Abstract

In generation of communication data, continuous data capable of being acquired by a data logger is set as original data and the original data is sampled every a timing period t inputted. Since the original data and timing of sampling are displayed on the same screen, it can visually be checked which portion of the original is sampled and sent. In the timing of sampling, an initial point can be shifted. Assuming urgent time such as abnormal occurrence, a sending point for sampling the original data and generating and sending the communication data can be inputted and set at the time other than the sampling period t.
