Claims (5)

통신망 전송매체를 매개로하여 연결되는 스테이션은 메인 CPU와 주기억장치 및 통신망 인터페이스를 구비하고 있고, 이 통신망 인터페이스는 자신의 로컬 제어 프로세서 및 로컬 메모리로 된 중앙처리기와 통신권 획득을 위한 콘트롤러를 갖고 있는 분산 제어 시스템의 제어정보 고속 공유방법에 있어서, 자국의 메모리 공유영역에 대한 할당은 스테이션측의 사용자 설정에 의한 처리방법과, 상기 통신권 획득 콘트롤러의 통신권 획득에 준하여 상기 자국 공유영역 할정 정보를 상기의 콘트롤러를 통해 각 스테이션으로 전송하는 처리방법과, 상기 메모리 공유영역 할당 정보가 수신된 스테이션른 이에 준한 공유영역 테이블을 작성하여 예비해 두는 처리방법으로 이루어져, 에러 발생이 없는 경우 전체의 스테이션은 공유영역 할당에 대한 정보를 동일한 형태로 유지토록 하는 분산 제어 시스템의 제어정보 고속공유방법.A station connected via a network transmission medium has a main CPU, a main memory and a network interface. The network interface has its own local control processor, a central processor of local memory, and a controller for acquiring the right of communication. In the control information high speed sharing method of the distributed control system, the allocation of the memory sharing area of the own station is performed by the user's setting on the station side and the local area sharing area allocation information according to the communication right acquisition of the communication right acquisition controller. A processing method of transmitting to each station through the controller and a processing method of creating and preserving a shared area table corresponding to the station where the memory sharing area allocation information is received. Same information for share allocation Control information distribution method of the high speed shared control systems that maintain the form ever. 제1항에 있어서, 메모리 공유영역 중복설정에 따른 에러 발생의 경우 자국영역과 중복 발생시에는, 송신측에 중복 사실을 통보하고, 타국 영역과 중복발생시에는 수신된 공유영역정보를 무효화시키는 처리 방법을 포함하는 것을 특징으로 하는 분산 제어 시스템의 제어정보 고속공유방법.The processing method according to claim 1, further comprising a processing method of notifying a transmitting side of a duplication with said host area in the case of an error caused by overlapping of a memory sharing area, and invalidating the received shared area information when a duplication with another station occurs. Control information high speed sharing method of a distributed control system comprising a. 제1항에 있어서, 중복사실 수단에 따른 에러발생의 경우, 공유 데이타 전송의 중지와 이를 사용자에 에러정정 요구 통지를 처리방법을 포함하는 것을 특징으로 하는 분산 제어 시스템의 제어정보 고속공유방법.The method according to claim 1, further comprising a method of processing a suspension of shared data transmission and notifying the user of an error correction request in case of an error caused by duplication fact means. 제1항에 공유영역 관리 테이블에 등록없는 스테이션으로 부터의 데이타 수신에 따른 에러 발생의 경우, 이 데이타를 무효화시키고 송신측에 공유영역 할당 정보의 재송신을 요구하는 처리 방법을 포함하는 것을 특징으로 하는 분산 제어 시스템의 제어정보 고속공유방법.The method according to claim 1, further comprising a processing method of invalidating the data and requesting the transmitting side to resend the shared area allocation information in the case of an error caused by data reception from a station not registered in the shared area management table. High speed sharing method of control information in distributed control system. 제1항에 있어서, 스테이션의 삭제 또는 첨가는 전 스테이션에 이를 통지하고 공유영역 관리 테이블로부터 스테이션의 삭제 또는 등록을 행하도록 하는 단계를 포함하는 것을 특징으로 하는 분산 제어 시스템의 제어정보 고속공유방법.The method of claim 1, wherein the deleting or adding of the station comprises notifying all stations of the station and causing the station to be deleted or registered from the shared area management table. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
