基于功能需求分析的单一标准多功能现场总线探讨

制定单一标准多功能现场总线标准应以功能需求分析为基础，先分析生产现场对通信功能的需求，再分析流行的各种现场总线所线所能提供的功能，最后选出尽可能少的几种现场总线，使它们的功能总和满足现场功能需求，把这几种现场总线连入开放型现场总线控制系统平台，组成单一标准多功能现场总线，这种现场总线标准中包含的几种现场总线地位平等，具有再扩展能力，可以与管理网集成，进而联入国际互联网。

Deliberating of Single Standard Multifunctional Fieldbus Based on Function Requirement Analysis

Laying down the single standard multifunctional fieldbus criterion should be based on the function requirement analysis. At first,the communication function requirements of produce fieldse are analysed. Then,the functions provided by each prevailing fieldbus are analysed. Finally,We select the fieldbus as few as possible and make their total function meet the function requirements of produce fields.The selected fieldbus are connected to the open Fiedldbus Control System(FCS) platform and the single standard multifunctional fieldbus is composed. These selected fieldbuses in this fieldbus criterion are equal and possesses expandability. It could be integrated with the management net and connected into Internet.
