Abstract

PURPOSE:To improve a reliability by providing a back up station for summing data inplace of a control station and updating a summing file at the time of the generation of an abnormality in the control station for summing the data of plural terminal equipments connected by a line. CONSTITUTION:Initially, a timer 1 is started, thereafter, a standby is executed until polling is present from the control station 1 to a self-station (for instance 4) or the timer 1 is time out. When the polling is not present to the self-station and the time is out, it is decided that the control station 1 stops the operation and the self-station 4 enters an agent operation as the control station. A polling signal is transmitted to other salve station (for instance, 5) to start a timer 2. Thereafter, the presence and the absence of a response from the slave station 5 are monitored in time by the timer 2. When there is the response within the time, a sales managing is updated by the data in a response telegraphic message sentence.
