摘　　要：介绍西门子S7-200 PLC和KingSCADA组态软件在温度控制系统中的应用。通过分析温度控制系统的特点,给出了相应的算法,设计了相关的程序模块。利用KingSCADA组态模拟现场画面,操作界面简单明了,方便易用。实际应用表明由S7-200 PLC和KingSCADA组态软件构成的控制系统具有成本低廉可靠性高等特点,同时通过算法直接将频率写入变频器可以节省一个输出模块,节约了设备投资。This paper introduces the application of the S7-200 PLC＆ the KingSCADA configuration software in a terpperature control system,including some control measures and algorithm to be adopted by analyzing.The characteristic of the system. Some relevant program blocks are designed.The menus of the real scenes are simulated with the KingSCADA software.The menus are simple and easy to use.The actual application shows that the control system consisting of the S7-200 PLC and the KingSCADA configuration software is economical and highly reliable.At the same time the algorithm written directly to the frequency converter can save an output module,and that it can reduce the investment in the equipment.
