La mise à la terre à double-extrémité et à une-extrémité sont deux modes de mise à la terre de blindage, tandis que les méthodes de mise à la terre de la couche de blindage du système incluent la mise à la terre flottante basse, directe et la mise à la terre capacitive.
The PLC system is a high-speed and low-frequency control system device, and it is most suitable to use the direct grounding method. Affected by factors such as the distributed capacitance of the signal current and the filtering of the input device, the signal exchange frequency between the devices is lower than 1MHz, so the grounding method of the PLC control system is generally grounded at one point or in series.
