制造系统对灵活性的需求正在不断增长。这需要处理建立设计方法，实现分布式应用程序。IEC 61499定义了一种基于功能块（FB）网络的分布式应用设计通用架构。控制软件和硬件之间的接口通过所谓的服务接口FB实现。但是，标准和可用工具都没有提供实现这种类型的FB的指导方针。另一方面，最广泛使用的工业通信标准之一是OPC，它使多供应商设备和控制应用程序之间的数据交换没有任何专有限制。因此，在IEC 61499应用中容易地集成该通信标准可以有助于巩固这样的标准。本文通过定义和实现OPC数据访问规范中的SIFB来访问过程数据，为OPC在工业应用中的应用提供了指导。
The need for flexibility in manufacturing systems is continuously growing. This need deals with the establishment of design methodologies for implementing distributed applications. The IEC61499 define a generic architecture for designing distributed applications, based on Functions Block (FB) networks. The interface between the control software and the hardware is achieved by means of the so called Service Interface FB. But guidelines to implement this type of FBs are provided neither by the standard nor by the available tools. On the other hand, one of the most widely used industrial communication standard is OPC that enables the exchange of data between multi-vendor devices and control applications without any proprietary restrictions. Thus, an easy integration of this communication standard within IEC61499 applications may contribute to consolidate such standard. This paper presents the guidelines to use OPC in industrial applications through the definition an implementation of SIFBs to access process data using OPC-DA (OPC Data Access) specification.
