Title: | Distributed automation with S7 simatic components | Authors: | Vo Nhu Thanh | Keywords: | Tia portal;S7-300;PROFINET;Automation | Issue Date: | 2012 | Publisher: | Vietnamese-German University | Abstract: | Automation has been widely used for a long time in many industries. It has been applied mostly in assembly line and production line. Automation has a lot of advantages such as increasing productivity, production quality control, saving labor, increasing operation time and production cycle reduction. Based on effectiveness of automation, it is proposed to apply the new Siemens Simatic S7-1200 in a production line for experiment and testing. The main point of this thesis is to design a completed automatic production line of selecting material to completely storage the final product in a shelf. The project will have 4 stations which were built and tested by the previous experiment using S7-300 CPU writing in Simatic Manager V 5.5 software. The first task is to translate the program of the S7-300 CPU to the program that could be loaded to S7-1200 CPU which would be written in Simatic TIA Portal V11 software. Those stations would be tested to work properly. The next step is to make the communication between all stations by PROFINET network. The final step is testing and correcting any defects and problems which may occur during the experiment. The main programs of the previous experiment for the S7-300 CPU were written in Graph and STL (statement list) language. However, the Graph and STL language were not supported by S7-1200 CPU. Therefore, the task is to import the programs from Semitics Manager to TIA Portal software and translate the programs which were written in Graph or STL into FBD (function block diagram) or LAD (ladder language diagram). Even though the FBD and LAD were more complex and longer to write than the Graph, they took less memory and faster for the CPU to process. Also when connecting these stations together by PROFINET, the switches from Siemens were used. As a result, these stations could be communicated in parallel as start topology. It means one station can send and receive data directly from others station. It VI was different to the master and slave system which was generally used by S7-300. For the star topology, the signal from one station to the other station would be faster and more rapidly. The production line finally worked properly. That was a very good experiment to work with the new Tia Portal software and the new S7-1200 CPU. The software Tia Portal was easier to program and handle the data; however, it required more powerful PC to run the software. The CPU S7-1200 is cheaper than others and strong enough to do any automation task. It would be the new technology that would be applied in all industrial to replace the old system. |
