Abstract

PURPOSE:To increase the using efficiency for circuit of a system, by transmitting the state information of the latest system at all times to a specific station from a control station and performing centralized control of the state information at the specific station. CONSTITUTION:A specific station 1X is selected among plural stations which are connected in a loop via a data way DW. A host computer or a maintenance console 2 is provided to the station 1X. The information S on the system state is fed to the station 1X from a loop monitor controlling station 1Y. Based on the latest information S fed from the station 1Y, the station 1X replaces the old information respectively to reply to the request given from the host computer 2, etc. Thus a reply is given to the request for the system state via the computer 2, etc. and without using the data way DW each time. As a result, the using efficiency is greatly increased for the circuit, and at the same time the procedure is simplified.
