Based on the technology of PLC, servo, variable-frequency drive(VFD)and profibus field bus,in this paper, we use the method of establishing the communication between S7-200 and S7-300 by connecting S7-200 CPU with profibus-DP network and present a kind of automatic liquid filling and packing machine, with transportation, filling, covering lid and packing in the paper, the design solution, hardware configuration and programming have been shown. The experimental implementation has proved that the conveyor belt driven by PLC and VFD could not only improve the working efficiency and reduce the energy consumption, but also ensure safe and reliable transfer of the products. In packing process, the servo motor is used to control 3 degrees of freedom manipulator,can achieve much more accurate position control. Meanwhile, this kind of system provides the scalability and flexibility to add cleaning module of empty bottle and kick bad bottle, it also can be combined with 6 degrees of freedom manipulator to build a new filling system. It can be applied to the packaging system of modern production line. 
