Research On The Production Control System Of Pipe Grinding Based On Profibus

Programmable Logic Controller (PLC) is a kind of universal industrial apparatus whinch is developed rapidly and used widely in recent years, taking microprocessor as its integrating microcomputer technology, automation technology and communication technology.Because of its high performance, low cost and high reliability in the harsh environment. PLC has been widely used in industrial control areas.With a rapid development of PLC control technology at home and abroad, the application of PLC in controlling the grinding of the pipe industry also has a certain degree of development. In order to ensure the equipments run in security and under the stable environment.PLC is playing an enormous role. In addition, Profibus connects PLC to field devices. It has realized the correspondence between inputs and outputs of the PLC.In this paper, the main electrical control system is the Siemens S7-300 PLC. The STEP7 control procedures of the PLC complete a series of pipe grinding operation process, Compared to the earlier production lines,the Control System has changed radically. The fully automatic and intelligent operating system is used in new production lines, The electrical control system takes distributed architecture based on Profibus.The system of production control system has been applied, the actual running show. Pipe grinding stability, Grinding quality, efficiency have been enhanced in the system.
