The design and debug of
PLC Siemens SIMATIC S7-300 series driven
Abstract：With the development of microprocessors, computers and digital communications technology, programmable logic controllers are widely used in almost all industrial sectors. It has the advantage of high reliability, easy operation and flexibility. This paper focuses on the application of Siemens PLC S7-300 for traffic lights, neon lights, water lights .besides,it also set out the design that how to use S7-300 and MM440 transducer to finish 5.5kW frequency conversion control system of AC motor design. Main hardwares are Siemens PLC S7-300, panels of traffic lights, neon lights and water lights , MM440 transducer and 5.5kW motor. Software is used primarily to prepare design of ladder diagram programs realizing the four controls. as a whole, design idea and features of this essay , meets all the design control requirements as a starting point, integrated and take into account other factors to ensure the safe and reliable design, operation is simple and practical. The first three of which were designed primarily to achieve control over light blinking light and death, and last 5.5kW motor frequency conversion control system mainly focus on motor speed control.
Key words:PLC, MM440, Ladder diagram
