Abstract: In order to solve the problems of high equipment failure in traditional spilled dyeing machine control system,the PLC technology and dyeing machine control object were investigated. After the analysis of machine principle of work and workflow,the relationship between PLC technology and spilled dyeing machine control system was established. The system design method using PLC and MPI network was put forward. It was realized that the system can control the equipment and get the system eqouiprment data. The system function,the configuration of hardware,input and output,control software modular structure were introduced. The research results show that the system is more flexible and so easy to overhaul. By programming control of dyeing process, labour and relay element component is reduced,work efficiency is advanced greatly,the automation of primary dyeing machine has been developed.
Key words: S7-200; PLC; spilled dyeing machine; control system; TD200; MPI
