Abstract
본 발명은 디지탈 출력보드의 이중화 장치 및 방법에 관한 것으로, 특히 현장의 중요 디지탈 접점을 제어할때, 이중화된 출력보드중 어느 한 보드가 고장시 대기중에 있던 또 하나의 보드가 출력을 내어 연속적인 제어가 가능하도록 함과 아울러 고장이 발생한 보드를 보수할 경우에 전체 시스템에 영향을 최소화 하도록 하는 디지탈 출력보드의 이중화 장치 및 방법에 관한 것으로, 종래에는 보드 한장에 같은 회로로 디지탈 출력보드를 이중화함으로써 중요부위가 고장이 발생할 경우에는 이 이중화 출력보드는 동작하지 못하게 되고, 이로인해 유지보수시에 필수적으로 최종출력이 교체시간동안 단절되어 현장계기를 제어하지 못하게 되는 문제점이 있었으나, 본 발명에서는 회로를 각기 다른 두장의 보드에 구성함으로써 어느 한 보도에 고장이 발생하더라도 완전히 독립적인 다른 한 보드에 위해서 계속적으로 현장계기를 제어하도록 하여 어느 한 보드의 유지보수시에도 현장계기를 제어하지 못하는 순간은 발생하지 않게 됨으로써 이중화 장치의 신뢰성을 향상시키는 효과가 있게 된다.The present invention relates to an apparatus and a method for duplicating a digital output board, and more particularly, to a system and method for duplicating a digital output board, in which, when controlling important digital contacts in a field, The present invention relates to a digital output board redundancy apparatus and method for minimizing the influence on a whole system when a faulty board is repaired. In the related art, conventionally, a digital output board In case of a failure of a critical part, the redundant output board fails to operate, and thus the final output is disconnected during the replacement time, which is essential in maintenance, and thus the field instrument can not be controlled. However, By configuring the board on two different boards, Even if it is possible the effect of improving the reliability of a fully independent continuously moment can not control the field devices during maintenance of one board so as to control the field devices is not emitted by a redundant device to another on the board.
