在制造业和过程工业方面,数字总线协议的应用,历史上集中于专有通信方法。随着“现场总线”概念的到来,当所有的供应商都提供同样的开放式的协议时,将会有许多有前景的可预见的巨大效益。正如所能预见的,不同的供应商提供各自开发的以工业和应用为基础的解决方案,而非坐等普遍的通信协议。在过程控制中,每家已将他们的协议鉴定为“现场总线”。对于过程自动化,在不久的将来,现场和控制室检测仪表的前景将发生很大的变化。可互操作现场总线将会是使这些变化发生的隐形催化剂。 In the manufacturing and process industries, the application of digital bus protocols has historically focused on proprietary communication methods. With the notion of “fieldbus,” there will be many promising and predictable benefits when all vendors offer the same open protocol. As foreseen, different vendors offer individually developed industrial and application-based solutions rather than the more common communication protocols. In process control, each has identified their agreement as “Fieldbus.” For process automation, the outlook for field and control room instrumentation will change dramatically in the near future. Interoperable field buses will be invisible catalysts for these changes to take place.
