摘要

OPC UA是未来CPS场景中最重要的中间件候选者之一。它提供了许多概念，这些概念对于解决灵活性、安全性和可用性方面的挑战非常有用。它通过可扩展的OPC UA信息模型提供了语义丰富的信息空间。它们使开发具有高度灵活性的智能客户端应用程序成为可能。本文总结了使用OPC UA信息模型的经验。因此，它展示了我们使用OPC UA作为基础技术的各种项目。然后，我们描述了信息模型如何支持开发。另一方面，我们提供了一个关于这个信息模型的问题列表。OPC UA在修订管理和分布式应用方面有一些改进的潜力。

Information models in OPC UA and their advantages and disadvantages

OPC UA is one of the most prominent candidates for a middleware in future CPS scenarios. It provides many concepts which makes it very useful to address challenges in the area of flexibility, security and availability. It offers a semantic rich information space with extensible OPC UA information models. They make it possible to develop smart client application with a high degree of flexibility. This paper summarizes experiences made with the use of OPC UA information models. Thus, it presents various projects in which we used OPC UA as base technologies. Then, we describe how information models supported the development. On the other hand, we provide a list of issues which we experienced regarding this information models. There is some potential to improve OPC UA in the area of revision management and distributed applications.
