摘要
阐述了PLC控制系统存在的主要干扰源,针对干扰源的不同途径,从硬件和软件两方面,阐述了电源抗干扰设计措施、输入输出电路抗干扰设计措施,以及数字滤波和软件容错等抗干扰措施,对PLC控制系统具有使用价值。
This paper discusses the main disturbance sources existing in PLC control system.According to different channels of anti-disturbance sources,some anti-disturbances design measures about power supply,and input and output circuits,some anti-disturbance measures about digital wave filtering and software error-permitting and so on are also discussed in the view of software and hardware,which can be of application value to PLC control system.
