Described in detail the automatic batching system design steps to focus on software development and debugging done, completed the ingredients of the hardware configuration and software design and use of Siemens WINCC real-time monitoring system design. Design of the main steps are as follows: first through the system determine the composition of the design, to draw the diagram; determine the device corresponding to the input and output, and the PLC in the corresponding address; procedures prepared by the PLC, after the completion of debugging; WINCC set up in the external and internal variables, then variables and corresponding graphics connections, in this process to the variable debugging and finally achieve animation. Through the design and co-ordination among the hardware and software debugging to meet the requirements of experimental design, and automatic control ingredients.
