Abstract: With the rapid development of the national economy, automated warehouse in all walks of life will certainly be more widely used。 Automated warehouse is an important component of modern logistics system part of a multi-layer storage of goods, overhead storage system, the automatic control and management systems, computer management and control Systems and other auxiliary equipment components。 It is a control system designed to Siemens S7-200 series PLC to control the core, determine the system's control scheme, mainly control by manual and automatic in two different ways, position detection method, the electronic control system and field operation panel design, input/output point statistics, PLC hardware selection and configuration connections。 In this paper the feasibility of the project and the subject of the relevance and value realization are introduced; followed by the hardware components of the system, structure, principles are described and analyzed; once again the core of the control system -- the software was written Paper there is a corresponding ladder; Finally, the design of the subject knowledge and learned and summarized conclusions, and to be perfect in this paper a brief description of places。

Keywords: warehouse, programmable controller, input/output ports, S7-200
