摘要
应用图形化编程语言LabVIEW实现PC机与西门子PLC串口通信,通过使用ActiveX控件-MsComn实现中断读取下位机的数据,提高监测系统实时性与可靠新,应用西门子的S7-200的模拟电位器,实现了温度和压力的监测系统设计.
Serial port communication between PC and Siemens PLC is realized by using the graphic programming language LabVIEW.By applying MsComn control of ActiveX,the data of the lower computer during its interruption can be read,thus improving the real-time and reliability of the system.Using the Siemens S7-200 potentiometer simulator,the monitoring system design of temperature and pressure is realized.
