Analysis on the real-time data transmission in the IEC/ISA fieldbus

IEC/ISA 필드버스 시스템에서 실시간 데이터 전송 특성 분석

Fieldbus is the real-time communication network for process control and manufacturing automation systems. IEC/ISA fieldbus was proposed as an international standard of fieldbus network. This protocol is operated on the basis of token-passing and scheduling mechanism. In this paper, we analyze the performance characteristics of the 1996 version of IEC/ISA fieldbus systems.
