The control control unit 120 that has received the fault diagnosis data from the system 300 through the control communication module 150 stores a fault display image corresponding to the identifier of the faulty module based on the fault diagnosis data to the control data storage unit 130 . ), and reconstructs a control screen in which an image corresponding to a module corresponding to a corresponding module identifier is replaced with a failure indication image on the control screen currently displayed on the display unit 140 . The reconstructed screen is displayed on the display unit 140 under the control of the control unit 120 (S120).

In step S120 , when a depth change signal is applied from the operator input unit 120 while the control screen is displayed on the display unit 140 ( S130 ), the control control unit 120 controls the image corresponding to the changed control layer depth level. is retrieved from the control data storage unit 130 to reconfigure the control screen, and then the reconstructed control screen is displayed through the display unit 140 (S140). In this case, according to the matters the control operator wants to check or other requirements, it may be set to the upper control layer depth level or the lower control layer depth level, for example, the control currently displayed on the display unit 140 . If the screen is the depth level of the control hierarchy of equipment or equipment unit, the control screen according to the depth level of the upper control hierarchy may be a control screen displayed for each floor, and the lower control hierarchy depth level is a failure by replacing parts when a failure occurs. It may be a control screen displayed in units that can be repaired. In this case, the faulty module can be easily and intuitively recognized, and since the recognized faulty module is at a level that can be repaired by replacing parts, It works.

In this embodiment, while displaying the reconfigured control screen, the control control unit 120 requests a fault diagnosis to the system 300 through the control communication module 150 to diagnose the fault with the changed control layer depth level ( S145).

The system control unit 320 controls the module agent 330 to diagnose a failure based on the control layer depth level information included in the failure diagnosis request according to the failure diagnosis request received from the control unit 100 in S145, and the module The agent 330 diagnoses a failure at the control layer depth level, and transmits the identifier and status information of the module in which the failure occurred to the system control unit 320 , and the system control unit 320 transmits the system communication module 310 to the control unit through the system communication module 310 . The failure diagnosis data is transmitted to ( 100 ) ( S350 ).

In step S350 , the control control unit 120 that has received the failure diagnosis data from the system 300 through the control communication module 150 displays a failure display image corresponding to the identifier of the failed module based on the failure diagnosis data as the control data By searching from the storage unit 130 , the image corresponding to the module corresponding to the module identifier is reconstructed in the control screen currently displayed on the display unit 140 , in which the fault indication image is replaced. The reconstructed screen is displayed on the display unit 140 under the control of the control unit 120 (S150).

According to the control layer depth variable fault diagnosis method according to the above-described preferred embodiment of the present invention, since fault diagnosis is performed periodically at a preset time unit in the control unit of the general control layer depth level, detailed Since the failure diagnosis is not performed for each module up to the depth level of the control hierarchy, it is possible to prevent a reduction in the lifespan of the detailed diagnostic module provided for each module, and to prevent the waste of power consumed for failure diagnosis for each module.
