CIM 시스템의 Infrastructure(DLU & DAU) 구성을 위한 통합 모니터링 시스템의 개발(I)

This paper describes a multi-computer system developed for CIM(Computer Integrated Manufacturing) system, which combines single board computers and personal computers by using RS422/485 communication and LAN. The system adopts a concept of hot run back up system based on dual CUP system of host and supervisor structure. The dual CPU system and the single board computer are respectively developed using 32 bits microcomputer and 16 bits microprocessor. 8097BH. The multi communication between two types of system is done by using RS 422/485, and also data logging computers are linked with LAN.
