Profibus Research And Application On Tobacco Primary Product Line

FCS is an open system network,as well as a fully distributed control system. OPC(OLE for Process Control),which based on Mierosoft's OLE(object linking and embedding)/COM technologies,is an industry specification and standard generated to settle the communication problem between industry client computer and virous equipment drivers. Based on the industrial fieldbus of PROFIBUS protocol, this article makes use of OPC technology to get the various real-time data needed for management network from the control network. Such process is characterized by efficiency, reliability, real-time and high speed. This leads to the real-time monitoring of the production line, and also provides the valid data acquisition for the real -time production demand, online quality control and preventive maintenance of equipments within the manufacturing execution system. All these bring production management level within tobacco enterprises into a new height.
