Title Motion control of screw based on PLC Micro850
Abstract
With the social development, science and technology, industrial production has been rapid development, which create a rich wealth for society, but also brought a series of problems,such as resource depletion, environmental pollution and so on.the emergence of this series of problems, warning people in accelerating development, we must also focus on the harmonious development between man and nature.to address these issues, the public is actively exploring.in industrial production, automatic control, not only to ensure a stable and secure operation of the production process, but also to reduce costs, improve quality, reduce waste emissions, automatic control technology has become an important way to solve these problems.
This article is in this background, the design of screw’s motion control based on Rockwell Micro850 PLC, including hardware circuit design and software programming, and focused primarily on programming and configuration software debugging.software programming language used in this design is the most commonly used in PLC programming called ladder diagram.

1.1 研究背景
随着社会发展，科技进步，工业生产得到快速发展。生产规模由小到大，工业产品由粗到精，产品产地由分散到集中，为社会创造出丰富的财富，极大地提高了人们的物质生活。但是同时也出现了一系列的问题，资源的枯竭，环境的污染等等。这一系列问题的出现，警示人们在加快发展的同时，要更加关注人与自然的和谐发展。
为了解决这些问题，各界人士正在积极探索。在工业生产中，自动控制不但能够保证生产过程稳定安全运行，还能够降低成本、提高质量、减少废物排放，自动控制技术成为解决这些问题的重要途径。
