基于VB和PLC的虚拟仿真实验项目的研究与实现

Research and Implementation of Virtual Simulation Laboratory Based on VB and PLC

本文利用VB软件开发虚拟控制对象,利用协议转换模块建立VB与PLC间交互通信机制,从而实现PLC对虚拟控制对象的常规实验控制和程序验证,最终建立一套完整虚拟仿真实验项目。

Virtual control objects are designed by using the VB software in this paper. An interaction and communication mechanism between VB and PLC is established by using the protocol conversion module. The conventional experimental control and program verification can be realized by the PLC and virtual control objects.
