PURPOSE:To know the status change in detail, by usually sampling all information at the same time and varying the sampling cycle of the information corresponding to the contents of the change in case the contents of the status information has some change. CONSTITUTION:The normal sampling timing is indicated by (a), and (T0) is the time that is previously permitted. All information is sampled at the same time within the time (T0). At the same time, the sampling cycle is indicated by (T1) and this cycle (T1) is set previously and is defined as the time that can be sampled once or several times in a transmission period. In such way, the status can be known at the same time for all information. In diagram, (b) shows the sampling timing in case all information is sampled with a timing (t1) a status change is detected to a certain status information. When the change of the status information is detected, only the information that is previously designated is sampled with the timings t2 and t3 according to the contents of the status change. |
