Abstract: 본 고안은 고장에 대한 코드를 표시하는 장치가 내장되어 있는 피엘씨에 관한 것이다.
본 고안은 기본적으로 피엘씨의 중앙처리장치(1)에 고장표시기(6)를 설치하고, 종래의 통신유니트에서 공정감시 모니터(5)로 전송하던 정보를 상기 고장표시기(6)의 입력에 인가함을 원리로 한다.
본 고안에 의하면 피엘씨의 고장 상태가 코드화되어 피엘씨에 장착되어 있는 고장표시기에 직접 표시되므로, 시리얼통신 케이블(3)에 고장이 있는 경우에도 정확하게 에러 또는 고장을 알 수 있고, 현장 작업자들이 원거리에 위치한 중앙감시반까지 이동할 필요가 없이 피엘씨의 상태를 알 수 있어서 보다 신속하고 정확하게 에러 또는 고장에 대한 심층 처리를 할 수 있는 매우 획기적인 효과가 있다.
