V. Common Faults and Solutions

Communication Faults
Possible Causes: Damage to communication cables, such as cable aging, breakage, poor contact, etc., leading to signal transmission interruption; hardware faults of communication interfaces, such as damage to interface chips, loose solder joints, etc.; incorrect configuration of communication protocols, inconsistent communication protocols between different devices, making it impossible to correctly parse data; network interference, strong electromagnetic interference in industrial environments, affecting the quality of communication signals.

Solutions: Check the communication cables for obvious signs of damage, and replace the cables if any; for poor contact, re-plug the cable connectors to ensure a firm connection. If a hardware fault of the communication interface is suspected, use professional testing tools, such as oscilloscopes, logic analyzers, etc., to detect the interface circuit and replace the faulty components after identification. Carefully check the communication protocol configuration to ensure it is consistent with the communicating device, and reconfigure the protocol parameters if necessary. For network interference, the communication cables can be shielded by using shielded cables and reliably grounding the shield; install signal filters on the communication lines to reduce the impact of interference signals.

Solutions: Calibrate or test the sensor using a standard signal source, and replace the sensor in time if it is damaged. Check the input interface circuit, and judge whether there are damaged components by measuring circuit parameters, such as resistance value, capacitance value, etc., and replace the corresponding components if any. For data transmission problems, check the communication link to ensure network stability, and redundant communication links can be used to improve reliability; at the same time, strengthen electromagnetic shielding to reduce the impact of interference on data transmission.

Controller Crash or Restart
Possible Causes: Hardware overheating, long-term high-load operation or poor heat dissipation, leading to excessive internal temperature of the controller, affecting the normal operation of the chip; software faults, such as program loopholes, memory overflow, etc., leading to abnormal system operation; power supply faults, unstable input power voltage, excessive ripple, or damage to the power module, affecting the normal power supply of the controller.

Conduct a comprehensive inspection of the software, update to the latest version to fix possible program loopholes; optimize the program code to avoid problems such as memory overflow. Check the input power voltage, use a multimeter to measure whether the voltage is within the normal range, and install a voltage stabilizer if the voltage is unstable; replace the power module with the same specification if it is damaged.
