PROBLEM TO BE SOLVED: To provide a control apparatus capable of monitoring transition of temporary-stored data concerning controlling operation, deleting non-required data from a storing part and assuring a storage region for effective data enabling a cause of trouble to be specified. SOLUTION: This control apparatus comprises a micro-computer 103 for performing a processing for detecting state data as state data expressing a low degree of abnormal state, a processing for recording the state data expressing a low degree of abnormal state in a temporary abnormal data recording region 130 of SRAM114, a processing for detecting the state data of a low degree of abnormal state as state data of a high degree of abnormal state when the same low degree of abnormal state is detected by a predetermined number of times or more, a processing for recording the state data recorded in a ring buffer 113a in an abnormal specified data recording region 140 of SRAM114 when the state data of high degree of abnormal state is detected, and a processing for deleting the state data of a low degree of abnormal state recorded in the temporary abnormal data recording region 130 when the state data of high degree of abnormal state is recorded in the abnormal specified data recording region 140.
