以电炉温度控制系统为研究对象,介绍了系统的工艺过程,给出了硬件接线图,软件梯形图和部分控制程序,对系统的每个环节进行了较详细的研究,为其他温度控制系统的PLC改造提供了参考依据.
Taking the electric furnace temperature control system as the research object, the process of the system is introduced. The hardware wiring diagram, software ladder diagram and partial control program are given. Each link of the system is studied in more detail. The temperature control system for other temperature control systems PLC transformation provides a reference.
