PROFIBUS混合系统通信技术应用研究

现场总线控制系统是信息数字化、控制分散化、开放互可操作的新一代自动化控制系统。它是信息技术、智能化、数字化、网络化向工业现场的发展。本文就PROFIBUS的协议，并结合应用对多主多从系统的互联通信技术进行了一定的阐述。

：FCS is a new automatic control system .It is characterized by information digitalization，control system distribution，open and inter-operation. It is the result of information technology，digitalization，intelligence technology and network technology developing to the industry field. The protocol of PROFIBUS is introduced in this paper, which combines inter-linkage communication technology of Hybrid system (multi-master station and multi-slave station).
