Analysis of Isochronous real-time communication and PROFINET

Peng Jie Li Xiuyuan Ying QiJia

Abstract: PROFINET is a emerging standard of real-time Ethernet. In this paper, isochronous real-time communication of PROFINET is analyzed and enhancements to IEEE1588 are explained after two kinds of real-time communication in PROFINET are introduced. Key word: PROFINET; real-time communication; isochronous 1锛屾杩� 銆€銆€PROFINET瀵�(sh铆)鏅�(sh铆)浠ュお缍�(w菐ng)鏄敱Profibus
