PROBLEM TO BE SOLVED: To reduce an occurence of a trouble such as slowdown.SOLUTION: Assuming that a date, a day of the week, and a time represented by time information of an RTC (Real-Time Clock) is Friday, 1 August, 2014, 10:59:58. When it becomes update timing of second information, a sub control part updates the second information to 58 s out of the time information stored in an update time storage area of RAM of a performance control board on the basis of the fact that the time represented by the time information of the RTC is 10:59:58. Similarly, the sub control part updates minute information, time information, day-of-week information, date information, month information and year information for each 100 ms. The sub control part executes a simultaneous performance and stores an error occurrence time on the basis of a time represented by the time information stored in the update time storage area of the RAM of the performance control board.SELECTED DRAWING: Figure 22 |
