(1) Through the user interface, IPC production formula and boot commands transmitted to the PLC;

(2) PLC received to production formula and started instruction, immediately according to formula content calculation the material of target volume, and according to the material of speed speed set to Organization production; while PLC accept operation button and site the trip or close switch of signal, by logic operation Hou output control following electrical, again by following electrical drive site implementation components of control coil, as electromagnetic valve and the exchange contact device, makes electromagnetic valve switch and motor run or stop;

(3) production process in the PLC constantly will scales bucket weight value and calculation out of target volume for compared, and according to ingredients net weight to decided fast, and slow speed signal of output or not; Dang a material distribution finished PLC will immediately calculation the material of errors value and drop repair comes as for Xia batch ingredients using; at if ingredients actual value beyond set of allowed poor range, system will pop-up dialogue box tips operator processing super poor; super poor processing completed and was confirmed Hou or ingredients super poor value in allowed poor range within, PLC Will start the other ingredients, such as that said only an item, allows unloading of PLC will issue a call signal; discharging is completed, PLC after batch compensation based on an amended target of starting the next batch of ingredients;

(4) the production process can be manual/automatic switch to intervene at any time in the production process; can also interrupt an item or ingredient of a scale all scales;

(5) other operating parameters (such as mixing and unloading delays, etc) through the interface, IPC send to PLC and save;

(6) the formula when the amount of all ingredients is complete, the system output and print detailed ingredients and end report.
