According to the present invention, a system for a motor control board comprises: a first integration module and a second integration module which are installed to correspond to a motor control board and to be dual; a plurality of protection control modules installed to correspond to each motor unit; and a multi-point bus connected to the plurality of protection control modules to configure a serial communication network among the first integration module, the second integration module and the plurality of protection control modules. One end of the multi-point bus is commonly connected to a first serial communication port of the first integration module and a first serial communication port of the second integration module. The other end of the multi-point bus is commonly connected to a second serial communication port of the first integration module and a second serial communication port of the second integration module. Therefore, the system for a motor control board enables simultaneous dualization of the integration modules and internal communication. 본 발명에 따른 모터제어반용 시스템은, 모터제어반에 대응하여 설치되며 이중화된 제 1 통합모듈 및 제 2 통합모듈; 각 모터유닛에 대응하여 설치되는 복수의 보호제어모듈; 상기 제 1 통합모듈 및 상기 제 2 통합모듈과 상기 복수의 보호제어모듈의 사이에 시리얼 통신 네트워크를 구성하기 위하여, 상기 복수의 보호제어모듈이 접속되는 멀티포인트 버스;를 포함하되, 상기 멀티 포인트 버스의 일단은 상기 제 1 통합모듈의 제 1 시리얼 통신 포트와 상기 제 2 통합모듈의 제 1 시리얼 통신 포트에 공통 연결되며, 상기 멀티포인트 버스의 타단은 상기 제 1 통합모듈의 제 2 시리얼 통신 포트와 상기 제 2 통합모듈의 제 2 시리얼 통신 포트에 공통 연결되는 것을 특징으로 한다.
