Interference from a chaotic grounding system, which is one of the most effective ways to increase the Electromagnetic compatibility of an electronic device. The correct grounding can not only restrain the influence of electromagnetic interference, but also restrain the equipment to send out interference. But the wrong grounding will lead to serious interference signal, and the system will not work properly. The Ground Wire of control system includes system ground, shield ground, exchange ground and protection ground. The disturbance of the PLC system caused by the confusion of the grounding system is that the potential distribution of each grounding point is uneven, and the ground potential difference exists between different grounding points, which causes the current of the ground loop and affects the normal operation of the system. For example, the cable shield layer must be grounded at one point. If both ends of the Cable Shield Layer A and B are grounded, there will be a potential difference between the ground and current flowing through the shield layer. In addition, the shielding layer, the ground wire and the earth may constitute a closed loop. Under the effect of changing magnetic field, induced current may appear in the shielding layer, which may interfere the signal loop through the coupling between the shielding layer and the core wire. If the grounding system is confused with other grounding systems, the generated ground circulation may produce unequal potential distribution on the ground wire, which affects the normal work of logic circuit and analog circuit. The interference limits of logic voltage are low, and the distribution interference of logic ground potential easily affects the logic operation and data storage, resulting in data confusion, program running or crash. The distribution of analog ground potential will lead to the decrease of measurement precision, and cause the serious distortion and misoperation of signal measurement and control. Beijing Pinghe isolator can also effectively solve the problem of signal common ground
