Abstract
Mixing system is typical modern machinery and equipment, in the chemical industry, road construction and building industry has a wide range of applications. The purpose of this design is to use modern PLC technology to control chemical blending system. This design first introduced the PLC technology development present situation as well as the basic purpose of this design, introduced the design chooses the basic working principle of Mitsubishi PLC and PLC. This secondary at the same time to control the chemical mixture system function and the working process are analyzed, and determine the overall scheme design, the system analyzes the input and output points of computing. Determine the basic models of PLC (FX2N -16 MR ), to account for the selection of other equipment in the design. Finally, this time design drawing of the electrical schematic diagram and ladder diagram of control system and the corresponding statement table.Keywords: Mixing System; PLC; System Control; Mitsubishis; CAD
