系统接地方式有浮地方式、直接接地方式和电容接地三种方式。对PLC控制系统而言，它属于高速低电平控制装置，应采用直接接地方式。由于信号电缆分布电容和输入装置滤波等的影响，装置之间的信号交换频率一般都低于1MHz，所以PLC控制系统接地线采用一点接地和串联一点接地方式。集中布置的PLC系统适合并联一点接地方式，各装置的柜体中心接地点以单独的接地线引向接地极。如果装置间距较大，应采用串联一点接地方式，用一根大截面铜母线（或绝缘电缆）连接各装置的柜体中心接地点，然后将接地母线直接连接接地极。

There are three grounding methods for the system: floating grounding, direct grounding, and capacitive grounding. For PLC control systems, they belong to high-speed low-level control devices and should be directly grounded. Due to the influence of distributed capacitance of signal cables and filtering of input devices, the signal exchange frequency between devices is generally lower than 1MHz. Therefore, the grounding wire of PLC control system adopts one point grounding and series one point grounding methods. The centrally arranged PLC system is suitable for parallel connection with a single point grounding method, and the central grounding point of each device’s cabinet is led to the grounding electrode with a separate grounding wire. If the distance between devices is large, a series connection with a single point grounding method should be adopted. A large cross-section copper busbar (or insulated cable) should be used to connect the central grounding point of each device cabinet, and then the grounding busbar should be directly connected to the grounding electrode.
