Abstract: The industrial－process measurement and control system is usually constructed by function blocks,but modeling with the UML－RT can be conducive to the expanding of the real－time control system,which requires the integration of the UML－RT components and function blocks in order to achieve the mapping of protocols between them.In this paper we introduce a new modeling element：Function Block Adapter（FBA）,which is responsible for the connection of UML－RT capsule and IEC 61499 function block.FBA provides interfaces to ports,to function blocks,and a description of the mapping between these interfaces.We also describe the concept,structure,interface and the execution model of FBA．

摘要： 分布式工业过程测量和控制系统常以功能块来构建,而利用UML－RT建模又便于实时控制系统的扩展,这要求集成UML－RT组件和功能块,实现UML－RT协议到功能块协议的映射。研究了用于连接UML－RT封装体和IEC61499功能块的模型元件：功能块适配器,它提供了同UML－RT封装体和功能块相交互的接口。描述了功能块适配器的概念、结构及接口,说明了功能块适配器的执行模型。
