Design of Parts Processing and Control System Based on PLC

Abstract

This article focuses on the design of parts processing and control system based on Siemens S7-200 PLC. The purpose of this study is to learn and become familiar with the Siemens S7-200PLC hardware parameters and the use of programming software STEP 7 Micro/WIN SP9, and design a rational and effective parts processing and control system. This paper firstly describes the development history and development status of the PLC, so that readers can understand the PLC briefly. Secondly, the article shows some important technical parameters such as Siemens S7-200PLC CPU model, hardware configuration and so on. It is to clarify the basic component of parts processing and control system and its working principle, and the role of Siemens PLC in the system. Finally, according to specific design requirements, programming software STEP 7 Micro/WIN SP9 is used to program for the system so that the system can operate effectively and reasonably. The study successfully achieved the desired goals, through reasonable programming made PLC take the full control of parts processing in this system..
