摘要
针对传统的PLC控制实验中实验设备质量大、价格高、占地面积大和维护困难等缺点,提出了一种PLC与组态软件相结合的设计方法.在组态软件中创建虚拟模型作为被控对象,代替实际被控设备,采用虚拟的被控对象即可检验PLC控制程序的正确与否.采用西门子S7-200 PLC与力控V7.0组态软件相结合的方法搭建虚拟仿真实验系统,为PLC的实验教学提供了有利补充.以5层电梯为例,给出了PLC控制虚拟仿真实验系统的开发过程,并对该系统进行了整体测试,证明了所研制实验系统的有效性和可靠性.
In view of the shortcomings of traditional PLC control experiment,such as high quality,high price,large floor area and difficult maintenance,puts forward a design method of the combination of PLC and configuration software.The virtual model is created in the configuration software as the controlled object to replace the actual controlled equipment.The correctness of PLC control program can be verified by using virtual controlled object.It is adopts of Siemens S7-200 PLC and Force Control V7.0 configuration software to build a virtual simulation experiment system,which provides a favorable supplement for PLC experiment teaching.Taking the 5-storey elevator as an example,the development process of PLC control virtual simulation experimental system is given,and the overall test of the system is carried out to prove the effectiveness and reliability of the developed experimental system.
