基于组态软件的PLC控制系统半实物仿真

Semi-Physical Simulation of PLC Control System Based on Configuration Software

针对PLC控制系统软件现场调试中需要连接执行器,调试成本高、调试周期长的缺陷,提出一种利用组态软件与PLC工业控制系统的半实物仿真方法。通过组态王软件与FX2N系列PLC电梯控制仿真系统,构建了组态王6.5图形界面设计、数据库建立、动画连接,并设置了组态软件与PLC间的通信格式。对3层电梯PLC控制系统的仿真运行和分析表明:上位监控计算机可以在脱离实际物理控制对象的情况下,实现对PLC控制程序的调试和半实物仿真运行。

Generally,PLC actual control program with actuator cost high,but long debugging cycle.A semi-physical simulation method is introduced,by configuration software and PLC constructed industrial control system.Through the simulation system of elevator control system constructed by Kingview software and FX2N series of PLC,KingView 6.5 GUI designe,database setup,dynamic drawing connecting,and communication format seting between configuration software and PLC are presented in detail.Through the test and analysis of this elevator control simulation system,supervisory control may realize the debugging and semi-physical simulation of control system.
