On-site electromagnetic interference is one of the most common and easily affecting factors of the system reliability in the PLC control system. It is called to solve the symptoms first, find out the problem, and then propose solutions to the problem. Therefore, the source of on-site interference must be known. (1) Interference sources and general classification
Most of the interference sources that affect the PLC control system are generated at the position where the current or voltage changes sharply. The reason is that the current changes to generate magnetic field, which generates electromagnetic radiation to the equipment; The magnetic field changes to generate current, and the electromagnetic wave is generated at high speed. Generally, electromagnetic interference is divided into common mode interference and differential mode interference according to different interference modes. Common mode interference is the potential difference between the signal and the ground, which is mainly formed by the superposition of the power grid connection, the ground potential difference and the common state (in the same direction) voltage induced by space electromagnetic radiation on the signal line. Common mode voltage can be converted into differential mode voltage through asymmetric circuit, which directly affects the measurement and control signal and causes component damage (this is the main reason for the high damage rate of I/O modules in some systems). This common mode interference can be DC or AC. Differential mode interference refers to the interference voltage acting on the two poles of the signal, which is mainly formed by the coupling induction of the space electromagnetic field between the signals and the conversion of the common mode interference by the unbalanced circuit. This interference is superimposed on the signal and directly affects the measurement and control accuracy.
