企业应用程序的范围和重要性不断增加，因为这些信息系统允许更有效地利用企业时间和资源。企业应用程序正在检索有关处理来自外部数据源的数据的生产的信息。工厂车间设备是最重要的数据源之一。向信息系统公开车间设备信息和功能目前正在采用面向服务的体系结构（SOA）范式实现。Web服务设备配置文件（DPWS）是向设备提供服务功能的最常用技术之一。现代工厂信息系统通常是一组不断扩展的不同的、独立的应用程序，它们分别检索有关企业流程的信息。这些应用程序经常重复彼此的信息或功能。一旦应该消除应用程序之间的重叠，集成这些应用程序的必要性就出现了。在不断开发的系统中，在应用程序之间创建多个自定义集成通常不是一种有效的实践。面向消息的中间件（MOM）可以简化和标准化集成，提供中立的消息传递系统。目前，MOM和工厂信息系统通常使用动态打包系统（如OSGi）来实现。本文介绍的OSGi和DPWS互操作性的方法是基于DPWS适配器功能块的。该块可以部署在OSGi系统中，为特定的集成任务进行实例化和配置。该方法旨在引入企业信息系统与设备之间的松散连接。
Scope and importance of the enterprise applications are increasing constantly, as these information systems allow more effective usage of enterprise time and resources. The enterprise applications are retrieving the information about the production processing the data from outer sources. The factory shop-floor devices are among the most important data sources. The exposure of the shop-floor devices information and functionality to information systems is currently being implemented employing Service-Oriented Architecture (SOA) paradigm. Device Profile for Web Services (DPWS) is among the most employed technologies providing the service functionality to devices. The contemporary factory information system is usually a continuously expanding set of dissimilar, independent applications, which are separately retrieving the information about enterprise processes. These applications frequently duplicate information or functionality of each other. The necessity to integrate these applications emerges, once the overlap between applications should be removed. Creation of multiple custom integrations between the applications in constantly developing system, commonly, is not an effective practice. The Message Oriented Middleware (MOM) can simplify and standardize the integration, providing neutral messaging system. Currently MOM and factory information systems are often implemented employing dynamic packaging systems such as OSGi. The approach for interoperability of OSGi and DPWS presented in this article is based on the DPWS adapter function block. This block can be deployed in OSGi system, instantiated and configured for particular integration tasks. This approach aims to introduce the loose connection between the enterprise information system and devices.
