PLC (programmable logic controller) isa microprocessor asthe core ofindustrial control devices, itwill relay the traditional control bined puter technology in recent years inindustrial automation, mechanical and electrical integration, the transformation oftraditional industries such as generally applied. Asageneral-purpose industrial puter, the realization ofindustrial control wiring logical leap inlogic tostorage, industrial control inthe world isplaying anincreasingly important role. Inview ofthis, the designers ofthe use ofPLC functions and features designed abeverage filling production line control system. The article introduced the PLC beginning ofthe relevant knowledge, and then todrink bottling line asanexample, the use ofMitsubishi FX series programmable logic controller, PLC, introduced inthe beverage bottling line inthe application, given adetailed program design process. PLC control ofthe use ofbeverage filling production process, which can effectively improve the production efficiency offilling, and significantly increase the reliability ofcontrol systems and flexible. and take out the idea ofcontrol the level and pressure infully automated filling Gland with amore mature PID algorithm inthefield ofcontrol finally .
