PLC controller is suitable for parallel one point grounding method. The base grounding address of each equipment is led to the grounding electrode by its own grounding wire. The PLC controller with scattered placement shall be connected with one point grounding method in series. The grounding resistance of the grounding electrode is less than 2 Ω， The grounding electrode is best buried 10-15m away from the building, and it is necessary to connect the PLC controller to the strong current equipment at a distance of more than 10m. If expansion units are to be used, their address should be connected with the address of the root unit.
When the signal source is grounded, the shielding layer shall be grounded on the signal side; When the signal source is not grounded, it shall be grounded on the PLC controller side. When there is a joint in the signal line base, the shielding layer shall be firmly connected and insulated. Each shielding layer shall be connected well with each other. Select the proper grounding point single point grounding, and prevent multi-point grounding.
6. equipment selection.
In selecting equipment, we should first understand the anti-interference targets given by the domestic PLC manufacturers, such as common mode rejection ratio, differential mode rejection ratio, withstand voltage capacity, what large electric field strength and how high frequency magnetic field intensity environment are allowed to operate, and select the commercial products with high anti-interference capability, such as selecting floating ground technology, programmable controller with good barrier performance and HMI of human-machine interface.
