A study on the Process Data Monitoring System using the Modbus Protocol

Modbus 프로토콜을 이용한 프로세스 데이터 모니터링 시스템 개발에 관한 연구

This Paper decribes a monitoring system using Modbus protocol and RS485 interface applied in many industrial field. We developed hardware to receive alanlog sensor output and monitoring program to communicate with hardware and carried out experiment with potentiometer for plan sensor, . Through online communication between Master and Slaves we convinced the usage of this systems. Also plant data file that saved in Excel format is convenient in writing various typs of documents.
