Phenomenon: The module cannot communicate normally with other devices, such as failing to connect to the host computer or experiencing data transmission errors.

Possible Causes: Poor communication cable connection, incorrect communication parameter settings, damaged communication interface, electromagnetic interference, etc.

Solutions: Check if communication cables are firmly connected, confirm that communication parameters (such as baud rate, data bits, parity) match other devices, try replacing the communication interface, and shield communication lines to reduce electromagnetic interference.

Phenomenon: The collected analog signals do not match actual values, or signals fluctuate significantly and unstably.

Possible Causes: Sensor failure, open or short circuit in input cables, damaged module input channels, signal interference, etc.

Solutions: Check if the sensor is working properly, use a multimeter to measure the continuity of input cables, inspect input channel status through the module's self-diagnosis function, and add filtering measures to input signals to eliminate interference.

Phenomenon: The output analog signals cannot correctly control external devices, such as inconsistent output values with set values or no output signals.

Possible Causes: Poor output cable connection, load failure, damaged module output channels, incorrect output parameter settings, etc.

Solutions: Check output cable connections, confirm that load devices are working properly, view output channel status through the module's diagnostic function, and reset output parameters to ensure they match actual requirements.

Phenomenon: The module has no power indication and cannot work normally.

Possible Causes: Abnormal input power voltage, poor power cable connection, faulty internal power circuit of the module, etc.

Solutions: Use a multimeter to measure the input power voltage, ensure it is within the range of 24VDC (±20%), check if power cables are firmly connected, and contact professional maintenance personnel for repair or module replacement if the internal power circuit is faulty.
