METHOD FOR ANALYZING TROUBLE IN PRODUCTION LINE

摘要

PURPOSE:To specify an action step and its action element related to the action element, which is a cause of trouble, by collating an operated manual operation means with a data map to specify a corresponding step rudder action element group, and analyzing this group to specify an inoperative action element. CONSTITUTION:A CPU62 judges whether a manual operation switch, corresponding to a manual operation element, is operated placed in an on-condition or not, in the case of inputting an analysis request signal, to confirm a corresponding manual operation element Xx in the case of the on-condition. Successively, the manual operation element Xx is collated with a step data map read from a hard disc 66, and an intermediate output action element Mx is specified from a corresponding relation between the manual operation element and the intermediate output action element, to specify a step rudder action element group Gxs related to the intermediate output action element Mx. Next, an interlock in the step rudder action element group Gxs is analyzed, and an inoperative action element, which is a cause of taking an inoperative condition by the intermediate output action element Mx, is specified.
