Abstract

PURPOSE:To improve the throughput between terminals each other, by controlling the transmission of the response of a repeating device connected to the main terminal to poling signals in terms of time. CONSTITUTION:By installing a data receiving judging section 20 and a poling response waiting section 21 to a repeating device to be connected to a main terminal and by setting the data transferring time between the repeating device connected to the main terminal and a repeating device connected to a secondary terminal as a specified time, data being received from the secondary terminal can be sent to the main terminal as the response to a poling signal when the reception of the data from the secondary terminal is completed within the specified time when the poling signal is received from the main terminal. On the contrary, when the reception is not completed within the specified time, a no- data signal is transmitted and these data are transmitted in the poling cycle just after the no-signal is transmitted. Therefore, the data transferring time from the secondary terminal to the main terminals can be shortened.
