LC采用一种可用于内部存储程序的可编程存储器，执行顺序控制、逻辑运算、定时、与算术操作等面向用户的指令，并可以通过模拟输入/输出控制各种类型机械或者生产过程。PLC不仅是一种逻辑电路，还是一种与硬件结合紧密的语言，在半导体领域的应用很广泛。PLC和其相关的外部设备都应基于容易与工业控制系统形成一个整体，易于扩展其功能的原则进行设计。
一、PLC主机系统问题
PLC由于其实用性而受到工业领域的青睐，因此对于PLC技术的研究也日益受到相关企业的重视。PLC主机系统*容易发生故障的地方一般在电源系统和通讯网络系统，电源在连续工作、散热中，电压和电流的波动冲击是不可避免的。通讯及网络受外部干扰的可能性大，外部环境是造成通讯外部设备故障的因素。系统总线的损坏主要由于现在PLC多为插件结构，长期使用插拔模块会造成局部印刷板或底板、接插件接口等处的总线损坏，在空气温度变化、湿度变化的影响下，总线的塑料老化、印刷线路的老化、接触点的氧化等都是系统总线损耗的原因。所以在系统设计和处理系统故障的时候要考虑到空气、尘埃、紫外线等因素对设备的破坏。目前PLC的主存储器大多采用可擦写ROM，其使用寿命除了主要与制作工艺相关外，还和底板的供电、CPU模块工艺水平有关。而PLC的处理器目前都采用高性能的处理芯片，故障率已经大大下降。对于PLC主机系统的故障的预防及处理主要是提高集中控制室的管理水平，加装降温措施，定期除尘，使PLC的外部环境符合其安装运行要求;同时在系统维修时，严格按照操作规程进行操作，谨防人为的对主机系统造成损害。
