0 Summary With the rapid development of electronic technology, the demand for all-digital control system becomes more and more strong. Therefore, the fieldbus technology will become the mainstream control technology of the industrial automation control system in the 21st century. Fieldbus technology is in the market for intelligent field instruments and digital control system generated under the demand. From a technical point of view it is the inevitable product of the development of computer technology, network technology and control technology. At present, there are many kinds of field bus technologies, including INTERBUS, PROFIBUS, DeviceNet, Modbus and so on. 1 Project Introduction Yuxi Cigarette Factory pilot plant automation logistics system, including pilot plant tobacco leaves formula, auxiliary materials, finished products automatically storage, a library, automatic formula, raw materials with automatic control, production process monitoring, logistics management, tobacco formula, Accessories, finished product inventory management; also included
