Abstract:Introduced communication between LabVIEW and the PLC, and the use of simulation platform, designed a LabVIEW-based control system and PLC. Mainly to the physical simulation of the PLC and the control equipment, use software to achieve the physical PLC system.In view of the characteristics of virtual machines, if the function of PLC software, and as long as the appropriate configuration on the computer data input and output modules, it can be the same as the use of physical PLC. In addition, the development of LabVIEW virtual instrument software also has a friendly graphical interface, designed to facilitate the development of visual control of the scene object model.Therefore, the development of the whole project from the point of view, in order to quickly and effectively conduct software development, software development tools make full use of the wide range of functions, where appropriate, reduce the workload, we chose the LabVIEW software as the subject of this thesis development tools. The experimental results show that: the control system has been designed to achieve the desired effect. The system can make some appropriate modifications according to the practical application, so as to make better applications.
