【正文】 n the domestic market large market share, because of its flexible and powerful munication features and other special advanced features are increasingly the more widely used in automatic control systems [1]. Siemens Automation and Drives Group is currently actively cooperate with colleges and universities Siemens to build the establishment of training center for smallscale automation, Qingdao University is one of them. Siemens to provide similar training center S7200 trainingrelated equipment and software development. Teachers take advantage of this favorable experimental conditions, based on the design of these devices to open .Made a number of pilot projects PLC open, so that school has spare capacity, enough to further strengthen the PLC application technology student learning, Understand and operate the most advanced automation equipment, the initial grasp of advanced control technologies of industrial automation and control system design technology patients, improve their practical ability to achieve training objectives applicable talents to meet munity needs for such technical personnel requirements. 1 Modular S7200 training equipment 2 Principle and Application of PLC technology to learn and master the necessary hardware and software test platform to support. Siemens automatic in my school Group set up jointly with the driver of a small automated training centers, equipped with 10 sets of training equipment S7200, diagram at right .Figure (painted on some of the expansion module) below. The device is modular in design, the main module in addition to superior performance, costeffective .Higher CPU 224XP host, but also es with text display TD400C, with special PT100 temperature transmitter, Heaters, fans, and other physical control object, basic literacy training to achieve most of experiments, people could be conducted. Siemens products for the rich function module, consider the cost and other factors, with a certain number of functional modules, including EM231 RTD temperature measurement module, EM253 position control module, EM241 Modem munication module, CP2431 Ether munication module, EM277 PrefabsDP module, SP series weighing Siwarex MS weighing module sensors and extension of six modules, connected by bus expansion unit to achieve the function of switchfree wiring, training, experiments can be used interchangeably. Also es with HMI (Human Machine Interface) devices TP177B, OP177B, MP277, etc. A total of 10 touchscreens, hanging in the equipment rack can also be supported by a separate operation. Using the standard package of equipment S7300 rail card installed, so that reliable and stable module is installed, and when necessary S7300 modules can be very easy to experiment with the addition of any module S7300, the S7200 and S7300 the installation of a mon platform. This experimental equipment for teaching, training and scientific research has provided teachers, good hardware conditions. 2 PLC open to experimental design PLC courses each semester due to class a lot, by the laboratory equipment, space and curriculum hours restrictions, generally Principle and Application of PLC programs created in the experiment mainly supporting the basic instruction to practice, sequential control, a simple digital Volume control system design, such as the marquee design, automatic round trip transportation movement control, intersection traffic lights model control, Threetier model of control of the
