人们容易这么想,在工业应用中最简单和最好的解决方案是整个应用中都基于同一个现场总线的基础上。然而,Hayes控制系统的Stephen Hayes却赞成采用“omnibus”的解决方案,它把两种或更多的总线系统的优点结合起来。你可能认为,基于单一总线系统的安装要比使用多种总线系统的类似安装更易于设计、实现和维护。然而,关于这点,选择单一的总线系统必须更有效地处理其要求的所有任务。不幸的是,对于工业应用来说目前或可能永远不存在这样的 It is easy for people to think that the simplest and best solution for industrial applications is based on the same fieldbus throughout the application. However, Hayes Control Systems Stephen Hayes favors a “omnibus” solution that combines the advantages of two or more bus systems. You might think that a single bus system-based installation is easier to design, implement, and maintain than a similar installation that uses multiple bus systems. However, in this regard, choosing a single bus system must handle all the tasks it requires more efficiently. Unfortunately, this may or may not be the case for industrial applications
