Abstract: PURPOSE: To improve the reliability of a network communication system by providing a constitution in which a list A of internal data names is prepared at every station, a requester station sends its requests to all stations together with the data names, and the stations receive those requests and retrieve the list A to have the accesses to the corresponding data to return their access results to the requester station. CONSTITUTION: A DN retrieval table(LT) in which the data name(DN) to be stored in its own station are described is provided at each station 1 and every 3 to 8 stations. An access(Ac) requester station 1 produces an Ac request transmission frame based on the DN to which an Ac is requested through an application and on a command. These transmission frames are sent to the stations 3 to 8 of a network 2. Each of these stations analyzes the received transmission frame and retrieves the LT if the Ac is requested by the DN. The station 3 has an Ac if the DN is included in its own station. When this Ac is completed, the station 3 returns the answer data on the Ac result to other stations 1..., and no processing is applied to the station 1 if the stations 4 to 8 obtain no corresponding data through the same retrieval.  Thus the responsiveness, safety and reliability are improved for the data Ac performed among the stations.
