摘要
介绍了 PROFIBUS现场总线的体系结构、访问方式、传送媒体等内容。并给出了工程应用的实例。以冗余 PROFIBUS现场总线为基础的新型分散控制系统用于燃机联合循环机组控制 ,远程 I/O机柜现场布置 ,实现了全厂监控 ,不仅降低了工程造价 。
A fieldbus technology-PROFIBUS is introduced.The system structure,access methods,protocols,and transfer media of PROFIBUS are described.Based on redundant PROFIBUS,a new type of distributed control system with remote I/O cabinets locating in the field is proposed for controlling and monitoring all subsys tems for a gas turbine combined cycle power plant.Compared with others,this system has a better performance and lower cost.
