 Diagnose the fault through PLC program. The vast majority of faults presented by PLC control systems are detected through PLC program checks. Partial faults can directly display alarm factors on the screen; Although there are some alarm messages on the screen, they do not directly reflect the factors causing the alarm; Some faults do not generate alarm messages, and only some actions are not performed. Monitoring the operation of the PLC program is a useful method for diagnosing faults in the latter two situations. Regarding simple faults, information can be displayed based on the status of the program passing through the PLC, monitoring the status of inputs, outputs, and symbolic bits, and tracking the operation of the program. For complex faults, it is necessary to use a programmer to track the operation of the program. If a certain water pump is not working, it was found that the corresponding PLC output port is 0. Therefore, after checking the program, it was found that the hot water pump is still controlled by the water temperature. If the water temperature is not good, the PLC will not output. After raising the water temperature, the fault was solved.
