Diagnosis facility and diagnostic method for monitoring performance of a technical plant

A diagnostic method for monitoring the performance of a technical plant, comprising:

• storing at least one data set characterizing performance of the technical plant in a memory;
• determining a diagnostic report on the performance of the technical plant using the at least one data set and a predetermined self-organizing map;
• determining a duration of the execution of each step of a cycle that is to be checked in a step sequence during the performance of the technical plant with repeatedly run step sequences;
• storing previously determined durations as a respective coordinate of the at least one data set during the performance of the technical plant with the repeatedly run step sequences, the at least one data set comprising an n-tuple with a predetermined number n of coordinates;
• and
• detecting and displaying deviations of a time response in the cycle that is to be checked from fault-free cycles by evaluating the at least one data set during the performance of the technical plant with the repeatedly run step sequences, using the self-organizing map, n-tuples with the predetermined time responses for fault-free cycles of the step sequence being stored on the node of the self-organizing map.

A non-transitory computer-readable medium encoded with a computer program executed by a computer that causes monitoring performance of a technical plant, comprising:

• program code for storing at least one data set characterizing performance of the technical plant in a memory;
• program code for determining a diagnostic report on the performance of the technical plant using the at least one data set and a predetermined self-organizing map;
• program code for determining a duration of the execution of each step of a cycle that is to be checked in a step sequence during the performance of the technical plant with repeatedly run step sequences;
• program code for storing previously determined durations as a respective coordinate of the at least one data set during the performance of the technical plant with the repeatedly run step sequences, the at least one data set comprising an n-tuple with a predetermined number n of coordinates;
• and
• program code for detecting and displaying deviations of a time response in the cycle that is to be checked from fault-free cycles by evaluating the at least one data set during the performance of the technical plant with the repeatedly run step sequences, using the self-organizing map, n-tuples with the predetermined time responses for fault-free cycles of the step sequence being stored on the node of the self-organizing map.
