Networked control and monitoring system based on industrial Ethernet

Abstract

The proposed networked control and monitoring system based on industrial Ethernet has been successfully designed, installed, commissioned and completed in this paper. The system focused on reliable real-time communication transmission, intelligent management, automatic field & integrated control and data acquisition to support supervision of comprehensive information analysis. The hardware architecture and system philology design were introduced. Windows sockets and multi-threading technique to realize real-time and reliable transmission then were utilized in the system. This paper also emphasized the method that application accesses Windows system shared resources by utilizing I/O address redirection technique through Microsoft Network Client Software (MS-Client) under Disk Operating System (DOS) platform. The global production process status of the plant was supplied through monitoring system for managers to make better decision. Realtime, stability, reliability, safety of the whole system has been proved in practice.
