Abstract :
In this paper we introduce a new UML stereotype, the Function Block Adapter (FBA), which is responsible for the connection of UML-RealTime capsules and function blocks of the IEC 61131-3 (standard for PLC programming languages). FBAs contain an interface to capsules as well as to function blocks and a description of the mapping between these interfaces. For this description a special FBA-language is provided. The FBA-language is easy to use both to UML-RealTime and to IEC 61131-3 developers, so they can unambiguously express the interface mapping. An important advantage of the FBA-language is the possibility of using it at an early design state of the UML-RealTime system. We explain our concept of FBAs by an application to a realistic manufacturing system
