Interference from grounded system chaos

Grounding is one of the effective means to improve electromagnetic compatibility (EMC) of electronic equipment. Correct grounding can not only suppress the influence of electromagnetic interference, but also suppress the external interference of the equipment; and the wrong grounding will introduce serious interference signals, so that the PLC system will not work normally.


The ground of the PLC controller control system includes system ground, shield ground, AC ground and protection ground. The disturbance of the grounding system to the PLC controller system is mainly due to the uneven distribution of potential at each grounding point. There is a ground potential difference between different grounding points, causing ground loop current and affecting the normal operation of the system. For example, the cable shielding layer must be grounded at one point. If both ends A and B of the cable shielding layer are grounded, there is a ground potential difference, and a current flows through the shielding layer. When an abnormal state such as a lightning strike occurs, the ground current will be larger.


In addition, the shielding layer, the grounding wire and the earth may constitute a closed loop. Under the action of the changing magnetic field, an induced current may appear in the shielding layer, and the signal loop is interfered by the coupling between the shielding layer and the core wire. If the system ground and other grounding treatments are confusing, the generated ground loop may generate unequal potential distribution on the ground line, affecting the normal operation of the logic circuit and the analog circuit in the PLC controller. The logic voltage interference tolerance of the PLC controller is low, and the distribution of the logic ground potential easily affects the logic operation and data storage of the PLC controller, resulting in data confusion, program runaway or crash. The distribution of the analog ground potential will result in a decrease in measurement accuracy, causing severe distortion and malfunction of the signal measurement and control.


System internal interference

News Print Paper Sheeting Machine is mainly generated by mutual electromagnetic radiation between internal components and circuits of the system, such as the mutual radiation of logic circuits and their influence on analog circuits, the interaction between analog ground and logic ground, and the mismatch between components. This belongs to the PLC controller manufacturer's electromagnetic compatibility design inside the system. It is more complicated. As an application department, it cannot be changed. It does not need to be considered too much, but it is necessary to select a system with more application performance or test.
