The characteristic of PLC periodic crash is that the PLC crashes after running for several times, causing program confusion and different fault displays. After restarting, everything is normal again. On site practice suggests that prolonged accumulation of dust is the most common cause of PLC periodic crashes, and regular cleaning of the PLC rack slot interface should be carried out. When cleaning, compressed air or “leather tiger” can be used to blow away the dust on the control board first, and then 95% alcohol can be used to clean the slot and control board plug. After cleaning, carefully assemble and restore the power to normal operation.

PLC program loss is usually caused by poor grounding or incorrect wiring, incorrect operation, and interference.

1. The PLC host and module must have a good grounding, usually connected to the switch cabinet shell by the host shell. When there is a poor grounding, it should be considered to use multi-stranded copper wire, and directly grounded from the host grounding terminal to ensure good grounding. In addition, it should be ensured that the negative pole of the 24V DC power supply of the I/O module has a good grounding.

2. The phase wires of the host power wiring terminals must be connected correctly, otherwise the host may not start, often resulting in errors or program loss. To prevent program loss, it is necessary to prepare a program package. A complete program needs to be packaged in advance in case of urgent need. When using a programmer to find faults.

Place the lock switch in the vertical position and then pull it out to protect the memory. If you want to disconnect the PLC system power supply, you should first disconnect the host power supply, and then disconnect the I/O module power supply. If you first disconnect the I/O part power supply, or if the I/O part and the host power supply are disconnected at the same time, it will cause incorrect values to be stored in the power outage processing room and cause program confusion. 5. If the PLC program is lost due to interference, the handling method can refer to the handling of faults caused by PLC interference, and try to suppress and weaken the interference as much as possible.
