Abstract
본 발명은 다수의 제어장치로 구성된 다중 제어 시스템에서 상기 제어장치간에 데이터를 공유하도록 한 데이터 공유 방법에 관한 것으로서, 주제어장치에 각 제어장치간에 공유하여야 할 데이타가 등록된 데이터 전달 테이블을 형성하고, 상기 주제어장치가 주기적으로 상기 데이터 전달 테이블에 따라 데이터가 전송되도록 제어함으로써, 제어 장치간에 일부의 데이터를 공유할 수 있으므로 주제어장치 및 부제어장치의 내부 메모리 사용을 보다 효율적으로 할 수 있고, 데이터의 전송 시간을 줄일 수 있으며, 부제어장치를 부가하여 시스템을 확장하고자 할 때 용이한 효과가 있다.The present invention relates to a data sharing method for sharing data between the control devices in a multi-control system consisting of a plurality of control devices, to form a data transfer table in which data to be shared between each control device is registered in a main controller, By controlling the main controller periodically to transmit data in accordance with the data transfer table, it is possible to share some data between control devices, thereby making it possible to more efficiently use the internal memory of the main controller and the sub-control device. The transmission time can be reduced, and there is an easy effect when the system is to be expanded by adding a sub controller.
