【Abstract】 With continuous development of integrated circuit and digital circuit,PLC is growing mightier from day to day in the respect of function,processing speed,intelligence and communication,and is now widely applied in various production fields. In the chemical industry,production process of organic silicon materials,regardless of raw materials,by-products,intermediate and final products,involves a variety of flammable,explosive and corrosive chemicals,has a high requirement for such parameters as temperature,pressure and liquid level. On this basis,we will use Siemens S7-300 PLC as the core to design a production monitoring system for organic silicon. The system is significant to the enhancement of productivity,accuracy control,safety performance and enterprise revenue.更多还原
