【产品详情】

所有这些技术都基于传统的自动化金字塔，并不是在所有层面都是透明的。数据通过现场总线或 HART 从现场设备收集，并在 SCADA 级别转换以供应用程序使用。这些技术基于必须始终安装在终端设备上才能建立连接的软件产品。没有对数据进行进一步机器处理的规定。

在工业 4.0 解决方案的背景下为新技术的实施提供了太少的灵活性。因此，Namur（“过程工业自动化技术用户协会”）通过开放的 OPC UA 接口扩展了具有 NOA 概念（Namur 开放架构）的现有结构。Namur 开放式架构 (NOA) 描述了如何通过开放式 OPC UA 接口从现有自动化世界将数据导出到系统以进行监控和优化，同时让核心自动化任务基本不受影响。或者，第二个通信通道可以直接访问来自现有现场设备的信息。

【英文介绍】

All of these technologies are based on the traditional pyramid of automation and are not transparent at all levels. Data is collected from field devices via fieldbus or HART and converted at the SCADA level for use by applications. These technologies are based on software products that must always be installed on the end device to establish a connection. There is no provision for further machine processing of the data.

Too little flexibility is provided for the implementation of new technologies in the context of Industry 4.0 solutions. Thus, Namur (" Association of Process Industry Automation Technology Users ") extends the existing structure with the NOA concept (Namur Open Architecture) through the open OPC UA interface. Namur Open Architecture (NOA) describes how to export data from the existing automation world to systems for monitoring and optimization through an open OPC UA interface, while leaving core automation tasks largely unaffected. Alternatively, a second communication channel can directly access information from existing field devices.
