<p>PROBLEM TO BE SOLVED: To provide a ladder program diagnostic method and an equipment diagnostic device capable of easily releasing a trouble in equipment to be controlled at its sequence and shortening release time. SOLUTION: The equipment diagnostic device 3 is constituted of a detection means 4, a cause tracing means 5, a display means 6 consisting of a monitor, and a storage means 7. A sequencer 2 for controlling equipment transmits/ receives controlling output and input signals Y, X to/from equipment 1 such as a robot, and when abnormality occurs in the equipment 1, the sequencer 2 sends a signal indicating the occurrence of abnormality to the device 3. The detection means 4 in the device 3 detects the occurrence of abnormality in the equipment 1 from the detection signal indicating the occurrence of abnormality and the tracing means 5 uses the detection signal inputted from the means 4 as a trigger and executes the tracing of a cause and the diagnosis of a trouble point from a rudder program stored in the storage means 7 and contact information indicating the operation state of the program on the basis of a cause tracing program (algorithm).</p> |
