CONTROL LOGIC MANAGEMENT DEVICE

PROBLEM TO BE SOLVED: To facilitate grasp of a cause spot of an alert, etc.SOLUTION: In a control logic management device, a control logic drawing storage section 30 stores data on a control logic drawing 80 describing a control logic of a control program executed by a control device 14 of a control object 10. A tracking rule storage section 32 stores data on a tracking rule 82 that is predetermined to track a wire connection of the control logic. A control logic tracking section 34 performs tracking processing to identify a spot of a cause of an alert and a tracking route to the spot in the control logic by tracking the wire connection of the control logic in a reverse direction from an output terminal of an alert control signal for outputting the alert. Tracking is performed according to a computation state 64 of the control program, an operation state 66 of the control object 10, and the tracking rule 82. A display information generation section 36 generates display information 86 reflecting the obtained tracking route onto the control logic drawing 80.
