•
1 like•1,005 views
1) The document discusses SysML modeling of co-simulation orchestration over the Functional Mockup Interface (FMI) as part of the INTO-CPS project. 2) The INTO-CPS project aims to build an integrated model-based design toolchain for cyber-physical systems covering the full development lifecycle. 3) Modelio is a UML modeling tool that provides SysML diagrams and modules for modeling CPS within the INTO-CPS framework.

- 16. alessandra.bagnato@softeam.fr • The Functional Mockup Interface (FMI) is a tool- independent standard to support both model exchange and co-simulation of dynamic models using a combination of XML-files and compiled C-code • The FMI standards currently specify two types of protocols: – FMI for Model Exchange (import and export), and – FMI for Co-Simulation (master and slave). • For FMI Model Exchange Import, the subsystem model is exported from a simulation tool in the form of an FMU archive containing the necessary FMU information (model description file, optional C source code, etc.); while in the FMI Model Exchange Export, the subsystem model is imported into the simulation system for system simulation. 16 Functional Mockup Interface (FMI)
