| Abstract: | The significance and necessity of the anti-interference design of the programmable logic controller (PLC)control system is described briefly and the general measures of the anti-interference design of PLC control system is summarized. It mainly discusses the measures of the anti-interference design of PLC control system in five aspects, that is, power, grounding, I/O signal, external wiring and hardware filtering & software design. The anti-interference design of PLC control system is very complex. The specific problem has to be analyzed so as to ensure the safe and reliable working of PLC control system. |
