The normal power supply of PLC system is supplied by the power grid. Due to the wide coverage of the power grid, it will be subject to all spatial electromagnetic interference and induce voltage on the line. In particular, changes in the power grid, surges in knife switch operation, starting and stopping of large power equipment, harmonics caused by AC and DC drives, and transient impact of short circuit in the power grid are all transmitted to the power source through transmission lines.
Cabinet interference
High-voltage electrical appliances in the control cabinet, large inductive loads, and disordered wiring are easy to cause a certain degree of interference to the PLC.
Interference from signal line
All kinds of signal transmission lines connected with the PLC control system, in addition to transmitting various kinds of effective information, 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 by the transmitter power supply or the power supply of the shared 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.
