plc主机系统
plc主机系统最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最大因素之一。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的中央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。
