Grafchart is a graphical programming language which extends Sequential Function Charts (SFC); the PLC standard languages for sequential; parallel; and general state-transition oriented automation applications. SFC is widely used and accepted for industrial automation. Grafchart adds higher level features to SFC such as hierarchical structuring; reusable procedures; and exception handling to make it convenient to implement and maintain large applications.
Functional Mock-up Interface (FMI) is a standard to combine dynamic system models for technical system developed in various tools. Tools can export models as Functional Mock-up Units (FMUs) which can be combined with other FMUs to compose the whole system.
In this paper adding FMI for Co-Simulation support to JGrafchart; a free implementation of the Grafchart language; is conceptually evaluated. It is discussed how JGrafchart fits into the FMI for Co-Simulation framework and potential ways to implement this are discussed.
