<p>PURPOSE:To provide the production management device which improves the realiability of display of abnormality occurrence. CONSTITUTION:Data inputted from an input device 8 is made into a hierarchical structure based on data stored in an event various element data storage part 20, and is stored in a picture control data storage part 5. Meanwhile, this data is reconstituted into a ladder sequence program by a ladder generating part 21 and is stored in a sequence ladder program storage part 11. A picture control part 4 displays event information of the programmable logic controller 1 on a display device 6 based on programs stored in these storage parts in response to a request.</p> |
