Abstract

본 발명은 원격 입출력 유니트의 출력접점 제어 기술에 관한 것으로, 비상상태시의 안전한 출력접점의 값들은 시스템에 따라 상이함에도 불구하고 종래의 원격입출력 유니트에 있어서는 이와 무관하게 그 당시의 값이나 리세트값을 출력하게 되므로 예기치 못한 문제가 발생되는 결함이 있었는 바, 본 발명은 이를 해결하기 위하여 마스터에서 출력접점값 즉, 일정 시점에 주어진 시스템에 적합하고 사용자가 원하는 일정한 값을 비상 레지스터에 저장시킨 후 비상시 그 저장된 접점값이 출력되게 함으로써 비상 발생시에도 시스템을 안전하게 운전할 수 있는 효과가 있다.The present invention relates to an output contact control technique of a remote input / output unit. Although the values of safe output contacts in an emergency state vary depending on the system, the values and reset values of the conventional remote input / output units are irrelevant at the time. In order to solve this problem, the present invention solves this problem. In order to solve the problem, the present invention has an output contact value at the master, that is, a certain value suitable for a given system at a certain point in time and is stored in an emergency register by the user in an emergency register. The stored contact value is output so that the system can be operated safely even in an emergency.
