The normal power supply of PLC system is supplied by the power grid. Due to the wide coverage of the power grid, voltage and circuit will be induced on the line due to all spatial electromagnetic interference. In particular, changes in the power grid, switching surges, startup and shutdown of large power equipment, harmonics caused by AC and DC rotating devices, and short circuit transient impact of the power grid are all connected to the power supply side through the transmission line. PLC power supply usually adopts isolated power supply, but its isolation is not ideal due to its mechanism and manufacturing process factors. In fact, due to the existence of distributed parameters, especially distributed capacitance, absolute isolation is impossible.

All kinds of signal transmission lines connected to the PLC control system, in addition to transmitting effective signals, will always be invaded by external interference signals. There are two main ways of this interference: one is the power grid interference connected in series through the power supply of the transmitter or common signal instrument, which is often ignored; The second is that the signal line is interfered by the induction of space electromagnetic radiation, that is, the external induction interference on the signal line, which is very serious. The interference introduced by the signal will cause the I/O signal to work abnormally and the measurement accuracy will be greatly reduced, and in serious cases will cause damage to the components. For the system with poor isolation performance, it will also cause mutual interference between signals, cause common ground system bus backflow, and cause logic data change, misoperation and crash. The number of I/O module damage caused by signal introduction interference in PLC control system is quite serious, and there are many system failures caused by it.
