC is easy to realize hardware independence.
