VARIABLE CONTROL LAYER DEPTH MALFUNCTION CHECKING APPARATUS AND VARIABLE CONTROL LAYER DEPTH MALFUNCTION CHECKING METHOD

摘要

The present invention comprises the steps of displaying, in the control unit, a control screen visualized as an image corresponding to each module of the system at an initially set control layer depth level, and, in the system, for each scheduled preset time unit, the initially set control layer depth A step of diagnosing a module failure in a control unit organized by level, and when a failure is diagnosed as a result of the diagnosis in the system, transmitting information about the module for which the failure is diagnosed together with a failure warning to the control unit; , generating a failure warning based on the failure warning transmitted from the system and information on the module whose failure has been diagnosed, and converting the image corresponding to the module in which the failure occurred to a failure display image and displaying; In the unit, when the input of the control layer depth selection signal is detected, requesting the system for fault diagnosis with the control layer depth corresponding to the control layer depth selection signal, and in the system, organizing the control layer depth level requested by the control unit Diagnosing the failure of the module in the specified control unit, and in the system, transmitting information about the module whose failure is diagnosed at the requested control layer depth level to the control unit, and in the control unit, to the module transmitted from the system A control layer depth variable fault diagnosis method comprising displaying an image corresponding to a control unit of a control layer depth level to which the faulty module belongs, based on the information about the faulty module, and displaying the faulty module as a fault indication image.
