Research and realization of a spinning machine control and monitoring system by industrial ethernet communication between IPC and OMRON PLC

This paper is about the research on the industrial Ethernet communication between industrial PC (IPC) for a spinning machine and OMRON programmable logic controller (PLC) based on FINS protocol and Winsock in VC++. This proposed networked communication has been successfully designed, installed, commissioned and realized. This paper focused on reliable real-time communication transmission and integrated control between PC and PLC for the spinning machine control system. The hardware architecture, system philology and programmed control software were briefly introduced. Windows sockets threading technique and FINS protocol integrated with the Ethernet unit CJ1W-ETN21 in OMRON PLC to realize the real-time and reliable communication transmission were utilized in this paper. The control of spinning machine was achieved by realizing the networked communication between IPC and PLC. Real-time, stability, reliability, safety of the whole system has been proved in practice.
