摘要
利用LabVIEW编程灵活方便的特点,本文在LabVIEW8.2的环境下实现PC与PLC的通信功能,使PLC不但具备控制功能,而且能将检测到的数据送到PC机。利用RS-485串口实现主机与PLC的串行通信,从而实现对光栅刻划机的工作环境温度的监控。
Based on the flexible and easy programming of LabVIEW, this paper realized communication functions between PC and PLC under environment of LabVIEW. It makes PLC not only have control function but also send the date to PC by serial port. Realizing serial communication between PC HOST and PLC using RS-485, it can implement ambient temperature monitoring of grating ruling engine.
