the transmission-side apparatus acquiring the data from the monitoring target;
the transmission-side apparatus transmitting the data to the reception-side apparatus if the data has changed;
the reception-side apparatus receiving the data from the transmission-side apparatus; and
the reception-side apparatus determining whether a data loss is present,
if an abnormality is detected in communication with the reception-side apparatus, the transmission-side apparatus accumulates the data,
if the abnormality is recovered in the communication with the reception-side apparatus, the transmission-side apparatus transmits, to the reception-side apparatus,
accumulation data that is the data accumulated,
an accumulation start date and time of the accumulation data, and
an accumulation end date and time of the accumulation data, and
