Abstract:
PROBLEM TO BE SOLVED: To avoid repeating re-trys under the same condition by providing a device that changes conditions to halt the re-try corresponding to the number of times or re-trys.
SOLUTION: A re-try condition decision table 34 is prepared from a re-tray condition decision data table 32 and a re-try number-of-time decision data table 33, and a re-try condition selector 38 selects necessary data from the re-try condition diction table 34 to from re-try decision data 37. During operation, an abnormal state decision device 39 checks agreement with the re-try condition data that can be retrieved according the number of time of re-try to find the occurrence of an abnormal state. When the number of time of re-try is not set, it is judged to be an abnormal state. When the number of times of re-trys is set, one is added to the number of times of re-try to renew the retrieved data for re-try conditions and halts re-try. Therefore, conditions to halt re-trys can be change corresponding to the number of time of re-try.
