The international electrotechnical commission (IEC) is defined as of PLC programmable controller is a kind of digital computing operations, specially designed for the electronic system in industrial environment application and design. It USES programmable CunZhuQi, used in its internal storage to perform the logic operation,sequence control, timing, counting and arithmetic operation instruction, andthrough digital, analog input and output,the control various types of machinery or production process. Programable controller and related equipment, should press easy and industrial control system as a whole, easy to extend its function principle design. PLC with communication networking function, it makes PLC and PLC, between the PLC and the PC and other intelligent equipment to exchange information between, forming a unified whole, realize scattered centralized control. Most PLC has RS - 232 interface, and some built-in have to support their communication protocol interfaces. Ingredients workers receive daily production scheduling, will in turn for each feedstock. According to how much weighing ingredients, firs
