The method involves recording of a production step duration, which are collected for executing a production step by means of a production means (1), whereby values (T1,T2) are gathered for the production step duration during a learning phase (2) within the presupposed error free condition of production means. The method also involves determination of at least first threshold value on the basis of the collected values of the production step duration, measuring of the current value (Ti) of the production step duration during the learning phase following production phase (3), comparison of the current value of the production step with the first threshold value, and generating an error message (ALARM1) after over or falling below of the first threshold value. Independent claims are also included for the following: (A) Device for monitoring condition of a production means of an automation system; (B) Automation system. |
