摘　　要：近年来,西门子PLC的功能不断改进,从过去的接线控制逻辑到如今的存储控制逻辑,其运动控制和过程控制均有了较大的突破。西门子PLC广泛用于火力发电厂的各种控制系统中。但是,由于西门子PLC非常容易受到环境干扰,若工作环境太差,将直接影响西门子PLC的良性运行,从而导致其无法执行功能。因此,讨论西门子PLC在电厂应用中的常见问题和处理方法具有重要意义。In recent years,the functions of Siemens PLC have been continuously improved.From the wiring control logic of the past to the storage control logic of today,its motion control and process control have made great breakthroughs.Siemens PLC is widely used in various control systems of thermal power plants.However,Siemens PLC is very susceptible to environmental interference,if the working environment is too bad,it will directly affect the benign operation of Siemens PLC,resulting in its inability to perform functions.Therefore,it is of great significance to discuss the common problems and treatment methods of Siemens PLC in power plant applications.
