Integrating UML-RT and Function Block with Function Block Adapters

摘要

The modeling of complex control system is usually based on the UML, thus the distributed control system is generally constructed by function block. This paper studies the modeling element: Function Block Adapter,which responsible for the connection of UMLRT capsule and IEC 61131 function block. By an application to a realistic manufacturing system, the author describes the concept,structure and interface of FBA. This paper also discusses a special FBAlanguage,which defines the operation of FBA.
