Working Principle

Troubleshooting

• Communication Failure
• Check if the communication cable is firmly connected, free of damage, or interference.
• Confirm that the communication parameter settings match those of the connected device.
• View the system diagnostic log, judge the problem based on error codes, and contact technical support in case of protocol incompatibility or interface chip failure.
• Power Failure
• Use a multimeter to measure the voltage at the module's power terminal to ensure it is within the normal range.
• Check if the power cable is well-connected, whether the power adapter works normally, and if there is a fuse, check if it is blown.
• Abnormal Input/Output
• Check if devices connected to the module, such as sensors and actuators, work normally.
• View the signal indicator lights on the module to confirm the signal transmission and reception status.
• Use relevant tools to measure the parameters of the module's input and output terminals, compare them with the rated values. If abnormal, it may be an internal circuit failure, requiring further inspection or replacement.
• Environmental Issues
• Confirm that the module's installation environment temperature is within the specified range, avoiding direct sunlight and proximity to heat sources.
• Check the installation location for dust, moisture, etc., and clean it in a timely manner to prevent failures caused by poor heat dissipation or short circuits.
• Ensure the module is kept away from electromagnetic interference sources such as large motors and transformers, and shield communication and power cables when necessary.
