ation, mechanical and electrical integration, the transformation of traditional industries such as generally applied. As a generalpurpose industrial control puter, the realization of industrial control wiring logical leap in logic to storage, industrial control in the world is playing an increasingly important role. In view of this, the designers of the use of PLC functions and features designed a beverage filling production line control system. The article introduced the PLC beginning of the relevant knowledge, and then to drink bottling line as an example, the use of Mitsubishi FX series programmable logic controller, PLC, introduced in the beverage bottling line in the application, given a detailed program design process. PLC control of the use of beverage filling production process, which can effectively improve the production efficiency of filling, and significantly increase the reliability of control systems and flexible.
