B1 packaging unit is a lot of cigarette factory , the main model . However, due to the introduction of a long time , in recent years, the unit of electrical control system defects has become increasingly prominent , and the unit control backward , it is difficult to adapt to today's generation needs . PLC as a new type of industrial controller , with its versatility , high reliability , and flexible installation and easy expansion , high cost performance advantages to be more widely used in industrial control , the cigarette industry been a large degree of promotion . The content of the research is the use of PLC technology achieve B1 packaging machine , intelligent transformation , the latest control technology and network communication technology applications to the transformation process , and improve the unit system stability and machining accuracy . This paper first reviews PLC control technology , network communication technology and the development of man-machine interface technology , analysis of the structure , working principle and process of the B1 packaging machine , project transformation of the overall program , as well as a host of small through machine , FNZ / NK transformation of content , based on using the S7-300 as a core control unit , combined the PROFIBUS fieldbus constitute the distributed control system , and using the PRO-FACEGP2600 as site monitoring unit , the IPC IPC as the main station , completed three S7-300 from the station 's programming and monitoring , the use of composite MHI industrial configuration software WinCC the GP2600 together constitute B1 packaging machine system . This paper discusses the system 's hardware and software design , interface design and introduction of the PRO-FACE GP2600 - site monitoring unit . After transformation B1 packaging machine control system and easy maintenance , scalability , stable operation , friendly interface . PLC transformation of the unit to achieve the overall automation of the units , to improve the reliability of the machine running , at the same time to create the conditions for the entire workshop in the future and the whole entire plant automation .
