According to this configuration, the operator A2 can immediately recognize the previously approved change information CHI m (or the initial operation program OP 0 ), and the approved change information CHI m (or the initial operation program OP 0 ). OP 0 ) can be selected to be restored.
- the processor 50 may display only the change information CHI m (or the initial operation program OP 0 ) for which no abnormality has been detected in the past in the selection image SIM described above. Specifically, when the processor 50 detects an abnormality during the execution of the operating program OP n , the change history data HIS stored in the storage unit 52 stores the change information CHI corresponding to the executed operating program OP n . An anomaly flag F2 indicating that an anomaly has been detected is added as incidental information to n . An example of such change history data HIS is shown in Table 2 below.
- an abnormality flag F2 is assigned to change information CHI 3 indicating the third change CH 3 corresponding to "VER.003” (that is, the "abnormality flag” is " ⁇ ”), therefore, it indicates that an abnormality was detected during the execution of the operation program OP3 after the change CH3 .
- the abnormality flag F2 is not given (that is, the "abnormality flag” is "x"), therefore, after the change CH 1 This indicates that no abnormality was detected during the execution of the operating program OP1.
- the processor 50 refers to the presence or absence of the abnormality flag F2 ("O" or "X") for each of the change information CHI n (and the initial operation program OP0 ) stored in the change history data HIS. It is possible to determine whether or not an abnormality has been detected in the operation program OPn corresponding to the change information CHI n .
