The Application Of PLC And Fieldbus Technology In The Transformation Of Packaging Unit B1

Unit B1 packing is the main model in cigarette factory of china.However,due to the introduction of a long time,the defects of the unit of electrical control systems become obviously in recent years,and it is difficult to meet the needs of today's generation due to the backward control unit.As a new type of industrial controller PLC has been increasingly widely used in the industrial control and in the cigarette industry be a high degree of promotion for it has lots of advantagements such as good general-purpose,high reliability,installation flexibility,the expansion of convenience,a number of advantages of higher cost performance,,he content of this research is the use of PLC technology to achieve intelligent packaging machine B1 transformation,the latest control technology and network technology are applied to the transformation process,improved the stability of the system unit and the machining accuracy.In this paper,at first give a overview of PLC control technology,network communication technology and human-machine interface technology,analysis of the B1 packing machine structure,working principle and process,give the transformation of the overall plan of the project,as well as the host machine through a small,FNZ/NK the transformation of content,On this basis,the setting S7-300 as the core of control unit si proposed,constitute a combination of PROFIBUS Fieldbus distributed control system,and with PRO-FACE GP2600 as a monitoring unit at the scene,sets IPC as the main station,to complete the programming and monitoring among three S7-300 station,adopting industrial WinCC configuration software and the GP2600 packaging systems to constitute B1 complex MHI. This paper discusses the hardware design and software design,gives the PRO-FACE GP2600 monitoring unit at the scene of the interface design and the related presentations.After transformation,the B1 packaging machine control system is maintained facilitately,scalability,running stability,and has friendly man-machine interface.Transformation of the PLC unit to achieve the overall automation of the unit and improve the reliability of the machine running,at the same time create conditions for the entire automation of the whole workshop even the whole factory in the future.
