Abstract

PURPOSE:To make the data transmission efficient, by integrating the status change of other processes at the change time of a process status, which occurs in the period of polling from a master station, into one status change data. CONSTITUTION:Remote stations RS3 as the interface between a master station MS1 and processes are provided. The MS1 transmits the polling to the RS3, and the RS3 fetches data of the status change from one status to the other of the binary status change part of a corresponding process and transmits this data to the MS1 to monitor it. In this case, the RS3 fetches data, where the change to one status of other processes which occurs in the course of the change of the binary status of an optional process from one status to the original status through the other status is integrated, as one status change data in respect to status change data of the binary status change of the process at the polling time, and the RS3 transmits this signal to the MS1.
