PROBLEM TO BE SOLVED: To provide a digital protection controller capable of swiftly and easily identifying a failure point by displaying a prepared drawing data together with a state of control signal at a monitoring defect detection.SOLUTION: In order to detect a monitoring defect, a monitoring defect detection section 11 collects monitoring information from a protective control function 2, and a control signal collection section 12 collects control signals from the protective control function 2. A monitoring result data collection section 13 collects, as a monitoring result data, control signals at a point when the monitoring defect detection section 11 detects a monitoring defect, and a monitoring result data storage section 14 stores the same. A literal data storage section 15 stores a literal data including a drawing data of a digital protection controller 1. A monitoring result data display unit 16 displays a state of the control signals on the drawing data in combination of the monitoring result data and the literal data at a point when a monitoring defect is detected.SELECTED DRAWING: Figure 1 |
