필드버스 네트워크 상에서 임베디드 시스템을 이용한 ANSI/EIA 709.1 프로토콜의 분석

Fieldbus means industrial communication network especially siuted for real-time distributed control in automated systems. LonWorks is a kind of fieldbus that supports ANSI/EIA 709.1, and the LonWorks Protocol analyzers can be used for real-time analysis of data travelling through the LonWorks network when they are connected to the network. In many applications of LonWorks technology, protocol analyzers are necessary for checking proper operation and also for improved reliability of the network. In this study, a LonWorks protocol analyzer with the TMS320LF2406A based embedded system was developed and tested. Software for monitoring was designed using Visual C++6.0 on Windows XP environment. Performance of the developed analyzer was evaluated through a series of experiments of processing error, by measuring the speed of packet analysis.
