摘要
本文构建了基于LabVIEW的PLC控制系统的实时监控平台。该控制系统是利用VISA技术实现了主控机界面和西门子PLC S7-200通信,并使用TCP/IP协议将采集的数据在总机上实时显示。
Real time control and state monitoring platform of PLC control system was designed based on LabVIEW. This platform used VISA technology to realize serial communication between PC and Siemens S7-200. And TCP/IP protocol was used in this system to show the acquired data.
