摘要
针对传统程序设计方法难以对具有并发、协调、竞争等复杂事件的PLC控制系统编程的问题,探讨了一种基于Petri网模型的PLC程序设计方法.该方法利用Petri网的图形性质和对并发事件建模的能力,可简便、直观地构建PLC控制系统程序,并能对控制系统性能进行分析,以确认程序的合理性.
The conventional program design method is unable to solve the control problem of PLC control system with parallel,coordination,competition.To solve the problem,a PLC program design method based on Petri net is presented.Petri net is graphics model and is able to model for parallel system,so the program of PLC control system can be designed conveniently and audiovisually,the control system can be analyzed to confirm the reasonableness of program.
