PURPOSE:To set automatically the state of a data table for control required for rerise by providing a storage means which follows a sequence opposite to that for normalcy at a rerise time in factory automation. CONSTITUTION:When a monitor or the like discriminates conditions of the occurrence of abnormality and indicates the restart operation, an abnormality recovery control part 40 recovers the operation, where abnormality occurs, and completes the operation. Next, all synchronism excluding steps are checked, and the synchronism excluding step coinciding with the work restart operation is found by following a sequence opposite to that for normalcy on a basis of a log table 42. If completion waiting operations of all synchronism excluding steps are restored, the start waiting state is set, and the work restart operation is transmitted to a general control part 30. The control part 30 reads out control information for the work restart operation from a control message table 29 and executes the operation sequence for normalcy. |
