Abstract: In today's society is a society rapid development of science and technology, people's life becomes more and more convenient, the emergence of a variety of technology products greatly improved people's quality of life, and the vending machine is one of them. This design is introduced based on Siemens S7-200 series PLC and configuration software kingview for vending machine control system design scheme, and also expounds the source and development of vending machines, as well as the present situation of its at home. Programmable controller (PLC) has a strong ability to control, flexible operation, high reliability, and suitable for the characteristics of continuous work for a long time, is widely used in industrial field. This paper adopts Siemens PLC ladder diagram dedicated editing software step7 to write, in a transaction process, for example, to the whole process can be pided into several parts, including "coin program", "green lights program", "application of choose and buy" and "change program", and then for each part of the application programming, using configuration software for control system to conduct a comprehensive monitoring, to ensure the normal and stable operation of the vending machine.
Key words: The vending machine, Programmable controller, Configuration software
