In this paper we introduce a new profile for Function Block
Adapters (FBAs), which are responsible for the connection of Unified
Modeling Language (UML) ports and function blocks of non-UML languages.
FBAs provide interfaces to ports, to function blocks, and a description
of the mapping be-tween these interfaces. Both UML and function block
developers can use a spe-cial easy-to-use FBA description language to
express these interface mappings in a concise manner. Our FBA language
offers the important advantage of high-level descriptions during early
phases of the UML development process. This paper proposes a mapping of
FBA-semantics to standard UML-semantics. The application of FBAs to
function block oriented languages like IEC 61131-3, IEC 61499, or
Matlab/Simulink^(TM) is discussed by using the approach of the Model Driven
Architecture.
