Today, programmable controller (PLC )has been in all walks of life a wide range of applications and development, and Siemens series of PLC in PLC field in a wide range of applications. This paper mainly introduced PLC in on some of the engineering application, advantages and development status and prospect. Introduces Siemens PLC commonly used some products series classification and profibus-dp communication protocol and EM277 module. STEP7 used to study the S7-300 hardware configuration, Siemens S7-200 and Siemens S7-300 through the EM277 profibus-dp communication realized. Introduces profibus-dp in the application of drawing technology.
