The application of S7- 300 PLC in airfoil dynamic balance test platform
Liu Shi · Applied science and technology · 2008
In order to meet the requirements of airfoil balancing test platform on data acquisition and control system,the relevant control circuit for switching value and the processing methods for analogue value were designed, which implemente the functions and interlocks of all control circuits and accurately read the analogue data from various sensors. In the control system, the Siemens S7- 300PLC and the corresponding input and output modules were employed. In PC configuration software, Fame View was used to realize a real- time monitoring of the equipments and parameters of entire system. The man- machine interfaces are friendly. Since the data types transferring to PC are reduced,the speed of data collection is substantially improved, thus meeting the design requirements of the system.
