Abstract

장 자동화 기기의 복수개의 PCL(Programmable Logic Controller)에 프로그램 또는 내장된 자료를 지원해 주는 컴퓨터 링크 유니트(Computer Link Unit)에서, 이 컴퓨터 링크 유니트의 RAM에 저장된 데이타를 PLC의 CPU가 컴퓨터 링크 유니트의 CPU의 제어없이도 직접 read하거나 write할 수가 있다.In a computer link unit that supports programs or embedded data in a plurality of programmable logic controllers (PCLs) of automation equipment, data stored in the RAM of this computer link unit is stored in the CPU of the PLC. You can read or write directly without control.

따라서 데이타를 이용하는 시간이 종래보다 매우 빨라졌으며 회로의 구성도 더욱 간단해지는 효과가 있다.Therefore, the time to use the data is much faster than before, and the circuit configuration is simpler.
