Increasingly; innovative functionality in embedded systems is realized by connecting previously autonomous embedded systems. This requires real-time communication and coordination between these connected systems. Modelica and the StateGraph2 library provide a good environment for modeling embedded systems including controllers and physics. However; it lacks appropriate support for modeling the communication and coordination part.
In this paper; we present an extension to the StateGraph2 library that enables modeling asynchronous and synchronous communication and rich real-time constraints. We illustrate our extension of the StateGraph2 library by modeling and simulating two miniature robots driving in a platoon.
